    Appeal from denial of motion for new trial on grounds of

    CADY, Justice.
    In this appeal from a judgment entered by the district court
    following a jury verdict in a breach-of-contract action, we must primarily
    consider the parameters within which the district court may resolve and
    correct inconsistencies in a verdict and reform the jury’s answers to
    questions in the verdict in lieu of granting a new trial. We conclude the
    district court erred in failing to grant a new trial in this case. We reverse
    and remand for a new trial on all issues.
    I.    Background Facts and Proceedings
    Clinton   Physical   Therapy   Services,   P.C.   (CPT)   is   an   Iowa
    corporation with its principal place of business in Clinton. It also has
    offices in DeWitt and Davenport, Iowa and Morrison and Savanna,
    Illinois. On April 15, 1996, CPT entered into a contract with John Deere
    Health Care, Inc. (John Deere), a health maintenance organization, to be
    a “network provider” of physical therapy services to John Deere plan
    members.    The Davenport office was not in existence at the time the
    contract was executed, and the agreement was silent on which of CPT’s
    offices were covered by the agreement.
    The Davenport office, also called the Plaza office, opened in August
    1997. CPT notified John Deere of the new Davenport office by letter on
    August 11 and indicated it wanted the office to be covered by the
    network-provider contract.      John Deere initially paid for services
    provided at the Davenport office, but claimed it did not realize the
    payments were for services performed at the office at the time the
    payments were made. It later took the position that the office was not a
    covered facility under the contract, and denied claims for services
    performed at the Davenport office.
    3
    John Deere sent CPT letters on April 23 and June 1, 1999 stating
    the Davenport office was not covered by the contract. Nevertheless, CPT
    continued to provide services to John Deere plan members at the
    Davenport office. Ultimately, CPT provided services to approximately 300
    John Deere plan members over 2775 visits at the Davenport office
    without reimbursement from John Deere at the $50-per-visit rate under
    the contract.       This amounted to $138,750 in unpaid services up to
    August 2001. Of this amount, $128,200 in services were rendered after
    John Deere notified CPT in writing that services at the Davenport office
    would not be paid.        In August 2001, the parties entered into a new
    contract. The new contract contained a specific clause indicating that
    John Deere had discretion to pay for services provided by CPT at a new
    office location.
    In February 2003, CPT brought a breach-of-contract action against
    John Deere.        CPT claimed John Deere breached the 1996 contract by
    refusing to pay for services provided to John Deere plan members at the
    Davenport office.      John Deere claimed the Davenport office was not
    covered by the contract. It also claimed that even if it was covered, CPT
    failed to mitigate its damages by continuing to treat John Deere plan
    members at the Davenport office after receiving notice from John Deere
    that the services would not be reimbursed, and not billing the plan
    members for the services. 1
    1The failure-to-mitigate-damages issue appears to be based on Restatement
    (Second) of Contracts section 350. Comment b to this section provides:
    As a general rule, a party cannot recover damages for loss that he
    could have avoided by reasonable efforts. Once a party has reason to
    know that performance by the other party will not be forthcoming, he is
    ordinarily expected to stop his own performance to avoid further
    expenditure. . . . The amount of loss that he could reasonably have
    avoided by stopping performance . . . is simply subtracted from the
    amount that would otherwise have been recoverable as damages.
    4
    The case was tried to a jury.              At trial, CPT offered the 2001
    contract into evidence as an aid to interpret the 1996 contract. John
    Deere claimed the clause pertaining to new locations in the 2001
    contract was in the nature of a subsequent remedial measure and was
    not relevant. The district court excluded the contract from the evidence.
    The case was submitted to the jury on a verdict form that required the
    jury to answer a series of questions and determine the amount of
    damages in the event a breach of contract was established. The form
    provided:
    We find the following verdict on the questions
    submitted to us:
    Question No. 1: Did the terms of the contract allow
    for the Plaintiff to add its new Plaza or North Scott location
    by providing written notification to Defendants of the
    opening of that office?
    Answer “yes” or “no.”
    ANSWER:        _____
    (If your answer is “no,” do not answer any further
    questions)
    Question No. 2: Did the Plaintiff comply with all the
    terms of the contract that were required unless excused?
    Answer “yes” or “no.”
    ANSWER:        _____
    (If your answer is “no,” do not answer any further
    questions)
    Question No. 3: Did            the    Defendant      breach      its
    contract with Plaintiff?
    ________________________

    challenge the application of this defense, and we do not express an opinion as to
    its applicability.

    ANSWER:       _____
    (If your answer is “no,” do not answer any further
    questions)
    Question No. 4:         Did the Plaintiff fail to mitigate its
    damages?
    Answer “yes” or “no.”
    ANSWER:       _____
    Question No. 5: State the amount of damages
    sustained by the Plaintiff as to each of the following items of
    damages:
    A.     The reasonable value, at the contracted rate, of
    outstanding charges for treatment provided by Plaintiff in its
    Plaza facility to Defendants’ eligible members from 1997
    through July 31, 2001.
    $ ___________
    B.    The reasonable value of Plaintiff’s lost profits
    from the loss of referrals of Defendants’ members to its Plaza
    facility from 1997 through July 31, 2001.
    $ ___________
    Question No. 6: State the amount of damages which
    Plaintiff failed to mitigate.
    $ __________
    Question No. 7: State       the   total    amount     of
    recoverable damages to the Plaintiff. (The total of the answer
    to Question 6 minus the total of the answer to Question 7). 2
    $ __________
    The parties consented to a sealed verdict, which permitted the jury to be
    discharged after reaching the verdict without reporting its findings in
    open court in the presence of the parties. See Iowa R. Civ. P. 1.931(3)
    (“When, by consent of the parties and the court, the jury has been
    2The   parenthetical instruction in question 7 contained a mistake and was
    intended to tell the jury the answer to question 7 was the difference of question 5
    (subparts A and B) minus question 6 (not question 6 minus question 7).
    6
    permitted to seal its findings and separates before it is rendered, such
    sealing is equivalent to a rendition and a recording thereof in open court,
    and such jury shall not be polled or permitted to disagree with respect
    thereto.”).
    After a period of deliberations, the jury notified the judge that it
    had reached a verdict. The judge discharged the jury without notifying
    the attorneys for the parties. In response to the first three questions in
    the verdict, the jury found that the network-provider contract did allow
    CPT to add the Davenport office, that CPT complied with all the terms of
    the contract, and that John Deere breached the contract. In response to
    question 4, the jury found that CPT did not fail to mitigate its damages.
    It then found CPT suffered $138,750 in damages in response to question
    5, subpart A. These damages were defined as the reasonable value of the
    service provided to John Deere members at the Davenport office from
    August 1997 through July 2001. However, question 6 required the jury
    to state the amount of damages CPT failed to mitigate.            The jury
    answered $128,200. Finally, the jury found the total amount of damages
    CPT could recover was $10,550. The district court entered a judgment
    for $10,550 in favor of CPT.
    CPT subsequently filed a motion for a new trial.       It claimed the
    verdict was inconsistent because the answers showed the jury found it
    did not fail to mitigate damages yet found its damages should be reduced
    by $128,200. It claimed this inconsistency warranted a new trial under
    Iowa Rule of Civil Procedure 1.1004(5).     CPT also asserted that a new
    trial was warranted because the district court erred in failing to admit
    the 2001 contract into evidence.
    John Deere resisted the motion for new trial. It argued CPT waived
    its right to a new trial by agreeing to a sealed verdict and failing to move
    7
    for   resubmission   of   the   case   before   the   jury   was   discharged.
    Alternatively, John Deere argued the verdict was not so logically
    inconsistent that it could not be harmonized.
    John Deere claimed that a reasonable explanation existed for the
    inconsistent answers based on the changes in the damage figures made
    by the jury on the verdict form.       The verdict form revealed the jury
    originally inserted $10,550 for the total amount of damages sustained by
    CPT (value of services provided from 1997 to 2001) in response to
    question 5, subpart A. It also originally inserted zero in response to the
    request in question 6 to state the amount of damages CPT failed to
    mitigate.   Thus, up to this point, the verdict answers were not
    inconsistent, and John Deere theorized that the jury had decided that
    CPT’s damages were limited to reimbursement for services it provided
    prior to the time John Deere notified CPT in 1999 that it would not
    provide reimbursement. Question 7 then informed the jury to determine
    the “total amount of recoverable damages” by subtracting the amount of
    damages CPT failed to mitigate from CPT’s total damages (reasonable
    value of services provided from 1997 to 2001). At this point, John Deere
    surmises that the jury understood it needed to show its math by
    subtracting the amount of damages CPT failed to mitigate from the total
    value of the unreimbursed services rendered over the course of the
    contract. John Deere believed the jury went back to questions 5 and 6 to
    show its math, but neglected to return to question 4 to change its answer
    to “yes,” consistent with the procedure required under the instructions to
    reach the recoverable amount of damages.
    The district court determined that CPT did not waive the
    inconsistency issue by failing to object before the jury was discharged.
    However, the court denied the motion for new trial on its merits. The
    8
    court accepted John Deere’s explanation that the jury intended for its
    answers to be consistent. The court then reformed the jury’s answer to
    question 4 (“Did the Plaintiff fail to mitigate its damages?”) to “yes” to
    conform to the remainder of the verdict, and concluded that “[t]he jury’s
    determinations were not inconsistent and the verdict effectuate[d]
    substantial justice between the parties.”
    CPT appealed. It claimed the district court erred by failing to grant
    a new trial based on the inconsistent answers in the verdict.            We
    transferred the case to the court of appeals.        The court of appeals
    affirmed, reasoning that while the jury’s answers to questions four and
    six were “facially . . . inconsistent,” the jury must have intended to find
    that CPT failed to mitigate its damages because it reduced the total
    damages by $128,200—the amount of damages CPT sustained after
    John Deere’s April 1999 notice that the Davenport office was not covered
    under the contract.    It also found the district court did not abuse its
    discretion in failing to admit the 2001 contract into evidence.         CPT
    applied for further review, which we granted.
    II.   Standard of Review
    “ ‘The scope of our review of a district court’s ruling on a motion for
    new trial depends on the grounds raised in the motion.’ ” Richards v.
    Anderson Erickson Dairy Co., 
    699 N.W.2d 676
    , 678 (Iowa 2005) (quoting
    Channon v. United Parcel Serv., Inc., 
    629 N.W.2d 835
    , 859 (Iowa 2001)).
    If the motion for a new trial was “ ‘based on a discretionary ground, we
    review it for an abuse of discretion.’ ” 
    Id. (quoting Roling
    v. Daily, 
    596 N.W.2d 72
    , 76 (Iowa 1999)). In contrast, if the motion was “ ‘based on a
    legal question, our review is on error.’ ” 
    Id. (quoting Roling
    , 596 N.W.2d
    at 76).
    9
    In this case, the underlying ground for the motion for new trial was
    based on a claim of inconsistent answers in the verdict. Generally, the
    trial court has some discretion when faced with inconsistent answers in
    a verdict. See Dutcher v. Lewis, 
    221 N.W.2d 755
    , 762 (Iowa 1974) (“The
    trial court has three alternatives where the answers are consistent with
    each other but inconsistent with the general verdict: (1) order judgment
    appropriate to the answers notwithstanding the verdict; (2) order a new
    trial; or (3) send the jury back for further deliberations. Ordinarily, it is
    discretionary with the court as to which of these alternatives to choose.”).
    However, the question whether a verdict is inconsistent so as to give rise
    to the exercise of that discretion is a question of law. See Redmond v.
    Socha, 
    837 N.E.2d 883
    , 895 (Ill. 2005) (“[W]hether two verdicts are legally
    inconsistent is a question of law.”); State v. Leake, 
    699 N.W.2d 312
    ,
    325 (Minn.) (“The question of whether verdicts are legally inconsistent is
    a question of law . . . .” (Citation omitted.)), cert. denied, ___ U.S. ___, 
    126 S. Ct. 745
    , 
    163 L. Ed. 2d 583
    (2005); accord State v. Harris, 
    983 P.2d 881
    , 884 (Mont. 1999); State v. Thompson, 
    971 P.2d 879
    , 891 (Or. 1999).
    Therefore, we review the district court’s conclusion as to whether
    answers are inconsistent for correction of errors at law. See 
    Richards, 699 N.W.2d at 678
    (stating when a motion for a new trial “ ‘is based on a
    legal question, our review is on error’ ” (quoting 
    Roling, 596 N.W.2d at 76
    )). We generally review the admission of evidence at trial for an abuse
    of discretion. State v. Price, 
    692 N.W.2d 1
    , 3 (Iowa 2005) (citing State v.
    Dullard, 
    668 N.W.2d 585
    , 589 (Iowa 2003)).
    III.   Verdict
    We first address the argument by John Deere that CPT waived its
    right to seek a new trial based on inconsistent answers in the verdict by
    consenting to a sealed verdict. When parties agree to a sealed verdict,
    10
    they lose their right to have a verdict returned in open court where
    inquiry can be made into its findings.       See Iowa R. Civ. P. 1.931.
    Consequently, it is not possible to use additional deliberations as a
    remedy for an inconsistency in a verdict when a sealed verdict is used in
    a case. However, further deliberation to remedy an inconsistency in the
    verdict is only one available remedy. The other remedies are to grant a
    new trial or attempt to reconcile the inconsistencies. 
    Id. r. 1.934.
    Thus,
    a sealed verdict may constitute a waiver of the additional-deliberations
    option, but it would not constitute a waiver of other remedies. CPT did
    not waive its right to request a new trial by agreeing to a sealed verdict.
    Thus, we proceed to consider the merits of the claim.
    Jury verdicts in Iowa can be in the form of a general verdict,
    special verdict, or general verdict with special interrogatories. See Iowa
    Rs. Civ. P. 1.932-.934. A general verdict is a verdict in which the jury
    only makes a finding in favor of one party over the other party.       See
    Black’s Law Dictionary 1555 (7th ed. 1999) (defining “general verdict” as
    “[a] verdict by which the jury finds in favor of one party or the other, as
    opposed to resolving specific fact questions”). A special verdict consists
    entirely of questions that elicit special written answers to resolve the
    material issues of fact in the case, and the court then enters judgment
    based on the findings made by the jury. Pexa v. Auto Owners Ins. Co.,
    
    686 N.W.2d 150
    , 160 (Iowa 2004); see Black’s Law Dictionary 1555
    (defining “special verdict” as “[a] verdict that gives a written finding on
    each issue, leaving the application of law to the judge”); see also
    McConnell   v.   ALCOA,   
    367 N.W.2d 245
    ,   246    n.1   (Iowa   1985)
    (distinguishing between special verdicts and special interrogatories
    accompanying general verdicts). The answers by the jury become special
    written findings of fact. 
    McConnell, 367 N.W.2d at 246
    n.1. No general
    11
    verdict is entered by the jury, and the jury does not consider the effect of
    its special findings.   See 
    Pexa, 686 N.W.2d at 161
    (stating that when
    special verdicts are submitted, “ ‘it is wholly unnecessary and is
    generally improper for the jury to be concerned with the effect of its
    special findings’ ” (quoting Poyzer v. McGraw, 
    360 N.W.2d 748
    , 753 (Iowa
    1985))). Instead, the court enters judgment by applying the law to the
    findings. 
    Id. at 160;
    Black’s Law Dictionary 1555. A special verdict is
    normally used in cases involving complicated legal principles to help
    simplify the resolution of the case and to force the jury to focus on the
    important issues in the case. 
    Poyzer, 360 N.W.2d at 753
    .
    A general verdict may be supplemented with written interrogatories
    that cover certain issues of fact upon which the verdict is based. Iowa R.
    Civ. P. 1.934.    These are called “special interrogatories.”   Black’s Law
    Dictionary 825; see also 
    McConnell, 367 N.W.2d at 246
    (“In order to avoid
    confusion, a special verdict should not be called an interrogatory.”). Like
    a special verdict, special interrogatories help to focus the jury on the
    important issues in the case that bear upon the general verdict the jury
    must reach.      See Willametz v. Guida-Seibert Dairy Co., 
    254 A.2d 473
    ,
    476 (Conn. 1968) (“The primary purpose of an interrogatory is to elicit a
    determination of material facts and to furnish the means of testing the
    correctness of the verdict rendered.” (Citation omitted.)); Burmac Metal
    Finishing Co. v. W. Bend Mut. Ins. Co., 
    825 N.E.2d 1246
    , 1259 (Ill. App.
    Ct. 2005) (“ ‘The purpose of a special interrogatory is not to instruct the
    jury, but to act as a check on its verdict.’           Specifically, special
    interrogatories are used to test the general verdict against the jury’s
    conclusions as to the ultimate controlling facts.” (Citation omitted.));
    Freeman v. Norfolk & W. Ry., 
    635 N.E.2d 310
    , 313 (Ohio 1994) (“The
    purpose of an interrogatory is to ‘test the jury’s thinking in resolving an
    12
    ultimate issue so as not to conflict with its verdict.’ ” (Citation omitted.)).
    Both special verdicts and special interrogatories submitted with a
    general verdict are findings by the jury that the court uses to enter
    judgment—like pieces of a puzzle. In the case of special verdicts, the jury
    merely gives the court the pieces, and the court assembles the puzzle
    and enters judgment.       In the case of a general verdict with special
    interrogatories, the jury assembles the puzzle to complete the picture. If
    all the pieces fit together correctly, the court enters judgment. However,
    if the pieces do not fit together correctly, the court can see what went
    wrong and attempt to fix the puzzle instead of starting over again with a
    new jury.    Each puzzle piece, or finding, must be supported by the
    evidence presented.     Cowan v. Flannery, 
    461 N.W.2d 155
    , 158 (Iowa
    1990).      Furthermore,    the   findings   made    cannot    be   internally
    inconsistent.   See 
    Dutcher, 221 N.W.2d at 761
    (“[W]hen there is an
    irreconcilable conflict between the general verdict and special findings
    the latter must prevail and the general verdict cannot stand.”); 89 C.J.S.
    Trial § 992, at 603 (2001) (stating that when findings in special verdicts
    “are utterly and irreconcilably inconsistent with, or repugnant to, each
    other, they neutralize, nullify, or destroy each other”).
    Our rules of civil procedure contemplate instances of inconsistent
    findings by the jury, and specifically address conflicts in answers to
    special interrogatories submitted with a general verdict. Iowa R. Civ. P.
    1.934. If the interrogatory answers are consistent with each other but
    any answer is inconsistent with the general verdict, then the court has
    three options to consider. 
    Id. It may
    send the jury back for additional
    deliberations, enter judgment according to the special interrogatory
    answers, or grant a new trial.      Id.; accord Berghammer v. Smith, 
    185 N.W.2d 226
    , 234 (Iowa 1971) (noting special interrogatories trump the
    13
    general verdict in case of a conflict).       However, if the interrogatory
    answers are inconsistent with each other and any is inconsistent with
    the general verdict, the options of the court are narrowed to two. Iowa R.
    Civ. P. 1.934. The court may either send the jury back for additional
    deliberations or grant a new trial.    
    Id. In this
    instance, the court no
    longer has the option to enter judgment.        This option is not available
    because inconsistent answers constitute inconsistent findings that
    cannot support a judgment. See Bangs v. Pioneer Janitorial of Ames, Inc.,
    
    570 N.W.2d 630
    , 632 (Iowa 1997) (“If a verdict is internally inconsistent
    . . . , and there is no way to determine the jury’s intent, the proper
    remedy is a new trial.” (citing 
    Cowan, 461 N.W.2d at 160
    ; Hoffman v.
    Nat’l Med. Enters., Inc., 
    442 N.W.2d 123
    , 127 (Iowa 1989))); cf. 89 C.J.S.
    Trial § 992, at 603 (stating that when findings in special verdicts “are
    utterly and irreconcilably inconsistent with, or repugnant to, each other,
    they neutralize, nullify, or destroy each other”).
    Although    rule   1.933,   governing    special   verdicts,   does   not
    specifically address the possibility of an internal inconsistency in the
    answers in the special verdict, we recognize that rule 1.934, governing
    special interrogatories supplementing general verdicts, is construed
    together with rule 1.933. See Crookham v. Riley, 
    584 N.W.2d 258
    , 269
    (Iowa 1998) (stating the rules are construed in pari materia, meaning
    “taken together as if they were one law, . . . construed together as though
    they constituted one act” (citing Fitzgerald v. State, 
    220 Iowa 547

    260 N.W. 681
    , 683 (1935))).       Thus, the rules governing inconsistent
    special interrogatory answers would apply to inconsistent answers in a
    special verdict. Both answers constitute special findings in the case and
    must be internally consistent.      If not, the court must either resume
    deliberations or grant a new trial. Iowa R. Civ. P. 1.934. Inconsistent
    14
    answers that constitute special findings cannot support a judgment.
    Our prior cases illustrate this rule. Compare 
    Crookham, 584 N.W.2d at 269
    (when answers to special verdict in malpractice action finding lawyer
    negligent were consistent with each other but inconsistent with a general
    verdict for the lawyer on a counterclaim for unpaid fees, trial court had
    discretion to consider all options including entering judgment for client
    on the counterclaim consistent with the answers to the special verdict),
    and 
    Dutcher, 221 N.W.2d at 762
    (answers to special interrogatories were
    consistent with each other but one was inconsistent with the general
    verdict; court was within its discretion in ordering new trial in lieu of
    other two options of resubmission or entering judgment), with 
    Bangs, 570 N.W.2d at 632
    (answers to special verdict were inconsistent with
    each other (damage itemization 3 awarded $100,000 for past and future
    pain and suffering but $0 for medical expenses); new trial was required
    because there was no way to determine whether jurors denied medical
    expenses because they thought they were paid by a third party or
    whether they compromised on liability by reducing total damages
    awarded), and Guzman v. Des Moines Hotel Partners, Ltd., 
    489 N.W.2d 7
    ,
    12 (Iowa 1982) (stating the court properly resubmitted the case to the
    jury when answers in special verdict were internally inconsistent in that
    the jury found negligence, but no proximate cause and then proceeded
    further to award damages), and

    medical expenses but $0 for pain and suffering)), and Shewry v. Heuer,

    15
    discretion by failing to order a new trial when special verdicts were
    internally inconsistent (awarded medical expenses but no pain and
    suffering)). But see Berhow v. Kroack, 
    195 N.W.2d 379
    , 384 (Iowa 1972)
    (trial court properly granted judgment notwithstanding the verdict when
    answers to special interrogatories were internally inconsistent and
    inconsistent with general verdict).
    The parties maintain that the verdict in this case constituted a
    special verdict, and they dispute how the rules apply to resolve the case.
    While the verdict did not actually require the jury to enter a general
    verdict, it did require the jury to determine the total recoverable damages
    by subtracting the amount of damages CPT failed to mitigate from the
    total damages sustained from the breach of the contract. This is not a
    process normally associated with a special verdict.         See 
    Pexa, 686 N.W.2d at 160
    (stating that in a special verdict, “the jury resolves
    pertinent factual issues pursuant to the court’s instructions, and the
    trial court enters the general verdict ‘by applying the applicable law to
    the jury’s factual determinations’ ” (citation omitted; emphasis added)).
    Nevertheless, the rules governing inconsistent answers in a verdict are
    the same. Whether the answers are in response to special interrogatories
    or are answers to a special verdict, if they are inconsistent, then the
    court must either resume deliberations or grant a new trial. Iowa R. Civ.
    P. 1.934; see 
    Crookham, 584 N.W.2d at 269
    (stating rules 1.933 and
    1.934 are construed in pari materia).
    It is fundamental that these principles only apply to inconsistent
    verdicts or inconsistent answers within the verdict. If the answers are
    not inconsistent, the court, of course, is permitted to enter judgment
    consistent with the answers. Iowa R. Civ. P. 1.934. Thus, the first step
    in the application of the rule is to determine if an inconsistency exists.
    16
    We have said that a verdict is not inconsistent if it can be
    harmonized in a reasonable manner consistent with the jury instructions
    and the evidence in the case, including fair inferences drawn from the
    evidence. 
    Hoffman, 442 N.W.2d at 126-27
    . The test recognizes that the
    determination of whether two answers are inconsistent requires the court
    to consider how the jury could have viewed the evidence and how that
    view of the evidence fits into the requirements of the instructions or the
    law applicable to the case. See 66 C.J.S. New Trial § 82, at 172 (1998)
    (“In determining whether findings or answers are inconsistent or
    irreconcilable so as to warrant a new trial, the findings or answers are to
    be construed in light of the surrounding circumstances and in
    connection with the pleadings, instructions and issues submitted.”).
    Ultimately, two answers are not inconsistent if they can be harmonized
    under the evidence and the instructions. See, e.g., Foggia v. Des Moines
    Bowl-O-Mat, Inc., 
    543 N.W.2d 889
    , 892 (Iowa 1996) (jury’s award of
    damages for pain and suffering but no award of damages for medical
    expenses was not inconsistent because the jury could have “found none
    of his medical expenses were caused by the fall at issue”); Brant v.
    Bockholt, 
    532 N.W.2d 801
    , 805 (Iowa 1995) (jury’s award of “$31,000
    damage for future medical expenses for treatment of facial scarring” and
    no damages for loss of function of the body was not inconsistent because
    “plaintiff presented no evidence of functional impairment due to facial
    scarring,” and the jury could have included the damages on this item
    with the umbrella of future pain and suffering).     Thus, the process of
    determining whether answers are inconsistent focuses on the evidence
    and the law, and the court must decide if the two answers at issue can
    be harmonized in light of the evidence and the law. When, under this
    analysis, two answers or findings by the jury would compel the rendition
    17
    of different judgments, the answers are inconsistent.     89 C.J.S. Trials
    § 993, at 605-06; see 
    id. § 992,
    at 604 (“The test to determine if conflict
    between jury questions is irreconcilable is whether one answer would
    establish a cause of action while the other answer would destroy it, or
    whether taking one finding alone a judgment should be entered in favor
    of the plaintiff and taking the other finding alone a judgment should be
    rendered for the defendant.”).
    This process of determining whether answers are inconsistent by
    attempting to harmonize the answers with the evidence and the law is
    separate from the process of reconciling two answers determined to be
    inconsistent.   In this case, for example, there was evidence to either
    support or reject the claim of failure to mitigate damages as instructed
    by the trial court. However, under the instructions, the jury could not
    find that CPT did not fail to mitigate damages and then reduce damages
    based on the failure to mitigate.      The two findings by the jury would
    compel different judgments.       Thus, the two answers by the jury were
    clearly inconsistent with the instructions.      Nevertheless, the district
    court did not proceed to apply the rules governing inconsistencies in a
    verdict, but proceeded to harmonize the inconsistent answers by
    concluding that the jury did not intend to answer “no” to question 4, but
    intended to answer “yes.”        In this way, the district court found the
    answers were consistent and entered judgment.        However, the district
    court went too far under the guise of harmonizing purportedly
    inconsistent answers and engaged in a process of reconciliation not
    available when two special findings are inconsistent with each other, and
    both are supported by evidence.        See Iowa R. Civ. P. 1.934 (“If the
    answers are inconsistent with each other, . . . the court shall not order
    judgment, but either send the jury back or order a new trial.”).
    18
    A court may reform a verdict by correcting a mistake. Ostrem v.
    State Farm Mut. Auto. Ins. Co., 
    666 N.W.2d 544
    , 546 (Iowa 2003). We
    recognize that “verdicts are to be liberally construed to give effect to the
    intention of the jury and to harmonize verdicts if it is possible to do so.”
    
    Hoffman, 442 N.W.2d at 126
    (citations omitted). However, this power is
    very limited and only permits the court to correct mistakes or errors in
    the verdict that are technical or ministerial in nature.      
    Ostrem, 666 N.W.2d at 546
    .     A judge cannot exercise the power to substitute its
    judgment for the judgment of the jury. 
    Id. In this
    case, the district court may have uncovered a very logical
    explanation for the inconsistent answers.           Yet, this explanation
    necessarily involved some degree of speculation. It involved speculation
    because there was evidence that would have permitted the jury to either
    accept or reject the mitigation-of-damages claim. Verdicts can only be
    reformed when the change “clearly and definitely expresses the jury’s
    intentions.” 
    Id. When two
    answers in a verdict are both supported by
    substantial evidence but are inconsistent under the instructions, a court
    may not attempt to reconcile the inconsistency and enter a judgment by
    correcting the inconsistency to conform to the intent of the jury because
    the two conflicting views of the evidence would necessarily produce some
    speculation about the intent of the jury. See Ex parte Alfa Mut. Ins. Co.,
    
    799 So. 2d 957
    , 962 (Ala. 2001) (“ ‘Where a jury verdict is the result of
    confusion or is inconsistent in law, the trial court should grant a new
    trial; a new trial is necessary because, once the jury is dismissed, any
    attempt to reconcile the inconsistencies in a verdict must be based on
    mere speculation about the jury’s intent.’ ” (quoting City of Bessemer v.
    Foreman, 
    678 So. 2d 759
    , 760 (Ala. 1996))).
    19
    The answers in the verdict in this case were internally inconsistent
    as a matter of law.         The district court had no power to correct the
    inconsistency in the verdict because there was substantial evidence to
    support both answers. Thus, the court had no power to enter judgment
    following discharge of the jury, but was required (because the jury had
    been discharged) to grant a new trial as a matter of law. It was the only
    remedy available to the court to exercise under the circumstances.
    IV.    Evidentiary Ruling
    Because this case must be remanded for a new trial, we proceed to
    address the disputed evidentiary ruling by the district court because it is
    likely to arise on retrial.         See McElroy v. State, 
    703 N.W.2d 385
    , 392
    (Iowa 2005) (stating we may consider issues likely to arise on retrial
    (citing McElroy v. State, 
    637 N.W.2d 488
    , 501-02 (Iowa 2001); Gacke v.
    Pork Xtra, L.L.C., 
    684 N.W.2d 168
    , 184-85 (Iowa 2004); Greenwood v.
    Mitchell, 
    621 N.W.2d 200
    , 207-08 (Iowa 2001))). As previously noted, the
    district court excluded evidence of the terms of the 2001 contract
    between John Deere and CPT, ruling it was not relevant to the
    interpretation of the 1996 contract. We must decide whether this was an
    abuse of discretion.       See State v. Sinclair, 
    582 N.W.2d 762
    , 764 (Iowa
    1998) (“This court reviews the trial court's decision on the relevancy of
    evidence for an abuse of discretion.”).
    One issue the jury had to decide in resolving the contract claim in
    this case was whether paragraph 3(c) 4 of the 1996 contract applied to
    4Paragraph   3(c) provided:
    If [CPT] discontinues or adds any service covered by this
    Agreement, [CPT] shall notify [John Deere] prior to discontinuance or
    addition, and the rate set forth in [the ancillary rate structure] shall be
    adjusted by agreement of both parties. [John Deere] shall review, at the
    time of the addition or deletion, the need in the network for the service to
    appropriately handle access. If the need for the addition of the service
    20
    services provided at a new location. CPT sought to introduce the 2001
    contract because it contended paragraph 12 of that contract, which
    specifically addressed the situation of opening a new office, 5 showed that
    John Deere did not intend paragraph 3(c) of the old contract to cover the
    situation of addition of a new office. Rather, CPT claimed paragraph 3(c)
    only applied to the situation of addition of particular services at existing
    locations.
    Generally, contracts are interpreted based on the language within
    the four corners of the document. See Smidt v. Porter, 
    695 N.W.2d 9
    ,
    21 (Iowa 2005) (“It is a fundamental and well-settled rule that when a
    contract is not ambiguous, we must simply interpret it as written.” (citing
    State Pub. Defender v. Iowa Dist. Ct., 
    594 N.W.2d 34
    , 37 (Iowa 1999);
    Rogers v. Md. Cas. Co., 
    252 Iowa 1096
    , 1098-99, 
    109 N.W.2d 435
    , 437
    (1961))). However, when the language is ambiguous, we must engage in
    a process of interpretation to search for “the meanings attached by each
    party at the time the contract was made.”                   E. Allan Farnsworth,
    Contracts § 7.9, at 458 (3d ed. 1999).           To reveal this intent, extrinsic
    evidence is admissible “ ‘when it sheds light on the situation of the
    parties, antecedent negotiations, the attendant circumstances, and the
    objects they were striving to attain.’ ” Dickson v. Hubbell Realty Co., 
    567 N.W.2d 427
    , 430 (Iowa 1997) (quoting Kroblin v. RDR Motels, Inc., 347
    ________________________
    exists, [CPT] shall comply with [John Deere’s] credentialing requirements
    for that new service.
    5   Paragraph 12 provided:
    [CPT] understands and agrees that if [CPT] opens or enters into
    business in another location, that does not cause automatic inclusion
    into the products listed on [the product participation matrix/fee
    schedule] for services provided at that location. [CPT] must notify [John
    Deere] of the new location and [John Deere] at its sole discretion will
    determine the need of entering into a contractual relationship for the new
    location.
    
    21 N.W.2d 430
    , 433 (Iowa 1984)). However, the 2001 contract in this case
    does little to shed light on the situation of the parties or any attendant
    circumstances in 1996—the time relevant to the interpretation of the
    governing contract.   Id.; see also 17A Am. Jur. 2d Contracts § 346, at
    333-34 (2004) (“The intention, with which the law is concerned in
    construing and giving effect to a contract, is that of the parties at the
    time of entering into the contract, regardless of any events occurring
    afterward, at least if such subsequent events were not reasonably within
    the contemplation of the parties when the contract was made.”).         A
    specific clause placed in the 2001 contract by the parties concerning new
    offices does not show the intent of the parties in 1996 regarding the
    application of paragraph 3(c) to new offices. Thus, the 2001 contract was
    not relevant to the interpretation of the 1996 contract. It did not make
    either of the competing meanings asserted by the parties more likely or
    less likely than it would be without the evidence.     See Iowa R. Evid.
    5.401 (“ ‘Relevant evidence’ means evidence having any tendency to
    make the existence of any fact that is of consequence to the
    determination of the action more probable or less probable than it would
    be without the evidence.”).     We find no abuse of discretion in its
    exclusion.
    V.     Conclusion
    We vacate the decision of the court of appeals, reverse the
    judgment of the district court, and remand for a new trial.      To avoid
    repetition of this resource-wasting result, we repeat out prior admonition
    that “[t]he trial court should not discharge the jury until it determines
    the special verdict is consistent and supported by evidence.”     
    Cowan, 461 N.W.2d at 160
    ; see also 75B Am. Jur. 2d Trial § 1854, at 595 (1992)

    (“Ordinarily, when a jury returns inconsistent or incomplete answers to a
    special verdict, it is preferable to send the jury back for further
    deliberation.”).
    DECISION OF COURT OF APPEALS VACATED; DISTRICT
    COURT JUDGMENT REVERSED AND REMANDED.
