On October 8, 1975, the plaintiff, Maria F. Solimene, was injured while working with an industrial machine manufactured by the defendant, B. Grauel & Co., KG (Grauel). The plaintiff sought damages from Eastern Marking Machine Corporation (Eastern), which, she alleged, distributed the machine to her employer, and from the machine’s manufacturer, Grauel, on the theories of negligent design and breach of warranty. After trial, the jury found that Grauel was negligent and had violated its warranty of merchantability. 2 We granted the defendant’s petition for direct appellate review.
Grauel raises several issues on appeal. First, Grauel argues that its motion for directed verdict or for judgment notwith *792 standing the verdict should have been allowed and judgment entered in its favor on both the negligence and warranty counts because the conduct of the plaintiff’s employer constituted a superseding cause of the plaintiff’s injuries as a matter of law. 3 Grauel further argues that the trial judge abused his discretion by permitting the plaintiff’s expert to testify as to a condition diagnosed only ten days before trial, in violation of a pretrial discovery order. As to the jury instructions and special questions, Grauel contends that the verdicts entered against it, but in favor of Eastern, are inconsistent and must be set aside. In addition, Grauel argues that the special questions were insufficient because they did not specifically refer to the issue of proximate cause. Grauel also argues that the verdicts must be set aside as against the weight of the evidence. Grauel also challenges the amount of damages awarded by the jury. Grauel contends that the trial court erred in declining to order a remittitur because the amount awarded was against the weight of the evidence. Grauel also challenges the judge’s use of a table depicting various interest and inflation rates to support the conclusion that the jury’s award was not so excessive as to require remittitur. Last, Grauel argues that there was insufficient evidence to support recovery for impairment of future earning capacity. We affirm the judgment for the plaintiff.
We summarize the facts. In reviewing the judge’s refusal to direct verdicts for Grauel, we view the evidence in the light most favorable to the plaintiff.
Everett
v.
Bucky Warren, Inc.,
The plaintiff was trapped in the machine for twenty to forty minutes. Several coworkers struggled to move the oscillating arm but were unsuccessful. When the plaintiff’s wrist finally was freed from the machine, her hand immediately became swollen and she was taken to a hospital.
Although the plaintiff was treated and released on the same day, five weeks later, on November 14, 1975, surgery was performed on the plaintiff’s right wrist to relieve symptoms of carpal tunnel syndrome, a condition caused by pressure on a nerve in the hand. The evidence indicated that the plaintiff’s right hand continues to be severely impaired. She has impaired grip strength and continues to suffer from traumatic sympathetic reflex dystrophy, which is characterized by throbbing pain, burning sensation, intermittent swelling, and a feeling of vise-like compression at the wrist.
Nine months after the accident, on July 6,1976, the plaintiff returned to her position at Teledyne. From July, 1976, until January, 1977, the plaintiff operated the same B3/FR that she had operated prior to the accident. In May, 1977, Teledyne transferred her to another job within the company. She has been steadily employed at an increasing salary since her return to work.
The trial began on January 7, 1985, in the Superior Court. At the conclusion of the evidence, the judge submitted the matter to the jury on special questions. See Mass. R. Civ. P. 49 (a),
1.
The motions for directed verdict and judgment notwithstanding the verdict.
At the close of the plaintiff’s case and at the close of all the evidence, Grauel moved for a directed verdict. See Mass. R. Civ. P. 50 (a),
Generally, questions of causation, proximate and intervening, present issues for the jury to decide. See, e.g.,
Michnik-Zilberman
v.
Gordon’s Liquor, Inc.,
Because the employer had owned the B3/FR for nine years and was aware of the particular risks associated with use of the product, Grauel argues that the employer was in a better position than the manufacturer to make the machine safe for its intended use. Whether a third party is in a better position to prevent harm to another is not determinative of the issue of superseding cause.

In
McDonald v. Snelling,
In this case, Grauel designed the product to operate as the plaintiff was using it. There was no evidence that Teledyne modified or altered the machine in any way. Although the employer gave the plaintiff few instructions as to proper use of the B3/FR, the evidence indicates that Grauel did not give Teledyne any warnings or instructions as to proper use of the machine. Thus, Teledyne’s use of this product, as it was intended and without any alterations to the product, is a foreseeable use.
As a general rule, a tortfeasor is liable “for the foreseeable intervening conduct of a third party whether that conduct is negligent or not.”
Correia
v.
Firestone Tire & Rubber Co.,
Grauel also contends that its motion for judgment notwithstanding the verdict should have been granted because the judge improperly speculated that the jury relied on one of the two theories of defect advanced by the plaintiff. Grauel concludes that, because the judge suggested that the jury relied on one of the theories, the judge “implicitly acknowledge^]” *797 that the jury could not properly have found liability based on the other theory of defect. We do not agree with the defendant’s reading of the judge’s findings.
The plaintiff advanced two theories of design defect. The first theory involved the placement of the on/off toggle switch. The plaintiff stated that, just prior to the accident, she had turned the machine off by moving the on/off switch away from her. The plaintiff then “went with [her] arm in back of the base to retrieve” the object that had fallen. After retrieving the object, the plaintiff stated that she brought her arm back and, as she was doing so, her elbow hit the on/off switch, reactivating the machine and trapping her wrist under the oscillating arm. 11 The plaintiff presented expert testimony that there were several alternative designs for the switch, including guards which extend above the level of the toggle switch, recessed switches or push-button switches, which were feasible design alternatives that could have prevented this accident.
The plaintiff’s second theory of defect involved the lack of a guard over the oscillating arm. The plaintiff presented expert testimony that a guard was both possible and feasible at the time this machine was designed. A guard would have prevented the plaintiff’s arm from being trapped by the machine’s oscillating arm.
In ruling on Grauel’s posttrial motions, the judge noted that it was his belief that the verdict was based on the guard theory of defect. The judge further stated that, even if the verdict were based on the switch theory of defect, the evidence showed that if the switch were “recessed, with shoulders,” it could not have been unintentionally activated. Based on these statements, we do not believe, as Grauel contends, that the judge implicitly *798 acknowledged that the jury could not properly impose liability solely on the basis of a switch theory.
The plaintiff has the burden to show that Grauel’s negligence caused her injury. The plaintiff may meet that burden by presenting two possible theories of defect to the jury. “There is no requirement of law that the plaintiff point out the exact way an accident happens.”
McLaughlin
v.
Bernstein,
2. Admission of testimony of new diagnosis. On January 3, 1985, the plaintiff’s medical expert furnished Grauel with a copy of a report of a physical examination of the plaintiff that he had performed during the previous week. The trial commenced on January 7, 1985, only four days after Grauel received a copy of this report. The expert indicated in his report that the plaintiff was suffering from “symptoms and signs of a traumatic sympathetic reflex dystrophy, . . . [which is] a relatively frequent complication of a carpal tunnel syndrome.” Traumatic sympathetic reflex dystrophy was not mentioned in any prior reports.
Grauel moved to limit the testimony of this expert by excluding any evidence of this diagnosis. The judge indicated that he would allow Grauel’s motion unless the plaintiff’s expert were made available for deposition by Grauel. The judge also ruled that, if the plaintiff made her expert available for deposition and Grauel deposed that expert, then Grauel must make its expert available for deposition by the plaintiff. Although the plaintiff made her expert available for deposition, Grauel *799 chose not to take advantage of this opportunity. 13 Therefore, the plaintiff’s expert was permitted to testify as to this new diagnosis at trial.
The conduct and scope of discovery is within the sound discretion of the judge. See, e.g.,
Bishop
v.
Klein,
The judge conditioned the admissibility of the testimony of the plaintiff’s expert as to the new diagnosis on the opportunity of the defendant to depose the expert. Grauel’s choice not to pursue this alternative does not require a conclusion that the testimony as to the diagnosis resulted in unfair surprise. “We must assume [Grauel’s] counsel was prepared to cross-examine all opposing expert medical witnesses on the expectation that they would testify consistent with the theory of [plaintiff’s] case.” Schneider v. Lockheed Aircraft Corp., supra.
3. Special verdict. Grauel challenges the jury’s responses to special questions in two respects. First, Grauel argues that the responses were “hopelessly inconsistent.” Grauel concludes that the proper remedy is a new trial. Second, Grauel asserts that the questions were insufficient because they failed to mention the element of proximate cause. According to Grauel, this omission constitutes prejudicial error. These contentions are without merit.
The judge submitted seven questions to the jury. The first three questions concerned the negligence of Grauel, Eastern, and the plaintiff. The fourth question asked the jury to deter *800 mine the percentage of negligence attributable to each party. The next two questions addressed whether Grauel or Eastern, or both, violated their warranties of merchantability. The final question asked the jury to assess damages.
Because we have explicitly left open the appropriate procedure to be followed under rule 49 (a), we comment briefly on the procedure to be followed. See
International Fidelity Ins. Co.
v.
Wilson,
Under rule 49 (a), the jurors return answers to each question or each issue submitted to them. The jurors do not return a general verdict. The answers to the questions or issues submitted are considered a special verdict consisting of “a statement of facts the jury have found from which the judge determines the appropriate judgment.”
Commonwealth
v.
Licciardi,
Pursuant to his duty to harmonize the jury’s answers, the judge noted in his memorandum and order in response to the posttrial motions that Eastern’s defense in part was that it was not the source of the machine purchased by Teledyne. If Eastern *802 were not the source of the machine, Eastern would not be liable to the plaintiff. Thus harmonized, the verdicts are not inconsistent.
As to Grauel’s contention that the questions were deficient without reference to proximate cause, “[t]he nature, scope, and form of special questions submitted to a jury pursuant to Mass. R. Civ. P. 49 (a),

Verdicts against the evidence and the weight of the evidence.
Grauel asked the judge to set aside the verdict for the plaintiff as against the evidence and the weight of the evidence. A motion to set aside a verdict as against the evidence is addressed to the sound discretion of the judge. “It is the right and duty of a judge presiding at the trial of a civil case to set aside the verdict of the jury when in his judgment it is so greatly against the weight of the evidence as to induce in his mind the strong belief that it was not due to a careful consideration of the evidence, but that it was the product of bias, misapprehension or prejudice.”
Scannell
v.
Boston Elevated Ry.,
5. Damages. Grauel challenges the damage award on several bases. Grauel asserts that the damages awarded were against *803 the weight of the evidence. Thus, Grauel argues that the judge erred in declining to order a remittitur. Grauel also challenges the judge’s use of a table showing a range of inflation and interest rates to support the conclusion that the jury’s award was not excessive. Finally, Grauel contends that there was insufficient evidence to support recovery for impairment of future earning capacity.
A challenge to the damages awarded as against the weight of the evidence generally is a matter within the judge’s discretion. As the judge here recognized, “a judge has no right to set aside a verdict merely because he himself would have assessed the damages in a different amount.”
Bartley
v.
Phillips,
Grauel argued that the award was excessive if analyzed as to the amount the plaintiff could receive on a weekly basis. The judge appears to have used a computer to analyze Grauel’s claim. He constructed a table to show the range of weekly and yearly amounts that the plaintiff could receive from her award, given various combinations of interest and inflation rates. Grauel argues that .it has not had an opportunity to explore the basis of the document and that the court’s construction and use of this table represents an effort to take judicial notice of the information contained in it. We do not agree. The judge simply analyzed the claim of excessive damages by using mathematical calculations to determine if the award were excessive. The judge obviously gave Grauel’s claim serious consideration and the table illustrates the care with which the judge analyzed Grauel’s assertion concerning the award. 15 The judge *804 denied Granel’s motion for new trial because he concluded that the jury reached the verdict “honestly and fairly” considering, among other things, the evidence of permanent pain and disability.
As to Grauel’s last claim of error, the judge instructed the jury that the plaintiff was entitled to an award which should include, among other things, the extent by which her ability to earn has been reduced. Grauel objected during the plaintiff’s closing statement to the argument concerning loss of earning capacity on the ground that there was no evidence of lost earning capacity. The judge stated that he intended to permit the jury to consider the subject of lost earning capacity
16
on the basis of their common knowledge. The judge instructed the jury on loss of earning capacity. Grauel did not object to that instruction, thus this claim is not before us. See Mass. R. Civ. P. 51 (b),
Judgment affirmed.
Notes
The jury also found that Eastern was not negligent and did not violate its warranty of merchantability. The plaintiff did not appeal from the entry of judgment for Eastern.
Grauel also contends that the trial judge based his denial of the motion for judgment n.o.v. on purely speculative grounds.
Further evidence of the operation of the machine will be presented as it becomes relevant to the specific claims of error. See infra at 797-798.
The jury determined the plaintiff’s damages on the negligence claim to be $275,000, plus interest. After reduction of that amount by the percentage of the plaintiff’s negligence, judgment entered for the plaintiff on this claim in the amount of $261,250, plus interest.
After entry of judgment, the judge ordered that the plaintiff may enforce judgment on either the warranty or the negligence claim, but not on both claims.
Although the plaintiff’s husband brought a loss of consortium claim, he consented to its dismissal on January 16, 1985.
Restatement (Second) of Torts § 452 (1965) provides: “(1) Except as stated in Subsection (2), the failure of a third person to act to prevent harm to another threatened by the actor’s negligent conduct is not a superseding cause of such harm. (2) Where, because of lapse of time or otherwise, the duty to prevent harm to another threatened by the actor’s negligent conduct is found to have shifted from the actor to a third person, the failure of the third person to prevent such harm is a superseding cause.”
We note that the judge quoted § 452(2) directly in his charge to the jury. Grauel argues that comment f to § 452 requires the issue of superseding cause to be decided by the judge. In relevant part, this comment states that “the circumstances may be such that the court will find that all duty and responsibility for the prevention of the harm has passed to the third person.” Id. at § 452 comment f. In this case, the judge did not so find and therefore he correctly left the issue to the jury to decide.
Restatement (Second) of Torts, supra at § 440, defines superseding cause as “an act of a third person or other force which by its intervention prevents the actor from being liable for harm to another which his antecedent negligence is a substantial factor in bringing about.”
Grauel argues that the failure of the judge to mention the plaintiff’s employer by name in the superseding cause charge constituted prejudicial error. A judge is not required to instruct the jury in the precise form requested by counsel so long as the charge is accurate and complete. Our examination of the whole charge reveals that the judge provided thorough instructions on all the necessary issues. Leech v.
Ebers,
The evidence was conflicting as to whether the switch operated as the plaintiff testified. In Granel’s original answers to interrogatories, Grauel stated that the toggle switch operated as the plaintiff had stated, with the switch pointed away from the operator in the “off’ position. Grauel filed an amended answer to this interrogatory stating that the switch was mounted so that, in the “on” position, the switch was away from the operator and in the “off’ position, the toggle switch was toward the operator. At trial, both answers were read to the jury.
The only other possible explanation for this accident was that the plaintiff did not shut off the machine and reached into the operating machine to retrieve the dropped object. It was the jury’s finding that the plaintiff was only five per cent negligent, while Grauel was ninety-five per cent negligent. Thus, the jury appear to have rejected that defense.
Grauel did not depose the plaintiff’s expert because it did not want the plaintiff to obtain “belated discovery of Grauel’s medical expert.”
When a case is submitted to the jury under rule 49 (b) of the Massachusetts Rules of Civil Procedure,
If there is total inconsistency, meaning that the answers are inconsistent with each other and inconsistent with the general verdict, “judgment shall not be entered, but the court shall return the jury for further consideration of its answers and verdict or shall order a new trial.” Mass. R. Civ. P. 49 (b).
In deciding whether the damages were excessive, the judge was not limited to Grauel’s analysis.
The plaintiff in a personal injury action is entitled to recover damages for impairment of earning capacity.
