Stimulus Summary

P: The large number of trampoline injuries last year shows they’re dangerous.
TE: Trampoline sales have increased faster than injuries, and all exercise carries risk, so trampolines aren’t dangerous and can be used without supervision.

Answer Anticipation

The Physician starts her argument by bringing up the large number of trampoline injuries. And while the trampoline enthusiast brings up trampoline injuries, he only does so in discussing the growth rate of them - so we can’t commit them to disagreeing over any of these statistics.
However, the Physician uses the number of injuries to justify a two-part conclusion - trampolining is quite dangerous, and it should only be used under professional supervision.
The Trampoline Enthusiast disagrees. He concedes that there is some danger, but not that they’re disproportionately dangerous compared to all exercise, any of which carries risks. He additionally states that professional supervision can’t eliminate risk.
It’s this conclusion they disagree over - and the rationale behind the Physician’s conclusion based on the number of injuries - so an answer should highlight something about that.

Answer choices

  1. A
    trampolines cause injuries to Remaining source text redacted.
    Why choice A is not credited
    The Physician discusses the large number of injuries, so she’d agree with this answer. But the Enthusiast doesn’t disagree that there are injuries - after all, all exercise carries risk. Therefore, this isn’t necessarily a point of disagreement between the two speakers.
  2. B
    home trampolines are the Remaining source text redacted.
    Why choice B is not credited
    Neither speaker compares home trampoline-related injuries to overall trampoline injuries, so this answer is out of scope.
  3. C
    the rate of trampoline–related Remaining source text redacted.
    Why choice C is not credited
    The Enthusiast’s statements might allow this inference, but the Physician only discusses the total number of injuries, not the number of trampoline users, so she doesn’t have a clear opinion on this answer.
  4. D
    professional supervision of trampoline Remaining source text redacted.
    Why choice D is not credited
    The Physician implies this by recommending trampoline use only under professional supervision. However, the Enthusiast doesn’t necessarily disagree, instead focusing on how risky exercise can be even under professional supervision. In other words, he might agree that supervision lowers the injury rate while not eliminating it.
  5. E
    trampoline use is an Remaining source text redacted.
    Why choice E matches the stem
    The Physician calls for professional supervision of trampoline use, so she agrees with this answer. The Enthusiast disagrees, stating that all exercise is risky even under professional supervision, and injuries are increasing slower than trampoline use. This is the point at issue between them!
