Physician: There were approximately 83,400 trampoline-related injuries last year. This suggests that trampolines are quite dangerous and should therefore be used only under professional supervision.
Trampoline enthusiast: I disagree. In the past ten years sales of home trampolines have increased much more than trampoline-related injuries have: 260 percent in sales compared with 154 percent in injuries. Every exercise activity carries risks, even when carried out under professional supervision.
The dialogue provides the most support for the claim that the physician and the trampoline enthusiast disagree over whether
(A) trampolines cause injuries to a significant number of people using them -
P: Definitely agrees to this fact
TE: Agrees. He/She simply mentions that the injuries/sales percentage have decreased over years
(B) home trampolines are the main source of trampoline-related injuries
Both do not comment on "main-source"
(C) the rate of trampoline-related injuries, in terms of the number of injuries per trampoline user, is declining
P: He/she does not comment on the number of injuries/user. Simply states that there are considerable injuries because of the use of trampoline
TE: Agrees to this fact
(D) professional supervision of trampoline use tends to reduce the number of trampoline-related injuries
P: Comments that the used is advised. Does not comment on the injuries rate in presence of supervision
TE: Similar to P, does not comment on the injuries rate in presence of supervision
(E) trampoline use is an activity that warrants mandatory professional supervision
P: Mentions that the high number of accidents dictates that trampoline use requires supervision
TE: Disagrees by mentioning that the data mentioned does not provide the complete picture.
Answer: E
