标题: [求助]OG10th－52
52. Most consumers do not get much use out of the sports equipment they purchase. For example, seventeen
percent of the adults in the United States own jogging shoes, but only forty-five percent of the owners jog more
than once a year, and only seventeen percent jog more than once a week.
Which of the following, if true, casts most doubt on the claim that most consumers get little use out of the
sports equipment they purchase?
(A) Joggers are most susceptible to sports injuries during the first six months in which they jog.
(B) Joggers often exaggerate the frequency with which they jog in surveys designed to elicit such information.
(C) Many consumers purchase jogging shoes for use in activities other than jogging.
(D) Consumers who take up jogging often purchase an athletic shoe that can be used in other sports.
(E) Joggers who jog more than once a week are often active participants in other sports as well.

这道题选B。

对
于D、E的解释，OG上说Because the consumers and joggers mentioned inD and E
respectively are most likely to be among those who frequently use
sports equipment and whose existence the argument concedes,D and E are
inappropreate.这句话没怎么看懂。是不是说，这两类人不是题中讨论所针对的除去45％和17％的那部分对象？
我的做法是：D中所说的集合与原文讨论的集合不同，所以不对。E中没有涉及题目所要讨论的jogging shoes，无关，所以排除。对么？请NN指教，谢谢！
