 Most consumers do not get much use out of the sports equipment they purchase. For example, 17 percent of the adults in the United States own jogging shoes, but only 45 percent of the owners jog more than once a yea, and only 17 percent jog more than once a week.

Which of the following, if true, casts the 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) In surveys designed to elicit such information, joggers often exaggerate the frequency with which they jog.

(C) Many consumers purchase jogging shoes for use in activities other than jogging.

(D) Consumers who take up jogging often purchase athletic shoes 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.

答案是C，但是D为什么不对呢？

没人回答，自己写解题思路。

两个选项看起来都像，选最有关的。本题claim是most consumers，而D选项说得是consumers who take up jogging，不能代表most consumers；C中many consumers更接近most consumers，所以选C。

D對argument沒有起任何作用...
用一個比較誇張的example:
全地球人都會jogging, 而它們都買了一雙多功能shoes, 又可用來jogging, 又可用來打basketball, soccer, etc.
可是你不能推出"全地球人都會常用他們的shoes"
==========================================
同樣思路, D不能推出"人都會不會常用他們的shoes"

谢谢楼上解释。

可是选项C：Many consumers purchase jogging shoes for use in activities other than jogging.

许多人买jogging鞋作其它用途，也不能推出人们就常用这个鞋子啊。

我觉得主要是看怎么理解"use"吧，因为例子中的jogging shoes只考虑用到jogging,考虑的范围太狭窄，只要提出还可以用到其他的用途就可以weaken由那个例子得出的结论

"Consumers who take up jogging often purchase athletic shoes that can be used in other sports. ", 这里是“can be used"并不是"will be used, or is using"，并不能推出买了athletic shoes就用在了other sports.

OG对D的解释是这些买了运动鞋的消费者已经被算在45%的owner里面了。

呵呵。感觉有点牵强。
