65.   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.

大牛请看下我这样的思路对吗?

结论:大多数的消费者很少使用买来的运动设备 doubt,反对结论,即:大多数消费者并不少

使用买来的运动设备.

(A)使用设备易受伤,因此减少使用,为加强

(C)消费者把买来的设备(慢跑的鞋子)用到了活动中,而非慢跑中,说明还是在经常使用

(D)结论说"use",与"phrchase"无关

(E)结论说"use",与"是否是active participants "无关

以上解释有问题吗? B怎么解释?  谢谢NN们的指点!

A.六个月属于新概念

B如果夸大运动频率的话，那equipment使用的应该更少，而不是更多，显然不doubt

C正解

D买了其他运动鞋也属于运动设备中啊

E明显不对啊～但说不出来原因，呵呵

个人观点哦～
