og 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. inappropriate

(B) Joggers often exaggerate the frequency with which they jog in surveys designed to elicit such information. inappropriate

(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. inappropriate

(E) Joggers who jog more than once a week are often active participants in other sports as well. inappropriate

答案：C

我觉得D虽然说了purchase其他的鞋，但并没说它的use情况，所以inappropriate

不太清楚OG11对(D)项的解释, OG11说these consumers could be among the 45% who are conceded by the argument to jog more frequently than pnce a year.而我觉得这些人是没有被包含在这45%中的.因为题干说在17%的买了慢跑鞋的人中,仅有45%的人一年慢跑一次,而(D)说经常慢跑的人买的不是慢跑鞋,既然买的不是慢跑鞋当然就没有被算在45%中了.
