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. C

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

请问D为什么不对，D说明消费者买an athletic shoe既可以Jogging, 也可以做other sports 啊，也反对了“ Most consumers do not get much use out of the sports equipment they purchase.”，谢谢
