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.

17% percent of the adults in the United States own jogging shoes, (of 100 people, 17 have jogging shoes)
but only forty-five percent of the owners jog more than once a year, (9 of these 17 jog once a year or not at all)
and only seventeen percent jog more than once a week (3 people jog regularly)
Conclusion: Most consumers do not get much use out of the sports equipment they purchase.
We conclude that consumers don't get USE out of their purchases. But the example only discusses 'use for that particular sport'. Option (C) says that consumers get non-jogging use out of their jogging shoes. This weakens our conclusion. We cannot conclude that consumers do not get use. We may be able to conclude that they do not get use for that particular sport.
Note that the argument discusses people who buy jogging shoes - that 45% of them jog more than once a year and only 17% jog more than once a week.
It talks about consumers who buy sports equipment and how they use the equipment.
(A) Joggers are most susceptible to sports injuries during the first six months in which they jog.
Irrelevant.
(B) Joggers often exaggerate the frequency with which they jog in surveys designed to elicit such information.
This just says that the 'use for jogging' numbers are actually exaggerated. So the use is even lower and our conclusion is good.
(C) Many consumers purchase jogging shoes for use in activities other than jogging.
Correct. It tells us that we cannot conclude about generic "USE" based on our example. People use jogging shoes for other things so they do get use out of it even though they may not jog.
(D) Consumers who take up jogging often purchase an athletic shoe that can be used in other sports.
Irrelevant. We are not talking about consumers who jog and purchase other shoes. Those people are irrelevant to us.
We are talking about consumers who purchase jogging shoes. Our entire argument revolves around a different set of people.
(E) Joggers who jog more than once a week are often active participants in other sports as well.
Irrelevant. We don't care about the set of joggers who jog more than once a week. We don't know how many of them buy jogging shoes. They do not represent our set of concern.
Answer (C)
