Directions: Read the passage/argument and answer the question that follows it.

Though the number of cycle owners in China is increasing by leaps and bounds, yet very few owners make real use of their equipment. For instance, last year more than 100 million bicycles were sold, but not more than 10 million owners cycle down to their workplace at least twice a week or use it for physical exercise at least thrice a week.

Which of the following, if true, tends to cast the most doubt on the assertion that very few Chinese make real use of the bicycles they purchase?

If the Chinese are guilty of exaggerating about bicycle use, it tends to further support the author's contention and is therefore the opposite of what we are trying to locate. Hence, option (1) is wrong here. Option (4) is irrelevant for it talks of another mode of transport, which is not the focus of discussion. Option (5) creates a scenario of an accident being responsible for lesser use of bicycle in future. In a way, it discusses possible reasons for lesser bicycle use by the Chinese. Option (2) is again irrelevant here as it talks of the use of bicycle for shopping, while the author equates the use of bicycling with exercise and going to office. Option (3) is the best one for it points out a major flaw in the author's reasoning because it highlights other possible uses which the bicycles can be put to by the Chinese, thereby negating the hypothesis that not much real use of bicycles takes place.
