First comment - not sure if this is correct, but I arrived to the correct answer with this method

­Some large European cities, such as Paris and Barcelona, have implemented bicycle sharing programs that allow people, for a small fee, to obtain a bike at any of hundreds of locations and drop it off near their destination. Currently, most large U.S. cities face congestion with cars and taxis, have few bicycle lanes, and discourage the locking of bicycles to poles and fences. Therefore, until the culture of cities becomes less hostile to bicyclists, a wide scale program will not be a viable form of alternative transportation.

Premise: most large cities face congestion, European cities have bike promos that solves hits issue

Argument: The culture of cities needs to become less hostile to bicyclists for a wide scale program

Which of the following would it be most useful to determine in evaluating the argument?

(A) Whether an sharp increase in the number of bicyclists in U.S. cities would change attitudes toward bicyclists
Assuming: we had this answer - yes this would influence change the argument

(B) Whether U.S. who drive cars know how to operate bicycles
Assuming we had this answer: - It wouldn't support the argument
(C) Whether major U.S. cities have plans to expand the availability of bicycle lanes in downtown areas
Assuming we had this answer: - It wouldn't support the argument since the argument is with sentiment and not city development
(D) Whether the number of people interested in traveling by bicycle is greater in U.S. than in Europe
Assuming we had this answer: - It wouldn't support the argument
(E) Whether small U.S. cities are more friendly to bicyclists than large U.S. cities
Assuming we had this answer: - maybe due it the question address sentiment, but it still doesn't tell us much
