-1-1-21If the city council institutes new parking regulations, city revenues will surely increase, since studies have conclusively shown that, if such parking regulations are put into effect, there is an increase in parking violations, and an increase in parking violations will result in a greater number of parking fines collected.

21. Which one of the following is closest, in terms of its logical features, to the reasoning used in the argument above?
(A) Last year’s increase in revenues can be easily explained. That was the year the city council instituted new parking regulations. No doubt the new law brought with it an increase in the number of parking violations.
(B) If taxes were increased, this act would naturally result in increased revenues for the city, and increased revenues would make some desirable social programs possible. So, if taxes were increased, some desirable social programs would become possible.
(C) Henry says that, if the city council goes into closed session, an important matter of personnel policy is being discussed. However, no personnel matters were discussed at the council meeting, so if Henry is right, the council did not go into closed session.
(D) All cars parked on the north side of the street were ticketed last night, and the same cars were towed away this morning. So beware a car ticketed in this city also gets towed away.
(E) Allen says that, if the city council institutes new parking regulations, it is unlikely that revenues for the city will increase. If Allen is right, then the parking regulation plan should not be instituted.

请问本题的logic feature是什么？ 这样的题怎么入手做？ 我找不到门道阿！

本题的logic feature是: 在"前提"和"结论"间通过因果关系来"搭桥".
