标题: LSAT-5-4-23

23. In a new program, automobile owners in some neighborhoods whose cars are not normally driven between 1 A.M. and 5 A.M. can display a special decal in the cars’ windows and authorize police to stop the cars during those hours to check the drivers’ licenses. The theft rate for cars bearing such decals is much lower than had been usual for cars in those neighborhoods.

If it is concluded from the statements above that automobile theft has been reduced by the program, which one of the following would it be most important to answer in evaluating that conclusion?

请帮忙翻译一下题干,还有选项A,我选的是D?

(A) Are owners who are cautious enough to join the program taking other special measures to protect their cars against theft?

(B) In how many neighborhoods is the police program operating?

(D) Will owners who have placed decals on their cars’ windows but who find it necessary to drive between 1 A.M. and 5 A.M. be harassed by police?（A）

(E) Are the neighborhoods in which the program has been put into effect a representative cross section of neighborhoods with respect to the types of automobiles owned by residents?

The two things--the programme and the reduction in automobile theft--concurs. But the concurrence doesn't necessarily mean that one causes the other.

只有选项A有可能导致异因同果，继而削弱或支持结论。

其他项都是无关项。
