135. In a new police 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 be most important to answer in evaluating that conclusion? (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? (C) Are cars in neighborhoods that are actively participating in the program sometimes stolen during daylight hours? (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? (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? ans A 想請問一下這一題的D ,當初就在猶豫要選A還是D 我想法是如果車主在一點到五點開車 會被警察騷擾 那就表示此program有效 如果都沒有警方來盤查表示不是這個program造成失竊率下降 這樣看起來D選項也不錯 請問A選項比較好是因為? 先謝謝回答~~ --
