252. (Three out of every four automobile owners in the United States also own a bicycle).
(A)    Three out of every four automobile owners in the United States also own a bicycle.

(D)    In the United States, three out of every four automobile owners owns bicycles.
(E)    Out of every four owners of automobiles in the United States, bicycles are also owned by three.
正确答案是Ａ
Ａ的意思是四个人当中有三个人拥有一辆脚踏车。感觉不是很合理啊。
我想原句的意思应该是四个拥有汽车的人当中，三个人也同时拥有自行车，所以虽然Ｃ使用的被动语态，但是道理上更说得过去啊？
