大全-C-15

15.   Bill: Smoke-detecting fire alarms can save lives. I believe that every apartment in this city should be required by law to be equipped with a smoke detector.

Joe: I disagree with your proposal. Smoke detectors are just as important for safety in private houses as they are in apartment.

From this exchange, it can be inferred that Joe has interpreted Bill’s statement to mean that

(A) the city should be responsible for providing smoke detectors for apartments

(B) residences outside the city should not be equipped with smoke detectors

(C) only apartments should be equipped with smoke detectors

(D) the risk of fire is not as great in private houses as it is in apartments（C）

(E) the rate of death by fire is unusually high in the city in question

哪位牛牛给解释一下这道题到底问的是什么？问J对B的话的理解吗？还是J自己想表达的意思？
