标题: 大全-20-15

Is there anybody who can explain why choice B is the best answer? Thank you.

15. In the United States, vacationers account for more than half of all visitors to what are technically called “pure aquariums” but for fewer than one quarter of all visitors to zoos, which usually include a “zoo aquarium” of relatively modest scope.

Which of the following, if true, most helps to account for the difference described above between visitors to zoos and visitors to pure aquariums?

(A) In cities that have both a zoo and a pure aquarium, local residents are twice as likely to visit the aquarium as they are to visit the zoo.

(B) Virtually all large metropolitan areas have zoos, whereas only a few large metropolitan areas have pure aquariums.

(C) Over the last ten years, newly constructed pure aquariums have outnumbered newly established zoos by a factor of two to one.

(D) People who visit a zoo in a given year are two times more likely to visit a pure aquarium that year than are people who do not visit a zoo.（B）

(E) The zoo aquariums of zoos that are in the same city as a pure aquarium tend to be smaller than the aquariums of zoos that have no pure aquarium nearby.

ZOOS 既然多数城市都有，就不急者假期去了，平时周末去就得了。PURE DD既然只有几个城市有，本市没有，就赶快趁假期有时间去，平时周末去不了。

Which means we have to use our own judgement or knowledge to finish this question. The knowledge/judgement is that vacationers,rather than visit the nearby “zoo aquarium”on holidaies, tend to visit the P.A. in the big cities other than where they are living.
However, I believe that many people do like to visit a nearby “zoo aquarium”.

I do not wanna make it too complicated. But sometimes really get puzzled with the logic.

Thank you.

这道题很不严密，LSAT是不会考的。该题为解释题，答案是比出来的。
