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.

答案是B，但我觉得D对。谁知道的解释一下。谢谢！

分清vacationer 和visitor 的区别，vacationer 是在度假中的人。而visitor是来参观的人都叫visitor。

B中说了，只有为数不多的大都市才有pure的水族馆，而一般的大城市都有zoo的水族馆。

那么分情形讨论：

1，在那些既没有zoo的，也没有pure的城市的visitor，他们去哪种都叫vacationer

2，在那些有zoo的，而没有pure的城市的visitor中，只有当他们去了pure的时候才叫vacationer。

所以，可以看出，pure比zoo的vacationer 的组成因子要多。所以，就解释了题目中的差别。

哈哈，我的思维比较简单，不知道这样对不对，还希望高人指教

题目怎么翻译呢？还是不太明白。请指点。谢谢！

有一种解释是：文中的主语是VACATIONER，而不是一般VISITER。
如果青岛有“SEA WORLD”(IN THE FUTURE)，假期的时候，VACATIONER FROM OTHER CITIES很可能去VISIT IT。而北京，济南都有ZOO，人们平时就去了，不用等待VACATION时候才去。

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.

应该解释成：在美国，一半以上的度假者去pure aquariums，却只有少于1/4的度假者去了有较小aquarium的zoo。主语为度假者，平时周日在本地zoo的就不叫度假者了。

(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.
因为zoos的数量太多，而pure aquariums的数量很少，所以即使相同的一批游客，他们占前者的比重，要小于占后者的比重
(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.
这是所有的visitors的情况，不能说明vacationers的情况。而且如果是这样的话，那么vacationers占据两者（pure aquariums的all visitors；zoo的all visitors）的比例可能相同，而不是不同（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.

又有新的理解！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.
因为zoos的数量太多，而pure aquariums的数量很少，所以即使相同的一批游客，他们占前者的比重，要小于占后者的比重。相当于把一部分钱都入到一个资金量很小的制造业，与投入到资金量很大的房地产业，其占后者的比重自然更小！
(C) Over the last ten years, newly constructed pure aquariums have outnumbered newly established zoos by a factor of two to one.
新建的数量不能代表总量是多少
(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.
这是无效的比较。文中比较的是度假者去zoo和去aquarium占总人数的比例。这里比较的是去zoo和不去zoo的参观者，“不去zoo”不能说明去aquarium，并且，该选项也只讨论了去不去的概率，但是不能说明vactioners在总人数中所占的比重。（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.
