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? Explanation:
) 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. ---> This option mentions only local
residents. So, discard it.
) Virtually all large metropolitan areas have zoos, whereas only a few large metropolitan areas have pure aquariums. ---> Well, I could easily figure out this option as the answer by method of elimination but to provide reasoning as to why this should be correct, I referred Oxford Advanced Learner’s Dictionary
(The dictionary you can trust - 30 million copies sold
), which states a vacationer as a holidaymaker (a person who is visiting a place on holiday/vacation)
. So, this option makes sense. If few large metropolitan areas have pure aquariums, then people from other places will have to visit these areas that have pure aquariums.
) Over the last ten years, newly constructed pure aquariums have outnumbered newly established zoos by a factor of two to one. ---> Inconclusive because we don’t have any idea about the number
of zoos and aquariums that were present 10 years back
) 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. ---> It only mentions likelihood
(having a high probability) but not certainty
. So, we can discard it.
) 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. ---> It’s comparing irrelevant information (zoo aquariums of zoos & aquariums of zoos that have no pure aquarium nearby).
My choice is option B
Hope that helps.
I didnt understand why are you comparing Pureaquarium of one area to rest when question stem is providing the overall stats for the country (In the United States) . D is not the best answer but it is surely better than other options.
