### HideShow timer Statistics

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.
(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.

A bit tricky but here goes my explanation:

It's a numbers based question - so let's say there are 50 visitors to pure aquariums and 50 visitors to zoo aquariums. The argument says that around 30 visitors to pure aquariums are vacationers where as around 10 visitors to zoo aquariums are vacationers. How to explain this discrepancy ?

(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.
Argument is about vacationers/tourists - not locals : Rule out
(B) Virtually all large metropolitan areas have zoos, whereas only a few large metropolitan areas have pure aquariums.
Visiting metropolitan/urban areas is not mentioned in the argument - OOS
(C) Over the last ten years, newly constructed pure aquariums have outnumbered newly established zoos by a factor of two to one.
So this essentially means there are more pure aquariums than zoo aquariums. Doesn't help to understand why more tourists are going to PA's as opposed to ZA's.
(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.
Compelling evidence : If a visitor visits a ZA and is prompted to go to a PA - he adds to the existing traffic of tourists to PA. So this contributes to more tourist traffic to PA, explaining the paradox.
(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.
OOS - the size of aquariums is irrelevant.

There are few aquariums so this explains why there are more visitors from other cities.

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:
---------------------
(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. ---> This option mentions only local residents. So, discard it.

(B) 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.

(C) 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.

(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. ---> It only mentions likelihood (having a high probability) but not certainty. So, we can discard it.

(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. ---> 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.

Technext

very good question and i have to read the question and choices twice
My pic is B - if only few metros will have pure aquariums then visitors who are coming would like to see those rather than seeing zoo that is also present in there area as well

got it at last why D is wrong. Nice one thats why need to put this analysis for all:
(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.
We are talking about visitors or vacationers but still if it is true it weaks the argument

(B) Virtually all large metropolitan areas have zoos, whereas only a few large metropolitan areas have pure aquariums.
A plausible reason why vacationers would be more interested in visiting a pure aquarium than a zoo

(C) Over the last ten years, newly constructed pure aquariums have outnumbered newly established zoos by a factor of two to one.
Proportion of aquariums to zoos is not an issue

(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.
Probability of visit is not an issue

(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.
Size of zoo is not an issue

I missed this one but ans B seems obvious..

if more zoos are present at more places then the proportion of local people visiting the zoo is higher than vacationers.

POE works best in this problem.
Even though I didn't understand the full implication of choice B in the first go, I was able to figure out that other options just don't apply to the context.

pple mention POE...how does this work? Method of Elimination...
w/o a particular rule how can one eliminate?

The best way I could attack this problem was trying to be in the area of the premise/facts.
A simple answer such as "B" attacks it.
