HideShow timer Statistics

People who have spent a lot of time in contact with animals often develop animal-induced allergies, some of them quite serious. In a survey of current employees in major zoos, about 30 percent had animal-induced allergies. Based on this sample, experts conclude that among members of the general population who have spent a similarly large amount of time in close contact with animals, the percentage with animal-induced allergies is not 30 percent but substantially more.

Which of the following, if true, provides the strongest grounds for the experts’ conclusion?

(A) A zoo employee who develops a serious animal-induced allergy is very likely to switch to some other occupation.

(B) A zoo employee is more likely than a person in the general population to keep one or more animal pets at home.

(C) The percentage of the general population whose level of exposure to animals matches that of a zoo employee is quite small.

(D) Exposure to domestic pets is, on the whole, less likely to cause animal induced allergy than exposure to many of the animals kept in zoos.

(E) Zoo employees seldom wear protective gear when they handle animals in their care.

A. A zoo employee who develops a serious animal-induced allergy is very
likely to switch to some other occupation. [Zoo employee job attrition is out of scope – eliminate it]
B. A zoo employee is more likely than a person in the general population
to keep one or more animal pets at home [Pets in home – out of scope- eliminate it]

C. The percentage of the general population whose level of exposure to
animals matches that of a zoo employee is quite small. [Hold it]

D. Exposure to domestic pets is, on the whole, less likely to cause animalinduced
allergy than exposure to many of the animals kept in zoos. [Types of animal induced allergy is not the intent of the argument – eliminate it]
E. Zoo employees seldom wear protective gear when they handle animals
in their care. [Protective Gear is not discussed in the argument – eliminate it]

, the percentage with animal-induced allergies is not 30 percent
but substantially more.

The key to this claim is that on the one hand, you have zoo employees and on the other, exposed members of the general population. (A) says that if allergic zoo employees (ie 100% allergic rate) switch to other jobs, then the percentage of exposed people (ie 30% allergic rate) who are allergic must be higher (ie a blended rate somewhere between 30% and 100%).

Thanks Paul and bsd_lover,

I got the point.

I attributed "People who have spent a lot of time in contact with animals often develop
animal-induced allergies, some of them quite serious" to zoo employees and directly took wrong thought track.

Thanks

I get A as well.

Conclusion:
"experts conclude that among members of the general
population who have spent a similarly large amount of time in close contact
with animals, the percentage with animal-induced allergies is not 30 percent
but substantially more."

In other words, a higher percentage of the general population will have animal-induced allergies. We need to strengthen this conclusion be selecting the answer that provide a reason why more people in the general population would have these animal-induced allergies.

A. This statement tell us that once people develop these allergies in the Zoo profession they switch to the general population. So the animal exposed general population should be at 30% plus the additional ex-Zoo workers which should make it higher. Correct

B. This is irrelevant because we are not concerned about the general population as a whole but instead only those in the general population who are exposed as much as Zoo workers. Even if it was relevant it would provide evidence that Zoo workers should have a higher rate of allergies and would weaken not strengthen.

C. This is irrelevant as well because were dealing with percentages.

D. As in B this would provide evidence that Zoo workers should be more exposed and weakens not strengthens.

E. This would also provide evidence to weaken and not strengthen.

A is the best, because if a zoo worker moves to some other occupation then the other workers in that occupation might be affected because of the zoo worker...

Here in E experts say "the % of people induced with allergies is more than 30%" that itself suggests that people might not have used any protective cover which suggests strongest conclusion of experts argument, if the people have used protective cover then the % of people induced with allergies might have decreased.

Hope this helps

+1 Kudos if you have liked the explanation

we can't assume that human beings i.e. zoo workers can transmit "animal-induced allergies"

A is the correct answer in my opinion and you are right, we can't assume that they transmit animal-induced allergies after changing jobs.
When a zoo worker leaves the zoo, he becomes part of the population that is referred to as "general public", basically anyone who is currently not working as a zoo worker. As over the years many such zoo workers would have switched jobs, the percent of general public with animal exposure and animal-induced allergies would have increased.

hope this makes sense.

I picked E, but A also seems to be a good candidate after a little thought

What is OA?

A
cant be E as
we need to prove that number of people having animal allergy is more then the sample collected
A ) proves that people who have got these allergies have already left there jobs

Yes I agree. A makes the most sense. The other choices are not quite likely. A can safely be inferred.

C. The percentage of the general population whose level of exposure to animals matches that of a zoo employee is quite small. this actually weaken the conclusion. If level of exposure is low so would be percentage of people having allergy
D. Exposure to domestic pets is, on the whole, less likely to cause animal induced allergy than exposure to many of the animals kept in zoos. weakens the conclusion
E. Zoo employees seldom wear protective gear when they handle animals in their care. weaken the conclusion

A.

A. If they change professions then it is very possible that 30% reflects a lower number of people than were actually affected by animal induced allergies.
B. B weakens the conclusion so wrong
C. Weakens
D. Weakens
E. Does not strengthen.

Hence A

IMO A.

Reasoning is on the fact that the first choice ( eventhough not best fit IMO) is a better justification for the conclusion mentioned in the passage.
