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.

Please give your reasoning

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.

cheers -

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

What is OA?

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.

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.

There is no other choice other than A that strengthens the expert's position.

Experts need more help here with choice E. Pet owners also do not wear mask and hence more risk. Thus increasing cases.
