OG 16 Medium level Cause and Effect question.

Post Fri Sep 18, 2015 4:00 am
One summer, floods covered low-lying garlic fields situated in a region with a large mosquito population. Since mosquitoes lay their eggs in standing water, flooded fields would normally attract mosquitoes, yet no mosquitoes were found in the fields. Diallyl sulfide, a major component of garlic, is known to repel several species of insects, including mosquitoes, so it is likely that diallyl sulfide from the garlic repelled the mosquitoes.

Which of the following, if true, most strengthens the argument?

(A) Diallyl sulfide is also found in onions but at concentrations lower than in garlic.

(B) The mosquito population of the region as a whole was significantly smaller during the year in which the flooding took place than it had been in previous years.

(C) By the end of the summer, most of the garlic plants in the flooded fields had been killed by waterborne fungi.

(D) Many insect species not repelled by diallyl sulfide were found in the flooded garlic fields throughout the summer.

(E) Mosquitoes are known to be susceptible to toxins in plants other than garlic, such as marigolds.

OA D. Could some one help me understand the Cause and Effect reasoning in this question and also help me understand why is the OA authentic as per the Cause and Effect rules. I am having a hard time applying the Cause and Effect concept!

I chose D,though I don't know it is right or not. because it eliminates the possibility that other insects not repelled by DS were also killed,thus strenthening the argument.
