853. There has been a 30- to 40-fold increase in the incidence of malaria caused by increasing mosquito resistance against pesticides.

(A) increase in the incidence of malaria caused by increasing mosquito resistance against
(B) increase in the incidence of malaria because of increasing resistance of mosquitoes to ANSWER
(C) increasing malaria incidence because of increasing resistance of mosquitoes to
(D) incidence of malaria increase caused by increasing mosquito resistance against
(E) incidence of malaria increase because of increased mosquito resistance to

A quick way to eliminate is based on the idiom 'resistance to.'

That leaves us with (B), (C), and (E). (E) is redundant, 'increase...increase'. You have a 30 - to 40-fold 'increase in' not 'increasing' so we can get rid of (C). That leaves us with (B).

Malaria cannot be caused by resistance of mosquito. However resistance of mosquito can be one of the reason why incidence of malaria is increasing. Hence B

C, D, E are awkward.

Between A and B, IMO the answer is B.

Reason:
A: "resistance against pesticides" is ambiguous, and hurts the meaning of the sentence.
B: "resistance ...to pesticides" is more clear.

OA please.

Thanks,

There has been a 30- to 40-fold increase in the incidence of malaria caused by increasing mosquito resistance against pesticides.

(A) increase in the incidence of malaria caused by increasing mosquito resistance against
(B) increase in the incidence of malaria because of increasing resistance of mosquitoes to
(C) increasing malaria incidence because of increasing resistance of mosquitoes to
(D) incidence of malaria increase caused by increasing mosquito resistance against
(E) incidence of malaria increase because of increased mosquito resistance to
Show more

Official Explanation:


Choice A can be faulted because it is not at first clear whether caused by modifies increase or malaria. Also, the proper expression here and in choice D is not resistance against but resistance to. Choices C, D, and E are wrong because the completed sentence must read 30- to 4O-fold increase.In these choices, 30- to 4}-fold illogically modifies incidence; furthermore, incidence of . . . increase in D and E is illogical. Choice B is best.

1. In B what you have is not the subordinate conjunction 'because' but the prepositional phrase 'because of '. Hence, there is no need for a clause after 'because of'.
2. All the same, I feel ' because of' is not appropriate here. If you want to use 'because of' then, you should reword the sentence as
- The incidence of Malaria has increased 30 to 40 fold because of … Perse, I feel 'due to' should have been used in the context.

Probably in 1988, some three decades ago, GMAT was not very fastidious about 'due to' or 'because of' .

(A) increase in the incidence of malaria caused by increasing mosquito resistance against- Resistance against is an error.
(B) increase in the incidence of malaria because of increasing resistance of mosquitoes to- Parallel construction. Seems okay. Let's keep it.
(C) increasing malaria incidence because of increasing resistance of mosquitoes to- Increasing is incorrect verb
(D) incidence of malaria increase caused by increasing mosquito resistance against- Same as A.
(E) incidence of malaria increase because of increased mosquito resistance to- malaria increase in not parallel to increased mosquito

So, I think B. :)

I thought 'because' can not be used to provide reasoning support for nouns. Shouldn't we use 'due to' here?
