200. Certain pesticides can become ineffective if used
repeatedly in the same place: one reason is suggested by the finding that there are much larger populations
of pesticide-degrading microbes in soils with a relatively long history of pesticide use than in soils that are
free of such chemicals.


(A) Certain pesticides can become ineffective if used repeatedly in the same place; one reason is
suggested by the finding that there are much larger populations of pesticide-degrading microbes in
soils with a relatively long history of pesticide use than in soils that are free of such chemicals.

(B) If used repeatedly in the same place, one reason that certain pesticides can become ineffective is
suggested by the finding that there are much larger populations of pesticide-degrading microbes in
soils with a relatively long history of pesticide use than in soils that are free of such chemicals.

(C) If used repeatedly in the same place, one reason certain pesticides can become ineffective is
suggested by the finding that much larger populations of pesticide-degrading microbes are found in
soils with a relatively long history of pesticide use than those that are free of such chemicals.

(D) The finding that there are much larger populations of pesticide-degrading microbes in soils with a
relatively long history of pesticide use than in soils that are free of such chemicals is suggestive of one
reason, if used repeatedly in the same place, certain pesticides can become ineffective.

(E) The finding of much larger populations of pesticide-degrading microbes in soils with a relatively long
history of pesticide use than in those that are free of such chemicals suggests one reason certain
pesticides can become ineffective if used repeatedly in the same place.

I did get the answer A, but could not adhere to the time limit. In general, how do you approach such crazy questions
Whether you think you can or can't, you're right.

It is actually very simple. And one gets lost b'cos that is what GMAT preparers intend :)

B and C - If used repeatedly in the same place, one reason..blah ---misplaced modifiers.

D - the finding that...blah blah...is suggestive of one reason, if used --- incorrect sentence formation one reason must be followed by 'that'

E - blah...suggests one reason certain pesticides --- incorrect sentence formation

It is useful to read the sentence as it is and first find the mistakes in it. If we find a mistake then go ahead and find an option that corrects that mistake. If there is no mistake then go ahead and find an option which is better (voice, structure, etc)

Elimination method (finding at least one mistake in the sentence) always works better for SC.

wowwww...

With good knowledge of modifiers, one can eliminate B,C and D.
E is not good here because of "the finding of" and "those". "The finding that " and "in soil" would do the trick.
So, A wins.

It took me 2 minutes to read and understand the whole things....(which is worrisome)

i was confused between B and A
I could not comeup with sufficient reason to miss A ....so decided to go with A.....

(i missed the misplaced modifier in B earlier...)
