Flies do not agree with that. Comparing species with flies.

C --out WHICH incorrectly refers to courtship.


E is my answer

I think GmatPrep sucessful because it can lure you into the trap. To illustrate, many of us, including me, fell in the D trap!

Thanks x2suresh, OA is E!

It seems to be conveying that purpose of assistance is "to taste the hydrocarbons", which is definitely not the intended meaning.

Hydrocarbons, with which fruit flies perfume themselves in species-specific blends, are known to be important in courtship, and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of others.


Quote:
(A) and apparently this assists flies that taste the hydrocarbons on prospective mates to distinguish their own species from that of
(B) and apparently this assists flies when they taste the hydrocarbons on prospective mates in distinguishing their own species from those of

'This' is used as an adjective, as per the GMAT. So what's 'this' referring to here, 'assists'? It cannot as that is a verb. Both of these are OUT!


Quote:
(C) which apparently assists flies that taste the hydrocarbons on prospective mates in being able to distinguish their own species from

Courtship assists flies? No. It's actually the presence of hydrocarbons. Plus that 'being able to' can be avoided. This is OUT!


Quote:
(D) apparently assisting flies to taste the hydrocarbons on prospective mates to distinguish their own species from those of

Hydrocarbons assist flies to taste hydrocarbons to identify the mate? This distorts the entire meaning as it states intent on part of the flies. Plus 'those of' is not required. This is OUT!


Quote:
(E) apparently assisting flies that taste the hydrocarbons on prospective mates in distinguishing their own species from

This is the right answer.
