IMO E.


can any of you tell what is the error in option D. how to make it a sensible statement?


In option D, the subject is 'the secrets of.....' but scientists are actually studying the behavior of fruit fly. So we can't use 'By studying' and 'the secrets of..' (as subject) both at the same time.

IMO E.. clear n concise.
study / studying of fruit fly shd modify scientists becoz scientists did that study. So, A,D are out..B is wrongly connecting 2nd independent clause by comma and also awkward. C removed verb "has" before enabled..

hence A and out.
'comparing... and' usage is wrong.
between C and E, 'on comparison of' sounds more idiomatically perfect than 'on comparing' (can anyone explain the grammatical rule here). so, E out.


neatly done..

OA is option C

neatly done.. :clap:

Among the options:

B, D, and E are by virtue of first word in the sentences, create a sense of contrast, but the verb "agree" does not go with them.

Option "C" is a restatement.

"However much" is a correct phrase....

Please provide the OA.

Guys my mistake.....it should be "A"

C,D,E are changing meaning.. I feel A is better/concise than B but can't fine any errors in b. So, IMO = A
Nipunbans Says

Instantly eliminate D and E as they both have used incorrect idiom - "agree for" and "agree".
Among A, B and C
C seems to be passive, hence abandoned.
Now between A and B
In B - "Despite of the fact .........may agree" kills the actual contrast in the sentence. It is actually changing the original meaning of the sentence.
A seems to be correct "However much" is a correct idiom.

What is OA ??

OA is A.

OE from Kaplan 800 :
"The options for this sentence present you with a list of different idioms from which to choose. Start with the end: is agree that, agree for, or agree correct? The first is fine, the second is unidiomatic because for doesn't go with agree, and the third is out because that is necessary in order for the sentence to make sense. That leaves (A), (B), and (C). (A) isn't particularly eloquent, but it's not grammatically flawed. (B) is out because Despite the fact doesn't fit with may agree (it can be a fact that they agree, but if we don't know whether they agree, then there's no fact to discuss). (C) is wordy, passive (more on this later), and it doesn't agree with the rest of the sentence; if you're skeptical, try reading it in. Only (A) survives."
