Hello,
Can you please assist with this:
According to findings derived from functional magnetic resonance imaging (MRI), the area of the brain in which a second or third language is stored depends on the age of the language learner; whereas each language occupies a distinct area of the brain in an adult learner, language areas overlap in a young child.
A. whereas each language occupies a distinct area of the brain in an adult learner,
B. whereas for adults each language occupies a distinct area of the brain and
C. each language occupies a distinct area of the brain when they are learned by an adult, while
D. each language in adults occupied a distinct area of the brain, while
E. each language occupying a distinct area of the brain for an adult learner, and
Thanks a lot for your help.
Best Regards,
Sri
mikemcgarry, what's wrong with D ?
I was stuck between A and D. Please help
Dear 2013gmat,
That's a great question, and I am happy to help.

This is a high quality question, as the official questions always are. Choice
(A) is definitely the best. What's wrong with
(D)?
The problems with
(D) are subtle.
1) Choice
(A) says "
in the brain of an adult learner" --- very precise, very sophisticated. The brain is definitely physically inside the learner. Choice
(D) says "
each language in adults" --- in exactly what sense is a language "in" somebody? This is metaphorical, a bit casual, a bit sloppy. This would totally pass as correct in colloquial English, but it's not quite as sophisticated.
2) We need a strong contrast construction after the semicolon. In
(A), the word "
whereas" is a strong contrast word, and it highlights the contrast as the focus. In
(D), the word "
while" is not as strong as a contrast word, and it gives the impressive that the first part is really the focus, and the second part is a contrasting afterthought.
3) The tense of the verb in
(D) is wrong --- it's past, but the tense after the underlined part is present.
All of these make
(D) less than ideal, so it is not nearly as good as
(A).
Does all this make sense?
