Strawberries

by gmat_perfect » Sun Jul 18, 2010 11:11 am
Strawberries, unlike picking bananas that are green and can be ripened artificially, must be picked when they are fully ripe, and they remain at peak flavor for only four or five days after that.

(A) Strawberries, unlike picking bananas that are green and can be ripened artificially, must be picked
(B) Picking strawberries, unlike picking green bananas that can be ripened artificially, must be done
(C) Unlike bananas, which can be picked green and ripened artificially, strawberries must be picked
(D) Unlike with green bananas, which can be picked and ripened artificially, strawberry picking must be done
(E) Unlike picking bananas, strawberries cannot be picked green and ripened artificially, but must be picked

Why is B wrong?

Thanks.

B uses "picking strawberries" as a subject, which is a questionable construction; if you're using the gerund as a noun, it should probably say "the picking of strawberries." I also doubt the use of "that" in "that can be ripened..." since it seems too restrictive. You would probably want to use the comma + which construction there to indicate that it's green bananas in general being described, not a specific kind of green banana.
B is also just really wordy and awkward. Basically, the grammar issues in B are pretty obscure, but even if the grammar seems fine to you (and it's a tough call whether such minor issues would really be considered incorrect on the GMAT), when compared to choice C, it's definitely the less concise and clear of the two options. C has a simple noun as the subject, makes the modification easy to understand, and places "strawberries" near the pronouns referring to it.
Choices A, D, and E all have comparisons that aren't parallel, and can be ruled out for that reason.
