providing them with high-energy feed, and milking them regularly, Holstein cows are producing
providing them with high-energy feed, and milked regularly, the Holstein cow produces
provided with high-energy feed, and milking them regularly, Holstein cows are producing
provided with high-energy feed, and milked regularly, the Holstein cow produces
provided with high-energy feed, and milked regularly, Holstein cows will produce
This is from an old paper-based GMAT and one of those tough ones in which nothing really sounds right.
So, A should say "providing them with high energy feed, and milking them regularly, Holstein cows are producing " This makes a list out of "to keep," "providing," and "milking" which is a list, but it fails the parallelism test. Also, the verb tense "are producing" is wrong - if the farmer takes care of them, they will respond a certain way. Eliminate A. (Note that I added a comma missing from the original text, above.)
B also has parallelism issues (providing, milked), as does C (provided and milking). D and E have parallelism with provided and milked, but they still don't match "to keep." And this is where this one gets really hard. Most people will want to keep this as a list of three things, with those three words properly parallel - and that would be a good way to write the sentence, but they haven't given us that option.
If we lopped off that opening clause, we'd have "Provided with high energy feed, and milked regularly, Holstein cows..." That's okay. Then they add this separate clause out front (the "For the farmer" bit) and this is what makes it sound bad b/c we want to combine that opening clause with the provided and milked piece. Since we don't have that as an option, we're forced to look at them as separate items (though we do still want parallelism between provided and milked).
Then, we're just left with "produces" vs. "will produce" since D and E both use provided and milked. The sentence begins "For the farmer who takes care to keep THEM cool" so we have to use plural for the cows. Answer D uses singular, so E is the answer.
