(D) by not only the foods that are eaten by patients but also by the times the foods are

E may be is the most concise and gramatically correct choices, but I don't like 'it'. Anyway, between A and E I choose... E

while I agree that my pick is E as well, I dont agree that foods are not countable. Food is not countable, foods are.

it can be used with out a clear referent.

Given that people eat food(s), food(s) is a redundant word in all answer choices.

E is my pick for brevity and correct usage of NO BA

Ok, I'm holding the MGMAT SC guide right now, and I flipped to the pronoun chapter and there is no mention of "it" not requiring an antecedent. I'm not saying you're wrong, but do you have some sort of proof to back this up? Because without proof, I'm going to assume that "it" follows the rules that every other pronoun abides by - namely, it must have a clear and unambiguous antecedent, agree with the antecedent in number, and be in the correct case. Following these 3 criteria, "it" in choice ( E ) is wrong because the pronoun lacks an antecedent, and therefore also does not agree with its antecedent in number.

Again, I'm not saying you're wrong, I'm just saying I've never heard of that and would like to see proof w/ examples.

I choose choice ( A ) because it has proper pronoun reference, follows proper use of the "not only...but also" construction, and is in the active voice.

hi guys,

Agree on the fact that food can be countable, my bad. If OA answer is E... well, just luck

Regarding the "it" in the answer E, I think it refers to "what patients eat"

Regards

in B by not only .... not only by makes the sentence as "by by when the patients eat them" when you separate both the sentences.

Jorge,

It is raining. what is it referring to?? nothing. the sentence is still correct. It has that privilege of not having a clear antecdent.

Read this explanation from a MGMAT instructor

i'd go with d. (the original post has 'x' as the official answer - is this a mistake?)
reasoning:
* 'it is by no means certain...' is better than 'there is no certainty...' for two reasons:
- first of all, it preserves the original meaning; remember that you have to preserve the original meaning, unless it's absurd. in particular, the original sentence says that 'it is by no means certain': in other words, it is not necessarily certain. choice d preserves the exact wording of the original on this point, so, a fortiori, it preserves the original meaning. choice c, however, is much more extreme than choice d: it states definitively that there is no certainty. you aren't allowed to change the meaning like that.
- also, 'there' is much more questionable than 'it'. here, the 'it' is an accepted english construction, not unlike the 'it' in sentences such as 'it is likely that he'll fail the exam' (a sentence that, hopefully, none of you would criticize). 'there', though, seems to imply some sort of place where we're looking for certainty and not finding it.

* 'expenditure of large sums of money' is clearer, and flows better, than 'expenditure of money in large sums'.
