Relative modifiers

[gmatalongthewatchtower]

ManhattanGMAT Staff,

I went through Stacey's reply to one of the OG-12/126(SC) question. I understood the explanation but my curious mind raised another question.

I am not too concerned about the answer choices and which one wins over which, but I am more concerned about the grammatical concepts.

Here's the sentence that Stacey quoted:
The use of GMAT books is based on the assumption that studying produces hormones in an individual that create unconscious physical responses.

....that studying produces .... is a noun clause.

Let's drill down further

studying produces hormones in an individual that create unconscious physical responses.

How do I know whether "individual" modifies "unconscious physical responses" or hormones modify "unconscious physical responses" ?

Can you please help me ? All my previous posts are in the queue for more than two weeks now. I am relatively new to the forum and I am not sure about the average wait time. Sometimes it gets really frustrating because I lose track of the actual problem.

I hope my query will be answered.

Secondly, is there any grammar book that you would recommend? I believe in self-learning even if it requires me to dig through thousands of pages. Sometimes I feel that it's better to get an answer yourself rather than waiting for weeks together.

Thanks

thanks for your patience. some forums have longer wait times than others, but usually you will wait anywhere from a couple of hours to a couple of weeks for an answer. they all get answered eventually though..

to be honest, your best bet on grammar is our SC strategy guide and what our instructors say on the forums. any outside sources run a risk of not reflecting the GMAT's use of grammar (they use slightly different rules than what you will find elsewhere)..

anyway, the answer to your question lies in the word "create". hormones create, but an individual creates. since they used "create", we are obviously referring to hormones..
