The original sentence:
The use of GMAT books is based on the assumption that studying produces hormones in an individual that, in turn, create unconscious physical responses. (Yes, I know the meaning of the sentence is kind of amusing - I'm trying to match some singular and plural stuff in the original sentence!)
The "in turn" bit is just a little modifier tossed in to break up the sentence a bit and confuse you. Ignore it!
The use of GMAT books is based on the assumption that studying produces hormones in an individual that create unconscious physical responses.
Core:
The use <of X> is based on the assumption that studying produces <Y>.
Modifier Y:
hormones <in A> that create <Z> responses
No problems with core or modifier so far. I assume that the people who chose C thought there was something wrong with A, so let me know what you thought was wrong.
Now, adapting our new sentence for choice C:
The use of GMAT books is based on the assumption that studying produces hormones in an individual creating, in turn, unconscious physical responses.
Core:
The use <of X> is based on the assumption that studying produces <Y>.
Modifier Y:
hormones <in an individual creating responses?>
Still no problem in the core. That modifier, though... that's messy. There's no comma between "individual" and "creating" and that's a big problem. Try this phrase:
"stress in an individual studying hard for the GMAT"
What does that "studying hard for the GMAT" refer to? In this sentence, it's modifying the individual - and that makes sense.
But what about our example above? It's ambiguous here - "individual" is a candidate for the noun, because an individual can create unconscious responses... and so can the hormones... and, hey, so can studying! Which is it? Ambiguity = bad.
Note that there is no ambiguity in A, because the conjugated verb "create" can match only with a plural subject, so it must match with the plural "hormones." Now we know that it's definitely the hormones creating the responses.
Just to get more clarification.
The use of GMAT books is based on the assumption that studying produces hormones in an individual creating, in turn, unconscious physical responses.
In the above example, the word 'creating' modifies the nearest noun 'individual' , therefore it is incorrect . you already mentioned that.
Now, I am modifying the sentence a bit:
The use of GMAT books is based on the assumption that studying produces hormones in an individual, creating, in turn, unconscious physical responses.
I just added a comma after the word individual. Now it is a case of ', ing' modifier and should modify the whole clause 'studying produces hormones in an individual' . In this sentence , ', creating' can only modify 'studying' as it is the subject and not hormones. But the intended meaning is to modify 'hormones' , therefore it is wrong.
Pl. let me know whether I am correct in my analysis.
