As others have pointed out, the subject is plural - RAINFALL and TEMPERATURE. This means that we can't use the subject pronoun "it" in the original sentence, as it would refer to a plural subject. Nor could we have a singular verb HAS, as in B.
The other answer choices also contain IT, but in a different context. TO MAKE IT POSSIBLE is an idiomatic expression, and within idiomatic expressions, we can sometimes use vague pronouns that don't have a specific antecedent. Generally speaking, the GMAT doesn't like vague pronouns, unless they're in idiomatic expressions, such as It is raining, etc.
In E, there is a different pronoun problem: THEM. Who is the "them" raising the variety of crops? The rainfall and the temperature? The Japanese people? If it's the former, that doesn't make much sense. If the latter, we don't actually have that antecedent in the sentence, so THEM is incorrect.
When choosing between C and D, we're left with an idiom distinction: MAKE IT POSSIBLE TO DO or MAKE IT POSSIBLE FOR DOING. As with other idioms, there's no rule here. MAKE IT POSSIBLE TO DO is simply the preferred form.
Hi expert:
Could you please explain what is the difference between below sentence.
Japen's rainall and temperature have made it possible to raise a variety of crops.
Japen's rainall and temperature have made it possible for japanese to raise a variety of crops.
What is the agent of the action
to raise, or who/what raise, if we do not explicite for japanese here?
I ask this question is because I remember Ron's explain of same structure for a prep question
https://www.manhattangmat.com/forums/hea ... t3173.html
I quote the explain from Ron:
* "heavy commitment by an executive to a course of action" is awkward and difficult to read. (you may have to be a native speaker to pick up on this, though)
much more importantly:
* makes it likely to miss...
this doesn't work.
technically, this would mean that "it" - an unspecified entity - is likely to miss the signs.
if you use the "it is ADJ..." construction, and the verb has a specific subject, you MUST include that subject in the construction. it is likely that the executive will miss...
The take away I can get is we can not inplicate the agent for the TO DO, otherwise the reader will keep on asking: Hey! who miss signs of incipient trouble ?
Many thanks
