<li><p>Introducing new ideas and replacing old ones is always a highly controversial matter, especially when there is already tension between an older and a younger generation.
A. Introducing
B. old ones
C. is
D. especially when

B. make it difficult to
C. is
D. more likely
Answer: E (im confused about the whole ‘it’ thing so i wrote down B. does it not need an antecedent?)</p></li>
</ol>

<p>For 14, "introducing new ideas and replacing old ones" is a single process. The hint that they wanted singular was that they called it a "matter" and that was not an option for correction, so the subject had to be a single matter, meaning a singular verb.</p>

<p>23 is just a standard appositive, nothing grammatically incorrect about it.</p>

<p>For 29, the antecedent (despite its name) does not have to come before the pronoun, as long as it is named.</p>

Guys even I didn’t get the last question…(29th)
Can someone exlpain me why it is correct…?
Please help
Thanx in advance

When “it” is a dummy pronoun (or “expletive pronoun”) it doesn’t require any antecedent, as in phrases like “it is raining” or “it is unfortunate that you are not a potato,” “The mountainous terrain makes it difficult to build a cluster of yurts in which to make a long-term bivouac.” @abcdefgh3

It makes complete sense…thank you so much marvin100…
Please can you give me some suggestions for the essay writing…? I have my SAT in November…
Thanx in advance
