improving sentences

<ol>
<li>Explaining modern art is impossible, partly because of
its complexity but largely because of it rapidly
changing.
(A) of it rapidly changing
(B) it makes rapid changes
(C) of the rapidity with which it changes
(D) changing it is rapid
(E) it changes so rapid</li>
</ol>

<p>The answer is C; I thought it was A. Please explain, this question is tough.</p>

<p>This question too please</p>

<ol>
<li>For months the press had praised Thatcher’s handling
of the international crisis, and editorial views changed quickly when the domestic economy worsened.</li>
</ol>

<p>A - crisis,and
B - quickly
C - when
D - worsened</p>

<p>Please explain why the answer is A</p>

<p>EDIT: nevermind, I didn’t understand the sentence before.</p>

<p>11 is a parallelism issue. Complexity is a noun, so the second part needs to be a noun too. C is the only choice that does this with any sort of grammatical coherence. For A to be plausible, it would have to read, “its rapid changing.”</p>

<p>For the first question, parallelism and verb tense is important. So, im gona assume that you know the answer is either A or C. It can’t be A because it does not have the same tense as the previous part of the sentence “…its complexity”. Instead choice A says “…it rapidly changing” which is not parallel to “its complexity”. however, Choice C corrects that problem because it says “…the rapidity…” which is consistent to “its complexity” --its in the right tense.</p>

<p>For question 16, you need a conjunction to connect the two independent clauses of the sentence which is correctly done as the sentence is written by adding the word “and”</p>

<p>The second question is an identifying errors question…</p>

<p>The correct conjunction is but.</p>

<p>And is wrong.</p>

<p>Oh yea you’re right…The way he wrote it i though it was sentence error question…my bad…the conjunction is but…you’re right. srry</p>
