Writing Question help peeps!!

<p>1) Altough his fantasy trilogy, The Lord of the Rings, was far better known than his linguistic research on Anglo-saxon verse, Professor Tolkien refused to grant interviews about the novels he (had written or otherwise to promote) his nonacademic work.
A)no error
B)had written or otherwise promoting
C)wrote nor otherwise promoting
D)has written nor otherwise to have promoted
E)wrote or otherwise promoting
The answer is A, I simply dont get it.</p>

<p>2) Experts predict that global warming (will cause sea levels to raise and lead to flooding) from tidal surges
A)no error
b)obviously wrong
c) will result in raising sea levels and leading to floods
d) will be the cause of sea levels' rising and flooding
E) will raise sea levels and lead to flooding</p>

<p>The answer is E, it seems to be the best answer. But what is wrong with C AND D</p>

<p>9) The fierce competition for grades among premed students (is because of wanting to be accepted by a top medical school)
A) no error
B) is because a desire to be accepted by a top medical school
C) stems out of wanting to be accepted by a top medical school
D)stems from the desire to be accepted by a top medical school
E)wrong </p>

<p>Thanks in advance</p>

<p>1) If you were wondering about “had,” that is correct - you need to use the past perfect here to indicate that he first wrote the novel, then refused to give interviews. </p>

<p>2) Use the active voice. E is active; C and D is passive. </p>

<p>3) D - is that correct?</p>

<p>Oh my bad. I did not realize " to promote" is parallel to “to grant”. I chose B initially for some weird reasons.
And this is the answer explanation of D " the original sentence is both redundant and informal. By substituting stem from the desire for is because of wanting, you create a stronger an more effective sentence.</p>

<p>2) there are more reasons for C and D being wrong
C: ‘raise’ is a verb, so ‘will result in raising’ does not make sense.
D: This is unnecessarily verbose. ‘will be the cause of’ = ‘will cause’.</p>
