<p>I do not understand the structures of these questions.</p>
<p>(A)[For most of] recent history, people have used energy wastefully, but (B)[now that] supplies of essential fuels are becoming (C)[rapidly depleted], environmentalists are urging people to change (D)[it]. (E)[No error]</p>
<p>A-- eliminated
B-- WHAT supplies? confusing; "that" is used arbitrary.
C--adjective is in correct form; and verb too because of "have used". C eliminated
D-- CHANGE WHAT? confusing
E-obviously this sentence is not grammatically correct. E eliminated.</p>
<p>At a time (A)[when] interest in twentieth-century classical music (B)[seems] on the verge (C)[to disappear], the avantgarde compositions of the 1960s and 1970s (D)[manage] to retain their popularity.</p>
<p>I picked up choice B because of wrong verb form. We cannot use In 20th century and [present simple]. However my answer was wrong.</p>
<hr>
<p>To insist that a poem means whatever one wants it to mean is often [ignoring] the intention and even words of the poet.</p>
<p>Why error is in [ignoring]?</p>
<hr>
<p>Thanks.</p>
<p>the first one is “D” because its ambiguous pronoun usage…</p>
<p>I think the second one is “C” since the infinitive doesn’t really work.</p>
<p>and the last one is a parallelism mistake where “ignoring” should be “to ignore” so that it is parallel with “to insist”</p>
<p>@grebob
you are definitely correct. Can you give me more explanations? Thanks.</p>
<p>Well for number one, “it” has no clear antecedent thus it should be changed to “environmentalists are urging people to change their wasteful habit” or at least something along these lines…</p>
<p>for number two you should really just try to take out all the prepositional phrases and just focus on the core meaning… so that when you read it it should go something like this : </p>
<p>At a time (A)[when] interest (B)[seems] on the verge (C)[to disappear], the compositions (D)[manage] to retain their popularity.</p>
<p>“A” is correct since “when” is used to refer to time…
“B” is also correct because “interest seems” is correct subject-verb agreement.
“C” is incorrect and should be changed to “of disappearing”
“D” is correct because “compositions manage” has correct subject-verb agreement.</p>
<p>Thank you so much.</p>
<p>@Suleyman95:
1,D is correct . “it” is ambiguous and it refers to nothing.
2, on the verge OF disappearing
3, it should be “to ignore” in order to be parallel to “to insist”</p>

Thanks. I understand it now.</p>
