<p>I bought the services from Collegeboard, and these are questions i got wrong and didn't really understand why.
Thank you.</p>

<li>New Zealand A(had fostered) a thriving local music scene B(for decades), but it was not until the late 1980s C(when) New Zealand musicians began D(to reach) international audiences. E(no error).</li>
</ol>
<p>Answer is C but I'm not sure why. I chose A because i thought it would sound better with "fostered" not "had fostered." By the way, when do you use the word "had fostered" instead of "fostered," or "had been" or "have had been". Thanks.</p>
<ol>
<li>The A(figures cited) in the report do not B(collaborate) the author's claim that small hospitals C(generally provide) better patient care D(than do) large ones. E(no error)</li>
</ol>
<p>Answer says that its B, but I don't really get why. I chose D because i thought it should be "than those of". How do we know we can use "than do"?</p>
<p>Eagles, you’re right about the first correction being “that”, but I don’t believe your second correction is correct. Shouldn’t it be “corroborate”?</p>
<p>Also, as an explanation, JohnLee, I’m not sure how to explain the first sentence. The phrase “Had fostered” is correct because it introduces the conflicting second part of the sentence, beginning with “but”. Think of this sentence as being produced by the formula “This had been happening, but it wasn’t until THIS that it really started happening.” Also, the word in the place of “that” (“when” in the original sentence) is not indicating a point in time, which is done by “until”, but a turn of events. That’s the best I’ve got.</p>
<p>“Than do” is correct in the second sentence because “do” has been relocated from the end of the sentence, which could also be written “than large ones do”. This is correct for any verb that acts as a syntactic marker for another, as “do” does for “provide”.</p>
<p>Q.1
[Teeming with] hundreds of species of tropical fish, the [clear] waters of Caribbean Sea [provide] a paradise [for] scuba divers. [No error]
-‘Hundreds of species’ is compared with clear waters. Why isn’t this an illogical comparison? By the way, the answer is E, No error.</p>
<p>Q.2
My grandfather never learned to use a calculator, [as he
shops] he can accurately compute his grocery bill in his
head to within a dollar.
(A) but as he shops
(B) therefore, when shopping</p>
<p>Q.3
Except in mathematics, absolute proof is more often an
ideal to be sought than a goal to be reached, [a fact that
the courts recognize by setting] varying standards of
proof for different kinds of cases.
(B) which the courts recognize and set
(C) and this is recognized when the courts are setting
(D) and it is recognized by the courts when they set</p>
<ol>
<li><p>What comparison? There is no comparison in that sentence.</p></li>
<li><p>(B) makes a run-on sentence, and the “therefore” isn’t entirely logical anyway.</p></li>
<li><p>None of the answer choices you listed are correct. None of the pronouns (“which,” “this,” “it”) have clear referents.</p></li>
