<p>Correct Answer: C
Why is A wrong and C right?</p>
<p>(In the opinion) of hte lecturer, (a background) in history of the Middle Ages is not a condition necessary (in) (the enjoyment of) medieval literature.</p>
<p>Correct Answer: C
Why is this idiomically incorrect?</p>
<p>A is incorrect because it is far too wordy, and the "or did not" doesn't even make sense. "Whether the ancient Egyptians sailed or not" is even too wordy, although passable. C fixes that problem. Plus, A is idiomatically incorrect (again, "or did not" isn't really common). Perhaps someone can come up with a more complete/"official" explanation.</p>
<p>For the second one, the correct word is "for," not "in." It's just an idiom. It's not necessary FOR something.</p>
<p>hm...
1 should be D.
C doesn't make sense. i'm sure i did this problem before, and i had no trouble with it,so i think its D. the whole "that...sailed"is a noun clause, it should be correct.
A is excessively word, u dont have to say "whether... or did not", simply "whether...." is sufficient. </p>
<p>2 i agree. necessary..for
necessity..of?
i think so xd</p>
