<p>Hello, CC
I was wondering if any of you guys could explain some of the questions that I have trouble understanding.
1) No one but a fool would readily lend money to a person who is known (to be) a frequent gambler.
Wouldn't (to be) be changed to "as"?
2) It was obvious that all of the candidates had planned carefully for the televised debate, for each answer to the opening question showed evidence (of having been rehearsed). (Correct answer is E. No Error)
I chose D as incorrect because it just sounds awkward. Shouldn't it be "of being rehearsed"
3) I got this correct but I don't really understand it.
For any mayor of a vast metropolitan area, an understanding of current issues in all districts is not only (desirous) but also vital. Is it because desirous( I think is an adjective) and so desirous should be changed to "desirable"?
4) The Bus would not have had to take the long detour instead of the main highway if the bridge (did not become) treacherous in the aftermath of an ice storm.
I kind of have an idea of why this is incorrect. "in the aftermath of an ice storm" refers to after the ice storm but I'm not sure what "did not become" should be changed to.</p>

<li><p>Both “known to be” and “known as” are valid constructions. I think “known as” is more often used for titles though, so in this case, “known to be” would be the better choice.</p></li>
<li><p>“Having been rehearsed” is correct, because it is used to show that the candidates had rehearsed it in the PAST, before the debate. The form that you suggested could also be correct (i.e. rehearsed is used as an adjective).</p></li>
<li><p>“Desirous” means something different from “desirable”. “Desirous” is basically wanting of something, while “desirable” is being wanted (e.g. “She was desirous to know” vs. Knowledge is desirable")</p></li>
<li><p>You’re correct; the tense is incorrect. “Had not become” would have been a correct option.</p></li>
