IMO A through POE

If the sentence "so voracious are they as to become an economical" is used in any other sentence, would it be correct? If yes, then please give an example.

A wins. Standard idiom usage:"....so [adjective] that..."

Cheers.

2 -3 breakdown between economic and economical
economic is right here eliminating B,C and E, Between A & D, A is correct because D is awkward.

Hi all,

A for me too, though I had some doubts on whether `they` modifier was ambiguous as it could refer to wastes as well. The quick elimination criterion was economic vs economical where the former won.

D just seems very awkward.

This is a classic example in which knowing an idiom can make a question relatively easy. Not knowing the proper idiom, on the other hand, well the question becomes a little more difficult. With this question we at least have a little more to go on. First off, 'economical' vs. 'economic'; to be 'economical' is to frugal. Clearly caterpillars who spend their money wisely is not what the sentence is trying to convey. Out with (B), (C), and (E). (D) is a classic comma splice, leaving us with (A).

(B) they are of such voracity, they have become an economical
Missing "that". It is required to link the two clauses.

(C) so voracious are they as to become an economical
(D) such is their voracity, they become an economic
(E) there is so much voracity that it has become an economical
Awkwardly phrased.

(A) they are so voracious that they have become an economic
Conveys the point succinctly.

Though caterpillars transform large amounts of plant matter into animal tissue and wastes, and therefore hold an important place in the food chain, they are so voracious that they have become an economic threat to farmers whose crops they eat.

(A) they are so voracious that they have become an economic
(B) they are of such voracity, they have become an economical
(C) so voracious are they as to become an economical
(D) such is their voracity, they become an economic
(E) there is so much voracity that it has become an economical

Breaking it down:
economical - is incorrect word - that means frugal, hence B, C and E can be removed.
such is used incorrectly here, it is used to show examples, which is incorrect usage here. Remove D

Remaining A.

Though caterpillars transform large amounts of plant matter into animal tissue and wastes, and therefore hold an important place in the food chain, they are so voracious that they have become an economic threat to farmers whose crops they eat.

1) The sentence starts with a contrast word 'though'. Look out for contrast in the way sentence is constructed.
2) 'that' here is used as a connector.

3) Though caterpillars.................is a dependent clause and they are so...................is an independent clause. When dependent clause precedes independent clause, comma is used to connect the two clauses.
4) The use of present perfect tense 'have become' is correct because they are still a problem.

(A) they are so voracious that they have become an economic
(B) they are of such voracity, they have become an economical
(C) so voracious are they as to become an economical
(D) such is their voracity, they become an economic
(E) there is so much voracity that it has become an economical

Thanks?
