I am going over a practice SAT test, and I cannot figure out why one answer is better than another for a particular problem. You are supposed to mark the answer that best replaces the underline portion of the sentence.
11. With billions of tons yet to be mined, some argue that coal conservation measures are unneccessary.
(a) With billions of tons
(b) Because billions of tons of coal are
(c) Because of coal in billions of tons
(d) By considering that there are billions of tons
(e) Aware of the coal in billions of tons
I was able to eliminate A and D because it leaves the subject ambiguous. I am guessing that you are supposed to eliminate B and E because of the preposition 'in'?
Any suggestions or comments?
