Sorry for the wrong header for the topic. It is SC question.
The question id from businessweek.com website.
I also chose B as my answer. But the official answer is C.
Here are my thoughts about B and C:
Choice B: With choice B, the sentence becomes as follows:
The pesticide Azocide has proven ineffective
because of the chemical compositions of the pesticides already in wide use neutralizing its desired effect.
More simplyfying version: Something has proven ineffective because of some other thing neutralizing its desired effect.
Choice C : With choice C the sentence becoms as follows:
The pesticide Azocide has proven ineffective
due to other pesticides already in wide use, whose chemical compositions have been neutralizing its desired effect.
Simplified version: Something has proven ineffective due to some other thing, whose chemical composition have been neutralizing its desired effect.
My questions:
(1) Can the word "whose" be used for "
things"? The only reason I choice B over C was the use of "
whose" in C.
(2) After looking at the simplified versions above, which one do you find more compelling?
