I have this question, and I'd like to know the extrapolation for choosing the correct answer
Foods of animal origin generally supply greater amounts of iron to the diet than ----------
(A) are foods of plant origin,
(B) foods of plant origins
(C) do foods of plant origin
(D) plant origin foods
I'm confused between B and C and I can't quiet know why one of them is incorrect.
Thanks for your reply,
I also chose B, but it seems that the correct answer is C as the book suggests. your are correct that we have a comparative condition here. The only explanation that I came up with is that we have a logical/ illogical comparative condition here.Take for example that its not correct when we say " the climate in the north is hotter than the south", there is an illogical expression after " than" (... than the climate in the south). I think we have the same situation here. but I wanted to make sure that others will agree with me in the above.
thanks a lot again.
