THEIR is causing ambiguity in D. Not sure if "their" refers to cars or manufacturers. C is correct. No pronoun antecedent issues.

adam15, D is also incorrect because "more" seems to modify fuel-efficient small cars indicating that the number of fuel-efficient small cars has increased, whereas in C, more correctly modifies fuel-efficient.

I think what threw me for a loop was "those". What is proper use of those? I know it's a demonstrative pronoun, as in "those cars, over there". Why can "those" not refer to manufacturers, just to play devil's advocate?

BTW: (D) and (E) are wrong because they change the meaning. (D) and (E) seem to imply manufacturers are able to make MORE (i.e. quantity) fuel-efficient cars, whereas A-C imply manufacturers are able to make cars MORE fuel-efficient.

Can someone explain why "that" is needed? Why is the original sentence wrong?

That introduces a restrictive clause...without that the sentence lacks coherence

meaning.. that clause is used to introduce useful information about small cars...

if you remove the that caluse.. the small cars is hanging up in air with no wheels..;-p

Today's technology allows manufacturers to make small cars (...) than those at any other time in history (you cant build a meaningful sentence without that clause)


For this: Please read.. THAT vs WHICH.. you will get a better picture..

Plz..correct me if i am wrong..
Thanks

"cars" must be compared to "those"

"any other time" is right. "any time " is wrong. we need "other" to exclude the time of today. remember "ANY OTHER " from now on

In D, "more" modify "cars" and so is wrong
