Today's technology allows manufacturers to make small cars more fuel-efficient now than at any time in their production history.
A) small cars are more fuel-efficient now than at any time in their
B) small cars that are more fuel-efficient than they were at any time in their
C) small cars that are more fuel-efficient than those at any other time in
D) more fuel-efficient small cars than those at any other time in their
E) more fuel-efficient small cars now than at any time inA) The "are" is unnecessary, and "at any time" should read "at any
other time." Otherwise it is an invalid comparison, since
now is also a time. That's like saying "Sachin Tendulkar is better than any cricketer," which of course should read, "Sachin Tendulkar is better than any
other cricketer," because he is not better than himself!
B) Again, "at any time" should read "at any
other time."
C) Correct. "those" is an elegant way of referencing "small cars," and it also preserves the focus and meaning of the original.
D) We cannot compare a verb to a noun. In other words, we cannot compare how many cars are
made to the
cars themselves.
E) Sounds pretty good other than the "at any time" vs. "at any
other time" issue that we should already be aware of, thanks to answers A/B vs. answers C/D. You could also argue that it shifts the meaning slightly from the original, changing the focus from
small cars that are fuel efficient to
fuel-efficient cars that are small.
You could also argue that both the answer choices with the word "now" (A and E) are redundant because of the reference to "Today's technology."
When confused by a tough SC, don't forget to compare and contrast your answers for inspiration. Omitting the "other" from this expression is a common mistake, but you can catch this mistake by scanning vertically, and paying close attention to the small differences between each answer choice.
