I think both compared to/compared with is right in GMAT, but X compared to/with Y. Here X and Y should show some sort of statistics, Right? Please shower some light. For the purposes of the GMAT, consider compared to and compared with interchangeable. While these phrases often refer to statistical differences, the inclusion of actual numbers is not required. An OA in GMATPrep: Minivans carry as many as seven passengers and, compared with most sport utility vehicles, cost less, get better gas mileage, allow passengers to get in and out more easily, and have a smoother ride. Here, no numbers are included in the portion in blue. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.

This meaning is nonsensical. Eliminate C. D and E: male emperor penguins huddle over the nests in groups, which thereby reduces Here, which reduces lacks a singular antecedent. Eliminate D and E. The correct answer is A. The pronoun "it" in answer choice A couldn't be considered ambiguous?

The correct answer is A. The pronoun "it" in answer choice A couldn't be considered ambiguous? Energy or Rate Tks! A: reducing the rate at which they burn energy so that it is 25 percent lower Since the penguins are REDUCING THE RATE, we know from context that it refers to the rate, conveying that THE RATE is lower. Regardless, an answer choice may be eliminated for pronoun ambiguity only if an alternate answer choice avoids the ambiguity and is free of errors. Here, B, C, D and E are all incorrect for the various reasons discussed above. Thus, the correct answer must be A. _________________ Mitch Hunt Private Tutor for the GMAT and GRE GMATGuruNY@gmail.com If you find one of my posts helpful, please take a moment to click on the "UPVOTE" icon.
