Can someone please explain why C is better over B. I feel like vast "amounts" of time is incorrect. Kindly guide
Hello,
PavanGPrabhu. I would approach the question from a parallelism and meaning perspective. First, it is odd to pair a singular element—
a vast amount of time—with a plural one—
powerful supercomputers, as we see in answer choice (C). In fact, answer choices (A) and (E) repeat such a singular-plural pairing in some way. The writing would be cleaner with matched elements. Then, from a meaning perspective,
a vast timespan is one that can be defined, but how long would we care to make it? Ten thousand years? A million? An aeon? The point is, there are many interpretations of just what
vast can mean in such a context. Meanwhile,
vast amounts of time encompasses all such interpretations, and since
vast amounts and
powerful supercomputers are both plural, answer choice (B) is the safer bet.
This is a tough question, and I would not think twice about the iteration of the sentence with answer choice (C) inserted outside of a GMAT™ SC context. Good luck with your studies.
