Alright, I'll bite: how can I not provide an explanation for the "Cool Papa Bell" question?
Among baseball's all-time fastest baserunners, perhaps it is none that was faster than James "Cool Papa" Bell, who is reputed to have rounded the bases in only 12 seconds on many occasions.
A. perhaps it is none that was faster than
B. maybe none was faster than
C. there was maybe no one who was faster than
D. perhaps none was as faster than
E. there is maybe none who was faster than
Answer choice analysis:
CHOICE A: This would sound great if it were to read "perhaps none was faster than," which would be the perfect solution. Unfortunately, it doesn't: there's an extra "it is" and "that" thrown in there, which makes the sentence wordy / contradictory (using a present tense and a past tense verb to describe the same person). Eliminate.
CHOICE B: Correct. "Maybe" isn't quite as good as "perhaps," but they are virtually equivalent. "None" (not one) is a singular pronoun and is conjugated correctly ("he/she/it was").
CHOICE C: This would sound great if it were to read "there was maybe no one faster than," which would be a great fit, but again, AS IN CHOICE A WE ARE UNNECESSARILY DOUBLING UP ON THE VERB ("was" + "was"), which is clearly redundant. Eliminate.
CHOICE D: Although the word "as" is often used in comparisons ("There are few standardized exams AS hard AS the GMAT". etc.), it should not be used in combination with an -er comparison, like "as faster" or "as slower." Eliminate.
CHOICE E: Again, as in Choices A and C, we are using the verb "was" twice with the same subject. This just goes to show that WHEN YOU SEE A CERTAIN ERROR ON GMAT SC, THAT ERROR IS LIKELY TO REPEAT ITSELF IN OTHER ANSWER CHOICES.
My Perfect Version: Among baseball's all-time fastest baserunners, perhaps none was faster than James "Cool Papa" Bell, who is reputed to have rounded the bases in only 12 seconds on many occasions.-Brian
