In Choice C As + prepositional phrase does not work in the context of this sentence because the main clause contains an action that needs to be compared with another action after
as. This action is missing in Choice C.
Hi
nishatfarhat87,
This is not a correct analysis of Choice C, in my opinion. The Official GMAC answer explanation is also lacking, but I will do my best to explain it more clearly.
The main clause does not contain an action that needs to be compared with another action after "as", because the two-part comparison has already been made (Robert Johnson vs. other Mississippi Delta blues singers). Furthermore, it's not the
verbs that are being compared: it's the
nouns (R.J. versus other blues singers).
Rather, the GMAC does not want us to use "as with" when comparing two nouns or noun phrases, as it says in the official answer explanation, even though this is normal English usage. Instead it prefers the one-word term "like," which is more concise.
In everyday English, "As with other GMAT tutors, I am asked about this question frequently" is a perfectly valid sentence (although GMAC disagrees with me in its answer explanation). However, "Like other GMAT tutors, I am asked about this question frequently" would be even better.
There is a second part of this answer choice that is not technically incorrect, but displays somewhat poor usage. It's the part that says
"Robert Johnson made music that arose from an oral tradition beginning as a mixture of chants, fiddle tunes, and religious music and only gradually evolved into the blues."In the GMAC's official explanation, it incorrectly refers to "beginning" as the present participle, but that's not necessarily true. It's only the present participle if there is an actual present-tense helper verb in front of it, such as "am helping" or "are helping." However, it can be used in a variety of other tenses as well: "were helping" (past) or "had been helping (past perfect)," or "will be helping" (future). As you can see, the gerund (-ing) can be used to describe past, future, or present. Here are some additional examples:
Past: I opened every present, beginning with the largest one.
Future: Next year I will take better care of myself, starting with my diet.
So, why is "beginning" a poor choice? Because despite the fact that it's not incorrect, it does still imply the present tense in some ways, and thus sounds odd when preceding a past tense verb ("evolved"). This error can also be seen in Choice D. It's better to use the past tense in both instances, which is what we see in the correct answer choice, E.
Technically, the best way to precede a past tense verb is with a past perfect verb. For example, "I
had walked outside when it
began to rain" is slightly better than "I
walked outside when it
began to rain," because in the second version the order of events is less clear, which obscures meaning.
Thus, here is my perfect version of the sentence:
"Like the music of other Mississippi Delta blues singers, Robert Johnson's music arose from an oral tradition that had begun with a mixture of chants, fiddle tunes, and religious music and only gradually evolved into the blues."
