OFFICIAL EXPLANATION
The ancient Sanskrit epic, the Mahabharata, developed through a long process of oral recitation; tradition names the poet Vyasa as author of the core section of 8,000 verses from which is evolved the 24,000 verse redaction of Vaisampayana and the 100,000 verse redaction of Ugrasrava Sauti.A. from which is evolved the 24,000 verse redaction of Vaisampayana and the 100,000 verse redaction of Ugrasrava Sauti
Incorrect.
This answer choice is grammatically incorrect. The singular verb is does not agree with the plural subject the 24,000 verse redaction of Vaisampayana and the 100,000 verse redaction of Ugrasrava Sauti.
What helps us identify this question as a Subject Verb Agreement question as well as identify the mistake is the following Stop Sign: plural subject built of singular nouns connected by and
In addition, this answer choices makes incorrect use of the Present Tense (is evolved) to describe an action that occurred in the Past. Since the sentence tells us the ancient epic developed in the past, its phases of evolution also occurred in the past.B. with the 24,000 verse redaction of Vaisampayana and the 100,000 verse redaction of Ugrasrava Sauti having evolved from it
Incorrect.
This answer choice is stylistically flawed. Changing [i]from which to
with creates an awkward and confusing sentence; it does not clearly express the relation between the later redactions and
the core section of the Mahbharata. As a result, it may be understood that Vyasa also wrote the later redactions (
the author of A with B and C ...).
In addition, the phrase
having evolved from it is wordy and redundant.[/i]
C. from which have evolved the 24,000 verse redaction of Vaisampayana and the 100,000 verse redaction of Ugrasrava Sauti
While this answer choice corrects the Subject Verb Agreement mistake in the original question, it is grammatically incorrect -- it uses the Present Perfect tense have evolved to describe an action that occurred in the past.
Since the sentence uses the Past tense to tell us that the ancient epic developed gradually, the same tense should logically be used to describe the later stages of the text's evolution.D. from which were evolved the 24,000 verse redaction of Vaisampayana and the 100,000 verse redaction of Ugrasrava Sauti
This answer choice corrects the Subject Verb Agreement mistake in the original question, by changing the singular verb is evolved to the plural verb were evolved. It also corrects the Tense mistake, by using the Past tense to describe an action that occurred in the past.E. evolved from which is Vaisampayana's 24,000 verse and Ugrasrava Sauti's 100,000 verse redactions
Incorrect.
This answer choice repeats the Subject Verb Agreement mistake in the original question. The singular verb is does not agree with the plural subject redactions.
In addition, this sentence is stylistically flawed. The use of the possessive form in Vaisampayana's 24,000 verse and Ugrasrava Sauti's 100,000 verse redactions creates a long, complex, and confusing modifying phrase -- an awkward way of describing the two parallel items.
