Say you have a pronoun in the independent clause after the semicolon. Can the pronoun refer to the noun in the independent clause before the semicolon?
Des the vice-versa also hold good?
Yes it is possible,
John stood first in Maths test; he also won the second prize in debating.
here 'he' the pronoun in the second refers to the noun 'John' in the first clause.
If you use the same vice-versa the above sentence would sound awkward
eg He stood first in the class; John also won the second debating prize. -- awkward
The above construction is awkward if used as a single sentence, but it could very well fit in a paragraph. But in GMAT we have only one sentence per question, so it would be an awkward and a less preferred sentence.
It is awkward but is it incorrect grammatically and will it be wrong on gmat?
