Read the sentence below and answer the following question:
"it was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness…" —charles dickens, a tale of two cities
what is the advantage of repeating the syntax of the initial clause “it was the…”?
the monotone creates a feeling of disaster.
the parallel words make the reader confused.
the pattern suggests that music will be used.
the repetition creates a comparison/contrast theme.

The answer to the question above would be that the advantage of repeating the syntax of the inital clause is that the repetition creates a comparison/contrast theme.

Charles Dickens has used the same structure to talk about opposites: he says that it was the best of times at the same it was the worst of times and adds that it was the age of wisdom together with the age of foolishness. He uses the same syntactic construction to refer to both positive and negative things and, in this way, creates a comparison/contrast theme.

from the political point of view it could be said that the candidate   is an effective speaker because she takes a strong position on the issue. it is an open discussion but probably she is making a presentation and can choose which subjects she wants to address. she is very likely to attain her aim which is to convince voters to accept her proposal.
