If a writer wished to introduce a narrator in a story, which sentence would work best for this purpose? a) the capital of georgia is atlanta. b) what is the best birthday present you were ever given? c) the discovery of the new world is an event of major importance. d) some people say that i'm overly cautious, but i just like to be prepared.

a) walter looks unhealthy

the sentence that avoid faulty coordination is:

culture, which is well represented in philadelphia, plays a major role including theatre, music, and the visual arts.  

faulty coordination occurs when the writer gives equal importance two different ideas (clauses) which in fact are not equivalent. in order to correct a misplaced clause or idea, the writer can place less important or emphatic ideas in a relative clause as in the previous sentence.
