An example of a specific topic is .
a Birds of the World
b Mars
c Astronomy

mars

As the topic specifically deals with a planet while other topictalks about different aspects at the same time

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.  

there is no paragraph seven here.
