In my english class we are working on a murder case that happened back in 1999 and its also a podcast called serial and i need to find out what sarah koenig who is the producer of the podcast what her opinions are about the murder case so if possible i need finding out what her opinions are.

it does not state in the pod cast exactly what her opinions are on the case

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.  

"it's more of an essay than story, but perhaps it is best described as a mood-piece: it uses a lot of musical imagery, not to mention sea imagery, religious imagery, and any other imagery that suits his purpose."
