A frequent subject of a literary work is good vs.

A frequent subject of a literary work is good vs evil.

Explanation:

Good and evil and their contradictions, confrontations and the implications that these concepts bring about people are a recurring theme in literature, in all its genres and styles.

For example, in fiction literature such as The Strange Case of Dr Jekill and Mr Hyde, where the character suffers a dual personality condition, with a normal existence and an evil and cynical hidden personality; or in the classic detective novels, with a good cop who wants justice, and an unscrupulous and bloody criminal.

Throughout the history of literature, this theme has been recurring. This is so because it implies human nature itself, where the duality of personalities and the implications of people's own actions necessarily imply a positive and negative assessment of events and situations.

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.  

the answer should be the first one. "many people find his lyrics very moving."

it by far makes the most grammatical sense and is very objective, removing any first person from the original sentence and keeping with the sentence fluency.
