What inference can be made about Tierra from this passage?

reasoning from several particular examples to establish a general principle

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.  

hm, switch the relative; nominative and indefinite; objective ? not too bright in the knowledge of the english.
