When should a period appear within a citation?

If a citation in parentheses follows the quotation, the period follows the citation. If a superscript footnote number is used, it follows the period and the quotation marks. a) The Portland vase is “blue porcelain,” according to Compson (435). Comma is within the quotation marks; the period follows the citation.

hi,   i believe the outlines that were supposed to be showing at the sentences, are not. could you highlight them somehow?

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.
