What is a question tag

I think it is when you ask a question and it gets answered.

Explanation:

the answer is c: at the city park,it has two basketball courts, a playground, and a walking path.

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.
