The final description of Jack is as follows: “… a little boy who wore the remains of an extraordinary black cap on his red hair and who carried the remains of a pair of spectacles at his waist”.

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.
