Write a made-up or true story about an uncovered family mystery. Include the following in your story: Sundary, secret, wallpaper, swap, sister, curiosity, island, notebook, marathon, demand.

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.  

if you read the story there are characters like the neighbor, son, wife, and him himself.
