Which story is most likely an example of an allegory

Allegory, from the Greek ἀλληγορία (allegoría) "figuratively", is a literary figure or artistic theme, which aims to represent an idea using human forms, animals, and / or everyday objects.

The allegory aims to give an image to what has no image, so that it can be better understood by the generality. Drawing the abstract, making "visible" what is only conceptual, obeys a didactic intention. Thus, a blind woman with a scale is an allegory of justice, and a skeleton with a scythe is an allegory of death.

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.
