Identify two examples of each:
assonance

1. like the night of cloudless  climes and starry skies

2. had half impaired the nameless grace which waves in every raven tress,

Explanation:

Assonance refers to the repetition of vowel sounds within a string of words. It creates a vowel rhythm. In the first example, there is a repetition of the 'i' vowel sound.

1. like the night of cloudless  climes and starry skies

The second example employs the repetition of the 'a' vowel sound thus;

2. had half impaired the nameless grace which waves in every raven tress,

in that passage i would say the sentence which best describes the overall impact of the setting is when they mention the absence of people because it suggests that taking a walk at night is unusual.

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.
