Explanation:

In writing an effective sentence, the need to refrain from using too much of "to" or "do" in the sentence makes it an unnecessary or too common sentence. Rather, the use of more effective verbs will make the sentence more precise and effective.

In the given sentence, "did a good job" is a good way of talking about the verb but replacing it with "spoke eloquently" provides a more effective structure and verb use.

So, the correct answer is the second option.

a. is the correct answer

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.
