In my opinion,  the benefits of videotaping yourself practicing your speech is you are able to make sure you are speaking loud enough. Also, you are able the see if your speech is consist and clear. Another thing is that to make sure that you sound lively.

Explanation:

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.
