What is the main purpose of haratio’s speech?

The purpose is to persuade the gathering of people of the truth of the ghost that has showed up before Marcellus and Barnardo on two earlier evenings. He is the suspicious logician who does not trust in ghostly visions and unquestionably not in phantoms, and when he is persuaded that a heavenly being has appeared to him and his associates, the gathering of people are persuaded also.

type of error:

the error in the sentence is a "dangling modifier". a dangling modifier is a phrase, word or clause that "dangles" because there is not target to modify. in this case, "after mopping the floor" is the dangling modifier since it has no word to modify. the noun "house" cannot mop the floor; therefore there is a mistake in the writing of the sentence.
