An extended metaphor is developed a. over several sentences in a text b. quickly and used only once in a text c. at the beginning and the end of a text d. and used only in one paragraph or stanza

It'd be a cause;a comparison between two unlike things that continues throughout a series of sentences in a paragraph, or lines in a poem.

A. over several sentences in a text.

people are gonna need the passage.

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.
