A. inform

This text is providing you facts. The statements are falsifiable (they can be checked to see whether they are true or not) and do not persuade you of any position or opinion. They are also not entertaining or confrontational. The only purpose of the text is to inform you of a reality.

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.
