explanation:

jack roosevelt robinson broke the color barrier in major league baseball.as he was the first african american to play in the major leagues, jackie robinson became the target of racial abuse. jackie robinson is referring to the historic event, harlem riot.

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.
