Pls I really don’t wanna go to summer school

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.

no. but, i heard its a good book. you could look up the answers or summary on some website.

answer is b "guaranteed the safety of any merchant"
