i cant see the passage although i do know hyperbole means overly exaggerated such as "i can eat an enter horse"! i hope this you!

the chivalry's most valued code is morality

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.
