well for some you have to do on your own on a paper but yeah

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.

in my opinion, ap calculus was the most difficult. i often struggled with it a lot. however, i have gotten a lot better.

they are direct opposites. they can both be corrupted. they are inseparable.
