This isn't a homework question but why doesn't allow links? I was trying to post one earlier today because it was a watch the video and answer the questions type of question, but it kept deleting my question and saying it wasn't allowed? Why?

That is a good question I was wondering the same thing.

Explanation:

id say it means hes fearful and/or cautious

have a good day

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.
