I am assuming that this question is asking you to correct this sentence. Here is the revised sentence: "You forgot that you took my blanket too."
C. The auther uses humor to decide the issue for themselves.
This is a complex sentence which consists of a dependent or subordinate clause and an independent clause.
'If you finish your yard work' -- dependent clause
'you can take the car to the movie' -- independent clause.
Can you explain more please explain more questions
