If you turn in a homework assignment that isn't yours and cheat on the exam, would it be a lie or not?

Answer 1

Yes, it is a lie. Homework assignments and exams are typically used as a way to show what you have learned about a concept. Turning in another person's work or cheating on an exam is lying to the teacher because you are claiming to have completed something independently that you, in fact, did not. It is also lying because you are trying to prove that you have learned a concept that you really may not have learned.
