Answer:
A
Explanation:
Plagiarism is when you copy from another source without giving credit to it. It's a form of academic dishonesty because you're trying to pass off someone else's work as your own.
Your thesis could be (since this is about sports) “This sport is important because ______________.(whatever sport your writing about) and also because ________.
The subject would be "the ball." The subject in the sentence is the person, place, or thing. In this case the ball would be the subject because it's the most mentioned in the sentence, and also it's the first thing that comes into mind when your reading the sentence, the BALL hits a goal post and then the BALL bounced off.
Hope this helps!
