Novak Djokovic questions

 Today I had to read an article about how Novak Djokovic hit a line judge in the neck while playing tennis then answer the questions.
It was slightly hard when I had to watch the video about it because I didn't actually understand anything he was saying.
To be BTB I could have written longer answers.

Read this article and then answer the questions below in full sentences. 

What did Novak Djokovic do to make him default from the US open? He was angry because he lost his last game, so he hit the ball very hard behind him. The ball hit the line judge's neck, causing pain.

What rule did Djokovic break? The rule that says you can’t intentionally hit a ball dangerously or recklessly in the court or hit a ball with negligent disregard of the consequences.

Do you agree with Djokovic’s punishment? Why? Explain. Yes. He made someone not be able to breathe and hurt them.

Watch the video in the article. Do you agree with what the man said? Explain. Yes, I agree with what he said. He hit the ball and hurt someone, and the man says it makes sense that he should get defaulted and I think that makes sense too.
Also, in other sports, people starting fights or hurting people get sent off. 

Should professional sportsmen and women let their emotions get the best of them while playing? Explain. No, they shouldn’t. They might hurt someone and get physical, and they wouldn’t be role models for any children that like to watch tennis.
