In the passage below, how does the student know Ethan? ----- One day I was sitting in class and I read something scratched into my desk that said “Ethan is going to shoot up the school”. At first, I thought this was a joke and I didn’t take it seriously. I’ve known Ethan for years and he is a nice kid even though he gets bullied a lot. Later that night I was eating dinner with my mom and telling her what happened - my mom freaked out. My mom called the school and reported it. I went to school the next day and heard the principal call Ethan down to his office. I was nervous because I knew what was about to happen. I was talking to my friend Allie and her sister Kaylee about the whole situation and they were glad my mom called the school. I was annoyed that they agreed with my mom but I guess they had a point. Ethan did get bullied every day and he has seemed really upset lately. Later that night I got a call from Allie saying that she heard Ethan was arrested and had a hit list with over six people on it. I guess Ethan wanted to kill Tara, Nicole, Hunter, Kaylee, Sydney, Cameron, Rebecca, Tanner, and Taylor.     a) They have been friends for years b) They are a friend's sibling c) They are classmates
