Write a multi-choice question for the following article: Article: When I was eight years old, I had a big accident. I get scared even now when I think about that time. There were many people skating near my house, and seeing them skate so wonderfully, I couldn't wait to have a try, just a piece of cake, I thought . I went with a friend who was very skillful. He spent a long time teaching me how to skate , but I still didn't learn much , which made him very angry. Finally , he left me and skated all around. I skated alone and soon got bored because I kept falling down so I took off my skates and just walked around on the ice in my shoes. It was cold and my feet were frozen. Suddenly, I stepped on something that was not hard. What was it ? It was a weak place in the ice . When I stepped there, I sank under the ice. I thought that I was going to die, but I did my best to grab something to get out from under the ice. I would have climbed out myself by grabbing the edge of the ice, but at that time I was only a child of eight . I cried out. Fortunately, someone helped me. He grabbed my arms and pulled me up. Those several minutes seemed a year to me. I thanked him. At that time, my friend came back. I was annoyed at him because he was supposed to take care of me, but he didn't. He was embarrassed. When I took a taxi home, the taxi driver was surprised and asked what had happened. I didn't want to say anything because I was tired and scared. Since then, I have never touched skating.
