Write a multi-choice question for the following article: Article: We are always attracted by the sea. From it we can get food, minerals and treasures. For thousands of years, we just sailed on it but couldn't go far under its surface. We want to explore deep into the sea. However, we are not fish. We must breathe, so we can't stay underwater for long. To explore deep water, we face even more dangers and problems. A diver trying to stay underwater for a long time must breathe air or a special mixture of gases. He can wear a diving suit and have air pumped to him from above. He can carry a tank of air on his back and breathe through a special pipe. Water weighs 800 times as much as air. Tons of water pushes against a diver deep in the sea, so his body is under great pressure. When a diver is under great pressure, his blood takes in some of the gases he breathes. As he rises to the surface, the water pressure becomes less. If the diver rises too quickly, the gases in his blood form bubbles . The diver is then suffering from a kind of illness. This kind of illness can cause a diver great pains and even kill him.

Write a multi-choice question for the following article: Article: Before I started school, people felt that I was not going to be successful. At the age of four I started speech lessons because basically I could not speak well enough for anyone to understand me. The story goes downhill from here. The first grade was a struggle. I not only had difficulty speaking, but also felt nervous about the fact that I was expected to learn to read and I just couldn't do it. The second grade was not much better. I still struggled with the inability to read. It was in the third grade that the school district built a new school close to my home. I remember going there with my parents and helping to get the school ready so that we could move to the new one. However, things were still not much better as far as my schooling was concerned and did not get better for the next two years. It was in the fifth grade. Mrs. Wakefield was my teacher, and if ever there was a teacher that deserved a gold star, it was her. She did not make me feel defeated. On the contrary, she did her best to let me know that I could be whatever I wanted to be. And that is just what I did. For the past 22 years, I have been a fifth grade teacher. Because of Mrs. Wakefield's influence on my life, I am now encouraging students who have had difficulties in their lives to believe that they can overcome any difficulty and become someone. I have won numerous awards up to now, such as Teacher of the Year. I owe it all to one fifth grade teacher who believed in me and challenged me to be all that I could be.
