Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 39 to 43.

Stephen Hawking is one of the most famous scientists in the world today. He uses mathematics to study space and the universe. He has written several famous books. He wrote A Brief History of Time in 1988, and more than 10 million people have bought this book. Other scientists have called Hawking the greatest scientist in the world.

Hawking has faced terrible problems in his life. When he was 21, he got a serious disease called ALS. It quickly got worse, and soon he couldn't walk or speak. Now he can move only his left hand. He uses a wheelchair with a motor to get around. He "talks" by typing words into a computer. The computer pronounces the words for him.

But for Hawking, his work is more important than his problems. Now he is interested in the beginning of the universe. He teaches at Cambridge University in England, and he gives lectures at other universities. He has written many important scientific papers and has won many prizes for his work. He has appeared in several movies and has been on TV many times. He has traveled in countries around the world, and he has even traveled in space! In 2007, he went up on a special zero- gravity plane.
