He has made wigs for the stars of more than seventy movies ,including Tom Hanks in Philadelphia, Johnny Depp in Sleepy Hollow and Nicole Kidman in The Others. One of his biggest jobs so far has designed the hair and makeup for the three Lord o f the Ring movies . He had just six weeks to design and make more than a hundred wigs, each one a different style, color, shape and length. The hair and makeup in a movie are just as important as the costumes or the sets. Over the years, Peter has made actors look older, younger, healthy and sick. For one movie he even made a female actor look like a man! "What people don't realize about wigs is that we are not always making people more beautiful," he says. "Often we are covering up beauty and making them look ordinary." All Peter's wigs are handmade using human hair, so they look as real as possible. This also makes them very expensive -between US $ 4,500 and US $12,500 each! He knows he's done a good job when people don't realize the star of the movie is wearing a wig. So he was pleased when one newspaper said that Nicole Kidman had dyed her hair dark brown for a movie. "It was a wig and no one knew that9" he said. Options: A They are made in foreign countries. B Peter makes the best wigs. C They are only made for rich film makers. D They are handmade using human hair. Answer: D They are handmade using human hair. Question:

Problem: Given the question: Write a multi-choice question for the following article, with the given choices and answer: Article: When did you last see a polar bear? On a trip to a zoo, perhaps? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in winter to swim in freezing cold water. That day, air temperature was 3degC, and the water temperature was a bit higher. The members of the Polar Bear Club at Coney Island , New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group, this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February. Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so low that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter. The Polar Bears themselves are satisfied with the benefits(or advantages) of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming. The main benefits(or advantages) of cold-water swimming are probably mental . The Polar Bears love to swim year-round; they find it fun and relaxing. As one 70-year-old woman says,"When I go into the water, I pour my troubles into the ocean and let them float away ." Options: A they can remain young B it is an easy way to keep the body warm in winter C they find it enjoyable and interesting D they might meet fewer troubles in life Answer: C they find it enjoyable and interesting Question:
