Question: Article: The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruits and green vegetables. It is only when people try to live on a very _ diet, say that when trying to lose weight, that it is necessary to make special provisions to supply the missing vitamins. An example of the dangers of a restricted diet may be seen in the disease known as "beri-beri", which used to make large numbers of Eastern people who lived mainly on rice suffer. In the early years of last century, a Dutch scientist named Eijkman was trying to discover the cause of beri-beri. At first he thought it was transmitted by a germ . He was working in a Japanese hospital, where the patients were fed on polished rice which had had the outer coverings removed from the grain, it was thought this would be easier for weak and sick people to digest. Eijkman thought his germ theory was proved when he noticed the chickens in the hospital yard, which were fed on remains from the patients' plates, were also showing signs of the disease. He then tried to separate the germ, which he thought was causing the disease, but his experiments were interrupted by a hospital official, who ordered that the rice without coverings, even though left over by the patients, was too good for chickens. It should be recooked for the patients, and the chickens should be fed on cheap, rough rice with the outer coverings still on the grain. Eijkman noticed that the chickens began to recover on the new diet. He began to consider the possibility that eating unmilled rice somehow prevented or cured beri-beri--even that a lack of some ingredient in the coverings may be the cause of the disease. Indeed this was the case. The element needed to prevent beri-beri was shortly afterwards separated from rice coverings and is now known as vitamin B. The milled rice, though more expensive, was in fact causing the disease the hospital was trying to cure. Nowadays, this terrible disease is much less common thanks to our knowledge of vitamins.

Options: (A) It killed large numbers of people. (B) It resulted from lack of vitamins. (C) It was transmitted by milled rice. (D) It was caused by diseased chickens.

Question: Article: A shopkeeper sent his son to learn about the secret of happiness from the wisest man in the world. The boy walked a long way, and finally came upon the beautiful castle where the wise man lived. On entering the main room of the castle, the boy was quite surprised: tradesmen coming and going, people chatting in the corners, and a small orchestra playing soft music. The wise man talked with everyone, and the boy had to wait for two hours before it was his turn. The wise man listened carefully to the boy's explanation of why he had come, but told him that he didn't have time just then to explain the secret of happiness. He suggested that the boy look around the palace and return in two hours. "Meanwhile, I want to ask you to do something," said the wise man, handing the boy a teaspoon that held two drops of oil. "As you wander around, carry this spoon with you without allowing the oil to spill." The boy began to walk up and down stairs of the palace, keeping his eyes fixed on the spoon. After two hours, he returned to the wise man. "Well," asked the wise man, "Did you see the Persian tapestries in the hall? Did you see the garden that took the master gardener ten years to create?" The boy was embarrassed, and replied that he had observed nothing. His only concern had been not to spill the oil. "Then go back and observe the wonders of my world," said the wise man. The boy picked up the spoon and returned to his exploration of the palace. This time he observed all of the works of art on the ceilings and the walls. When he returned, he described in detail everything he had seen. "But where are the drops of oil?" asked the wise man. Looking down at the spoon he held, the boy saw that the oil was gone. "Well, there is only one piece of advice I can give you," said the wise man. "The secret of happiness is to see all the wonders of the world, and never to forget the drops of oil on the spoon."
Question: When the boy arrived at the castle, he _ .
Options: (A) received a warm welcome from the wise man (B) had already missed his chance to talk to the wise man (C) was shown around the palace by the local people (D) didn't expect to see so many people around

Question: Article: Jogging has become the most popular individual sport in America. Many theories,even some mystical ones,have been advanced to explain the popularity of jogging. The plain truth is that jogging is a cheap,quick and efficient way to maintain (or achieve) physical fitness. The most useful sort of exercise is exercise that develops the heart,lungs, and circulatory systems. If these systems are fit,the body is ready for almost any sport and for almost any sudden demand made by work or emergencies. One can train more specifically,as by developing strength for weight lifting or the ability to run straight ahead for short distances with great power as in football,but running trains your heart and lungs to deliver oxygen more efficiently to all parts of your body. It is worth doing that: this sort of exercise is the only kind that can reduce heart disease, the number one cause of death in America. Only one sort of equipment is needed--a pair of good shoes. Physicians advise beginning joggers not to try to run in tennis or gym shoes. Many design advances have been made in only the last several years that make a pair of excellent running shoes indispensable if a runner wishes to develop as quickly as possible,with as little chance of injury as possible. A pair of good running shoes will have soft pads for absorbing shock, as well as slightly built-up heels and full heel cups that will give the knee and ankle more stability. A wise investment in good shoes will prevent blisters and the foot,ankle and knee injuries and will also enable the wearer to run on paved or soft surfaces. No other special equipment is needed; you can jog in any clothing you desire,even your street clothes. It takes surprisingly little time to develop the ability to run. The American Jogging Association has a twelve-week program designed to move from a fifteen- minute walk (which almost anyone can manage who is in reasonable health) to a thirty-minute run. A measure of common sense,a physical examination,and a planned schedule are all it takes.
