Read the following article and select the best answer. Article: Once upon a time there lived the daughter of a king. Her name was Safia. Her father and mother loved her very much, and would deny her nothing in the world. One day, a magician came to the palace and asked for sanctuary , saying that he was a professor who was being persecuted by his enemies and had nowhere to write an important book. "Good professor," said the king, "you shall have a room and everything that you desire, on condition that you may finish your great work." So the magician went on with his spells and magic formulas, pretending to be absorbed in scholarly matters. Every Friday, which was the day of rest in that far land, the magician paid his respects to the king and his court, but secretly he desired to take away the king's throne. One day he disguised himself as an old woman and walked under the trees in the palace gardens till he met Safia. "Princess," he said, "let me be your laundress, for I can wash linens and silks as finely as anyone in the world, and I would do it for almost nothing if I could serve Your Highness." "Good woman," said Princess Safia, "I can see that you are a poor creature and grieve for your condition. Come to my private quarters and I shall give you some of my linen to wash." So the disguised magician followed the princess into the palace, and before the girl could see what was happening he bundled her into a laundry bag and ran away as fast as his legs would carry him. He took the princess into his private room. Muttering a magic spell, he made her as small as a doll, and put her in a cupboard. The next Friday he went to the court as usual, and found the whole palace _ "Princess Safia has vanished, and His Majesty is nearly out of his mind. All the soothsayers have tried to find out through their magical powers where she can be, but none of them have managed it," said the Grand Vizier. The wicked magician smiled, for he knew that his spell was so strong that it would defy all the soothsayers in the land until the day of his death. Question: We know from the passage that Safia _ . - was the only child of the king - was fond of magic - didn't refuse the old woman's request - didn't live in the palace
didn't refuse the old woman's request

Read the following article and select the best answer. Article: "I drink caffeine to stay awake. It has positive effects on me. I'm healthy, and there's nothing wrong with me," said Sarah Green, a freshman, who consumes many caffeine drinks to stay awake in completing the many tasks in her busy schedule. Caffeine is known to have many positive and negative consequences, and now that there might be an additional positive effect may have been discovered. A study suggests that a skin lotion containing caffeine, which is also found in green tea, may reduce the risk of skin cancer. Two lotion tests were conducted on hairless mice that were exposed to high levels of ultraviolet radiation . As a result, the lotion reduced the number of tumors each mouse developed. Unlike sunscreen , the new lotion is applied after exposure to the ultraviolet rays. Rays from the sun can cause genetic changes in the skin that can lead to skin cancer. Caffeine obstructs this action and causes the diseased cells to kill themselves. "I know that caffeine has been found in certain drinks and it causes increased activity of the nervous system, and increased blood pressure on blood vessels . I don't know of any positive effects of caffeine," health teacher Montego Estes said. Caffeine, found commonly in tea, coffee and soft drinks, provides people with an increase in energy. Half of all American adults consume more than 300 milligrams of caffeine per day. Caffeine is addictive because it uses the same mechanisms as amphetamines , and cocaine and heroin to excite the brain. "This new cream doesn't sound to me as though it would work," junior David Bobbit said, "Caffeine seems to have more negative effects than positive ones." Skin cancer is the most common of all cancers in the US. About one million cases will be diagnosed in the country this year. There will be more than 88,000 new cases of melanoma , the disease's deadliest form of skin cancer. Question: What is the main idea of this passage? - Many Americans like Sarah Green enjoy drinking caffeine. - Hairless mice are not easily harmed by ultraviolet radiation. - Research shows caffeine may reduce the risk of skin cancer. - Americans suffer most from skin cancer among all cancers.
Research shows caffeine may reduce the risk of skin cancer.

Article: The Dangers of Dieting Thanks to our modern lifestyle, with more and more time spent sitting down in front of computers than ever before, the number of overweight people is at a new high. As people crazily search for a solution to this problem, they often try some of the popular fad diets being offered. Many people see fad diets as harmless ways of losing weight, and they are grateful to have them. Unfortunately, not only don't fad diets usually do the trick, but they can actually be dangerous for your health. Although permanent weight loss is the goal, few are able to achieve it. Experts estimate that 95 percent of dieters return to their starting weight, or even add weight. While the irresponsible or unwise use of fad diets can bring some initial results, long-term results are very rare.[:**] Nonetheless, people who are bored with the difficulties of changing their eating habits often turn to fad diets. Rather than being moderate, fad diets involve extreme dietary changes. They advise eating only one type of food, or they prohibit other types of foods entirely. This results in a situation where a person's body doesn't get all the vitamins and other things that it needs to stay healthy. One popular fad diet recommends eating lots of meat and animal products, while nearly eliminating carbohydrates . A scientific study from Britain found that this diet is very high in fat. According to the study, the increase of damaging fats in the blood can lead to heart disease and, in extreme cases, kidney failure. Furthermore, diets that are too low in carbohydrates can cause the body to use its own muscle for energy. The less muscle you have, the less food you use up, and the result is slower weight loss. Veteran dieters may well ask at this point, "What is the ideal diet?" Well, to some extent, it depends on the individual. A United States government agency has determined that to change your eating habits requires changing your psychology of eating, and everyone has a different psychology. That being said, the British...
