I'm taking a test and have to guess the right answer to the question after the article. Article: At age 61, identical twins Jeanne and Susan no longer look exactly alike. Susan smoked for many years and is an admitted sun worshipper, whose habits Jeanne does not share. A new study of twins suggests you can blame those coarse wrinkles, brown or pink spots on too much time in the sun, smoking, and being overweight. Because twins share genes, but may have different exposures to environmental factors, studying twins allows an "opportunity to control for genetic susceptibility ," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and his colleagues explain in the latest issue of Archives of Dermatology. Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is related more to environment and lifestyle than genetic factors. But when it comes to skin cancer, the researchers say their findings support previous reports that both environment and genes affect skin cancer risk. Baron's team examined facial skin of 130 twins, 18 to 77 years old, who lived mostly in the northem Midwest and Eastern regions of the US, who were attending the Twins Days Festival in Ohio in August 2002. At this time, each of the twins also separately reported how their skin burned or tanned without sunscreen, their weight, and their history of skin cancer, smoking, and alcohol drinking. The study group consisted of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. From these data, the researchers noted strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental damage. By contrast, sunscreen use and drinking alcohol appeared related to less skin damage. Baron and his colleagues say the current findings, which highlight ties between facial aging and potentially avoidable environmental factors--such as smoking, being overweight, and unprotected overexposure to the sun's damaging rays--may help motivate people to minimize these risky behaviors. Question: The passage is mainly concerned with _ . Options: A: skin cancer and environment B: identical twins research C: aging skin and environmental factors D: genes and lifestyles

I'm taking a test and have to guess the right answer to the question after the article. Article: French people pride themselves on their delicious foods, such as cheese, baguettes and croissants(two kinds of food). In fact, food is an important part of French culture. Families and friends spend hours over the dinner table each night. It is the opposite of the fast-food habit common in other parts of the West. It's the reason why the French are very angry that a McDonald's is opening beneath Paris's most famous museum: the Louvre . The new restaurant will be the 1,142nd McDonald's in France, and will open in the underground approach to the museum. But many French people can't understand why this American chain is opening in the heart of French culture. However, McDonald's is paying no notice to the complaint. McDonald's now has 31,000 chains worldwide. Tourists are hungry, and opening chains in tourist spots pays well. There is another chain threatening France's heritage. This time it is coffee rather than burgers. As more and more Starbucks open in Paris, traditional French cafes are forced to close. The trouble with American companies opening chains throughout the world is the destructive effect they can have on a country's culture. How can a small, independent coffee shop compete with the multi-billion dollar chain? You can go to a Starbucks in any city in the world, but you can only go to a Parisian cafe in France. Responsibility is with the tourists. A McDonald's wouldn't open so near the Louvre if it weren't not going to make money. Similarly, a Pizza Hut wouldn't overlook Egypt's Great Pyramid if no one wants to sit in it. Maybe next time you visit the Great Wall, you should think twice before ordering a Cappuccino in the Starbucks. Question: The McDonald's will be located in the underground approach to the museum because _ . Options: A: the complaints of the French are useless B: opening a chain in tourist spot is rewarding C: McDonald's tends to be in the heart of culture D: it will help to attract more tourists for the museum

Ques: I'm taking a test and have to guess the right answer to the question after the article. Article: The price of milk may be going up. There was not enough rain in some parts of the country last year and the bad weather may mean that a gallon of milk will cost 41 cents more after October 1st. California already has high milk prices and the California court does not want the price to go any higher. High milk prices will be very hard for some people. Families with many children will have to spend more money to buy milk. The poor and older people without much money will also be hurt by higher prices. The court said that more milk from other states should be sold in California as the price of milk from other states is not as high. Some states got enough rain so their costs did not go up. People will then be able to buy the cheaper milk, meaning that unless milk producers bring their milk prices down, their milk will not sell. The drought around the country has meant market forces are likely to push milk prices up by as much as 41-cent a gallon by October 1st. Experts said this decision by the Californian court could reduce the effect of the price rise here. The 41-cent increase would add to California's already high milk prices so California must allow more milk producers from outside the state to sell their products there. This would then lead to increased supplies , which would, as a result, stop milk prices from increasing. Question: Who will be hurt by high milk prices? Options: A: Young people. B: Milk producers from outside California. C: Rich people. D: Families with lots of children.
Ans: D
Ques:I'm taking a test and have to guess the right answer to the question after the article. Article: At first, the earth's surface layer was made up of huge blocks of hard, solid rocks. Then slowly, the rocks broke up into smaller and smaller pieces. Finally stones, pebbles and grains of sand were formed. Many sorts of plants and animals lived and died on the surface of the earth. Their remains mixed up with the stones, pebbles and formed soil. The outmost layer of the earth is soil. There are many ways in which large pieces of rock break into smaller ones. Wind, water, heat and cold help to break up rocks. When winds blow grains of sand against a large rock for a long time, the softer layers of the rock are slowly worn away. These leave holes and cracks in the rock, which become bigger and finally the rock breaks up into smaller pieces. The moving water of streams and rivers also helps to break up rocks. As the water moves along, it carries with it small pieces of rock. These rub the larger ones. Thus, the larger rocks are worn down to smaller pieces. The heat of the sun is also helpful to breaking up rocks. When the sun shines, the rocks become very hot. If these rocks are suddenly cooled, they may crack. Ice also plays a part in making soil. Water in the cracks can turn into ice in cold weather. As this happens, it becomes bigger and the cracks become wider, and finally break into smaller pieces. Question: Which of the following speeds up the breaks of rocks most? Options: A: Hot weather. B: Cold water. C: Sharp changes in temperature. D: More dead plants in the cracks.
