Read the following article and select the best answer. Article: Many Americans concerned about pollution are demanding cleaner supplies of energy. The demand has resulted in increased research about ethanol fuel. Ethanol is an alcohol that can be mixed with gas. It burns up most of the pollutants in gas. It replaces some of the chemicals that are known to cause cancer, and it can be produced in the United States. Some experts say that in the future ethanol will replace some of the oil imported into America. Today ethanol is less than one percent of total American fuel supply. The head of the National Corn Growers Association, Kieve Hard, says ethanol will provide twenty-five percent of the fuel supply by 2030. The organization is involved in the production of ethanol because it can be made from corn. One company in the American Midwest says it is starting to produce ethanol because of demands from people and from the government. The Congress approved the Clean Air Act in 1990. The company says this means the market for ethanol will expand. The company is a major producer of corn starch that can be used to make ethanol. At Texas A and M University Professor Mark Holzapple produces ethanol from materials found in solid waste. He has developed a way to turn materials like paper into simple sugar. He then uses yeast to turn the sugar into ethanol. Professor Holzapple says two hundred liters of ethanol fuel can be produced from one ton of solid waste. A professor at the University of Arkansas, John Geddie, is exploring another way to make ethanol. He is using acids on paper material. He says a large factory could produce ethanol from waste paper at a cost about the same as the cost of producing gasoline. Environmentalists support the use of ethanol because it turns solid waste into a useful product. Professor Holzapple says law makers in industrial nations need to support the development of this clean, less expensive fuel of the future. Question: In this passage, what is the significance of the Clean Air Act passed by American Congress in 1990? - It will increase the consumers' demand for ethanol as a fuel. - It may increase the cost of producing gas. - It reflects the view of the government on automobiles production. - It limits the ethanol production of one company in the American Midwest.
It will increase the consumers' demand for ethanol as a fuel.

Read the following article and select the best answer. Article: Tug-of-war is not only popular in China, but in many other countries. Their tug-of-war match is a little different from ours. They have eight players for each team, while we may have the match between two sides with equal men or women players. Of course, they are usually tall, strong and heavy. For a tug-of-war match, we need a long thick rope. Each team stands at one end of the rope, holding it. Then they try to pull the center of the rope, marked in the ground towards each of their own sides. The team which succeeds in pulling the center of the rope away through a certain distance is the winner. Many foreign sport experts think we don't have to be tall, heavy and strong to play tug-of-war. We needn't have endless energy, for a match lasts only a few minutes. The secret is good hands. The players must have big, strong and hard hands. Before they start the match, they put a mixture of oil and petrol on their hands so they can hold the rope better. Many foreign experts say the best hands for tug-of-war belong to the sons of farmers. This is because they have to work hard when they are still very young. Farming is a good practice for this sport! Question: The foreign experts think a good tug-of-war player must _ . - have lasting energy - have big, strong and hard hands - do farm work - be tall, heavy and strong
have big, strong and hard hands

*Question*
Read the following article and select the best answer. Article: "I feel fat." "I hate my hair." "I wish I were taller." Julia Bluhm, 14, was sick of hearing comments like these. Many girls she knew seemed to worry too much about their appearance -- their weight, skin, hair, even the shape of their faces. So Julia decided to do something about it. Her target? Seventeen, a popular girls' magazine. "I look at the pictures, and they just don't look like girls I see walking down the street," the eighth-grader from Maine told The New York Times. Of course they don't. Magazines use programs like Photoshop to remove zits , add shine to hair, and slim waistlines. Often, girls are made to look like Barbie dolls. Julia fears that these impossible standards of beauty make teens feel terrible about their own appearances. After all, even the models aren't as perfect as they look in print! So Julia launched an online petition asking Seventeen to put at least one unaltered photo in each issue. "I want to see regular girls that look like me in a magazine that's supposed to be for me," she wrote. Days later, her petition had thousands of signatures. Julia and her mom traveled to New York City and joined a demonstration in front of Seventeen' s offices. Then they were invited to meet with Seventeen's editor-in-chief, Ann Shoket. A few months later, Shoket announced that the staff of Seventeen had signed a "Body Peace Treaty." They promised to "never change girls' body or face shapes" and only use photos of "real girls and models who are healthy." In addition, they promised to be more open about the ways in which images are changed before publication. Julia's fight against teen self-hate is far from over, but for now it seems she's winning -- and she's thrilled. "This is a huge victory," she wrote in a message on her petition page. "I'm so unbelievably happy." Question: Why did Julia launch an online petition? - To fight for real beauty. - To join a demonstration. - To set a standard of beauty. - To ask Seventeen to apologize.
