user: Ques: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: What does Professor Mark Holzapple think of the development of ethanol in countries? - It needs the cooperation of many chemists. - It associates with the use of advanced equipment. - It will improve the use of heat from exhaust gases. - It requires the support of the government.

Ans:It requires the support of the government.

Zach gave Bradley a few driving tips: Don't drive next to big trucks, because you never know when they might crush  you. Don't drive behind trucks filled with things, because you never know when something in the truck will fly out and hit your car. On their way back, Zach suggested that they stop at the golf course. He wanted to show Bradley how to play golf. Bradley wasn't interested. He preferred his video games. But Bradley soon discovered that golf was fun! He hit a lot of balls. Zach told him that he was doing well. The next day Bradley, for the first time ever, called Zach. He had a few blisters  on his hands. Zach said that usually happened. Then Bradley asked if Zach would come next Saturday so they could take a drive and hit golf balls again. Zach said, of course, and felt happy.

Ques:Read the following article and select the best answer. Article: It's impossible to determine how many people would have lost their lives without the contribution of African-American inventor Dr Charles Drew. Charles Drew was born on June 3, 1904, in Washington, DC. His early interest was in education, but he was also an outstanding athlete. While in college, he was awarded as the man who contributed the most to sports during his four years in school. Drew's sister Elsie suffered from tuberculosis  and died in 1920. Her death influenced his decision to study medicine. After becoming a doctor and working as a college instructor, Drew went to Columbia University, where he earned his Doctor of Medical Science degree. During this time he became involved in research on blood and blood transfusions. At Columbia, he wrote a paper on "banked blood", in which he described a technique he developed for the long-term preservation of blood plasma. Before his discovery, blood could not be stored for more than two days because of the rapid breakdown of red blood cells. Drew had discovered that by separating the plasma from the whole blood and then refrigerating them separately, they could be combined a week later for a blood transfusion. Drew became the first African American to receive a PhD in medical science. After World War II broke out, Drew was called upon to put his techniques into practice. He was named a project director for the American Red Cross but soon quit his post after the government issued an order that blood taken from white donors should be separated from that of black donors. On April 1, 1950, after he attended the annual free clinic at the John A. Andrew Memorial Hospital, he and other three physicians decided to drive back home. As he was tired from spending the night before in the operating room, he lost control of his car. Drew was badly injured and was taken to Alamance General Hospital in Burlington, North Carolina. He was pronounced dead half an hour after he first received medical attention. Drew's funeral was held on April 5, 1950, at the Nineteenth Street...
