I'm taking a test and have to guess the right answer to the question after the article. Article: Spending as little as $5 a day on someone else could significantly boost happiness, the team at the University of British Columbia and Harvard Business School found on Thursday. Their experiments on more than 630 Americans showed they were measurably happier when they spent money on others--even if they thought spending the money on themselves would make them happier. "We wanted to test our theory that how people spend their money is at least as important as how much money they earn," said Elizabeth Dunn, a psychologist at the University of British Columbia. They asked their 600 volunteers first to rate their general happiness, report their annual (yearly) income and detail their monthly spending including bills, gifts for themselves, girls for others and donations to charity. "Regardless of how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not," Dunn said in a statement. Dunn's team also surveyed 16 employees at a company in Boston before and after they received an annual profit-sharing bonus of between $3,000 and $8,000. "Employees who devoted more of their bonus to pro-social spending experienced greater happiness after receiving the bonus and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself" they wrote in their report, published in the journal Science. They gave their volunteers $5 or $20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it. "These findings suggest that very minor alterations (changes) in spending allocations (shares)--as little as $5--may be enough to produce real gains in happiness on a given day,"Dunn said. Question: Which of the following statements is NOT true according to the passage? Options: A: Those who spend more money on others can get much more bonus. B: People usually think spending money on themselves will make them happier. C: Very small changes in spending your money may be enough to gain happiness. D: Researchers think that how people spend their money is at least as important as how much money they earn.

I'm taking a test and have to guess the right answer to the question after the article. 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? Options: A: It needs the cooperation of many chemists. B: It associates with the use of advanced equipment. C: It will improve the use of heat from exhaust gases. D: It requires the support of the government.
