Q: Article: With America's national debt continuing to climb, Congress is constantly debating ways to save money. The Dollar Coin Alliance, a lobbying group, says billions could be saved if dollar coins were used instead of paper bills. But many people won't use them. The U.S. government tried to push dollar coins again in recent years, but then suspended almost all production in 2011. American likes paper dollars, but Jim Kolbe, co-chairman of the Dollar Coin Alliance, thinks switching to the coin is worth it. "The coin does cost more to produce, roughly on the neighborhood of 17 cents versus the 5 or 6 cents that a paper dollar costs to produce," he said. "However, the coin lasts 35 years, and it's made of mostly recycled metals, and the paper has to be produced from new materials, and we shred 3 billion of those every year because they wear out." For years, the former Arizona congressman has been pushing legislation that would prop up the dollar coin by phasing out the greenback -- a move that has met resistance from both politicians and the public. But today, he said, _ and a recent poll indicates 61 percent of Americans like the idea. "When they learn of the savings that can be involved with this, they will support the idea of substituting the coin for the paper dollar," he said. Major savings Kolbe points to a study by the Government Accountability Office, which investigates how the government spends taxpayer dollars. The GAO estimates taxpayers would save more than $4 billion over 30 years, and that figure could be much higher. That appeals to taxpayer Christy Thompson, who said, "I'd probably say, yes, we need to do it." But plenty of people aren't convinced, including Kim Doering of Alexandria, Virginia. "It's easier to carry the paper bill than a bunch of coins. They're louder; they're heavier in your pocket," she said. Washington, D.C. restaurant owner Sue Fouladi doesn't like the idea of having more dollar coins in her cash register. "It's very inconvenient," she said. "If I don't have a choice, then I'll do it, but I'll be a very unhappy person." Adding to the problem is that the gold- and silver-colored metal coins are about the same size as the 25-cent quarter. Robert Blecker, an economics professor at American University in Washington, says the dollar coins should be a different size and thickness. "And if we can design a dollar coin that's not so big and bulky, probably Americans would like it better," he added. But that doesn't bother college student Emily Sturgill. "Sometimes they fit into your pocket easily and you don't have to worry about them slipping out, like a dollar bill would if you brought your keys or your phone out," she said.

Options: (A) They cost less than paper bills . (B) They are convenient to carry. (C) They are not easy to wear out. (D) They are produced from new materials.

Q: Article: Harvard University in the United States has been ranked as the university with the best "reputation" in the world. The Times Higher Education magazine has listed 200 top universities all over the world based on how they are regarded by a group of international college teachers. That is to say the list measures how universities are regarded, rather than how they actually performed. A subjective, word-of-mouth quality such as "reputation" has genuine economic value for universities, said Simon Marginson, professor of higher education at the University of Melbourne in Australia. "Reputation is not just an impression, though it might be not as reliable as performance by objective indicators ," said Prof Marginson. Based on the views of 13,000 college teachers around the world, it confirms the power of the big US universities, which _ this list. Seven of the top 10 are US universities, headed by Harvard and Massachusetts Institute of Technology (MIT). Furthermore, 14 of the top 20 are from the US. Cambridge is the highest ranking UK university in the list, in third place, with Oxford ranked as sixth. For students applying to university, reputation might be hard to quantify, but was an important part of the attractiveness, said the president of Cambridge University's students' union, Rahul Mansigani. "Reputation makes a huge difference. If there is an idea that somewhere is great, it will get lots of good people applying whether it's true or not. Factors such as a sense of history and the presence of outstanding college teachers were part of the reputation of Cambridge," he said.
Question: What can be inferred from the text?
Options: (A) No Asian universities are among the Top 10. (B) At least five UK universities are among Top 20. (C) The Times Higher Education magazine is from the US. (D) Reputation affects students' decisions when choosing universities.

Q: Article: Ideas about education are changing in the United States. Education today is not just a high school diploma or a college degree. Many adults are not interested in going to college.

It also gives them a chance to improve their old skills or to learn new ones. If they know more or learn more, then they can get a better job or earn more money.

There are many chances for adults to continue their learning. Almost any community college or public school system has a continuing education program. There are classes in schools, buildings, or churches. Most classes are in the evening, so working people can attend. The classes are usually small, and they are inexpensive.
