PROBLEM: 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.
Question: Which of the following is the advantage of dollar coins according to the passage?
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.

SOLUTION: C

PROBLEM: Article: We use both words and gestures to express our feelings, but the problem is that these words and gestures can be understood in different ways. It is true that a smile means the same thing in any language. So does laughter or crying. There are also a number of striking similarities in the way different animals show the same feelings. Dogs, tigers and humans, for example, often show their teeth when they are angry. This is probably because they are born with those behavior patterns. Fear is another emotion that is shown in much the same way all over the world. In Chinese and in English literature, a phrase like "he went pale and begin to tremble" suggests that the man is either very afraid or he has just got a very big shock. However, "he opened his eyes wide" is used to suggest anger in Chinese whereas in English it means surprise. In Chinese "surprise" can be described in a phrase like 'they stretched out their tongues!' Sticking out your tongue in English is an insulting gesture or expresses strong dislike. Even in the same culture, people differ in ability to understand and express feelings. Experiments in America have shown that women are usually better than men at recognizing fear, anger, love and happiness on people's faces. Other studies show that older people usually find it easier to recognize or understand body language than younger people do.
Question: According to the passage, _ .
Options: (A) we can hardly understand what people's gestures mean (B) we can not often be sure what people mean when they describe their feelings in words or gestures (C) words can be better understood by older people (D) gestures can be understood by most of the people while words can not

SOLUTION: B

PROBLEM: Article: Of all the areas of learning the most important is the development of attitudes. Emotional reactions as well as logical thought processes affect the behavior of most people. "The burnt child fears the fire" is one instance; another is the rise of figures like Hitler. Both these examples point up the fact that attitudes come from experience. In the one case the experience was direct and impressive; in the other it was indirect and gradual. The classroom teacher in the elementary school is in strategic position to influence attitudes. This is true partly because children acquire attitudes from those adults whose word they respect. Another reason it is true is that pupils often search somewhat deeply into a subject in school that has only been touched upon at home or has possibly never occurred to them before. To a child who has previously acquire little knowledge of Mexico, his teacher's method of handling such a unit would greatly affect his attitude toward Mexicans. The teacher can develop proper attitudes through social studies, science matters, the very atmosphere of the classroom, etc. However, when children come to school with undesirable attitudes, it is unwise to attempt to change their feelings by criticizing them. The teacher can achieve the proper effect by helping them obtain constructive experience. To illustrate, first-grade pupils, afraid of policemen will probably change their attitudes after a classroom talk with the neighborhood officer in which he explains how he protects them. In the same way, a class of older children can develop attitudes through discussion, research, outside reading and all-day trips. Finally, a teacher must constantly evaluate her own attitudes, because her influence can be harmful she has personal prejudices. This is especially true in respect to controversial issues and questions of which children should be encouraged to reach their own decisions as result of objective analysis of all the facts.
Question: The author uses the phrase "the burnt child fears the fire" in order to _ .
Options: (A) stress the importance of keeping child from the fire (B) exemplify the opinion that attitudes come from experience (C) illustrate the important role of attitudes towards study in the early childhood (D) none of the above
