Article: A young man was going to join the army and had to take a medical examination. The doctor was sitting at a desk when he went in. He said to the man. "Take your coat and shirt off, and sit on the chair." The young man did so. The doctor looked at him for a moment without getting up from his chair and then said, "All right. Put on your clothes again." "But you haven't examined me at all!" the young man said in surprise. "There is no need to do so," the doctor said with a smile. "When I told you to take your coat and shirt off, you heard me all right, so there is nothing wrong with your ears. You saw the chair, so your eyes are good. You could take your clothes off and sit on the chair, so you must be in good health. And you understand what I told you to do and did it without a mistake, so you must be clever enough for the army." Question: At first the young man _ . Yes or no, is the answer "did not understand what the doctor mean"?

Article: In his 1930 essay "Economic Possibilities for Our Grandchildren ", John Keynes, acconmist, ewrote that human needs fall into two classes: needs ,which are indupe what other have , and needs ,which make us feel superior to our fellows He thought alough needs may indeed be insatible this isnottrue of Keynes wans surely correct that only a small part of total spending id decided by the super iority He was gretly mistaken ,however ,in seeting this desive as the only source of demands Decisions to spend are also driven by ideas of quality which can influnce the den almost all goods, including even basic goods like food. When a couple goes out for an anm dinner,for example,the thought of feeling superior to others probably never comes to them. The goal is to share a special meal that stands out from other meals. There are no obvious limits to the _ of demand for quality.For example ,porsche famous car producer,has a model which was considered perhaps the best sport car on the mark Priced at over $120,000,it handles perfectly well and has great speen acceleration.But in 200 the producer introduced some changes which made the model slightly better in handling acceleration.People who really care about cars find these small improvemenmts exciting.To them,however,they must pay almost four times the price. By placing the desire to be superior to other at the heart of his description of nisation demands,Keynes actually reduced such demands.However,the desire for higher quality has natural limits. Question: The author of the passage that _ . Yes or no, is the answer "needs have no limits"?
No

Q: Article: As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. The they become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (, ) in science. Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry . These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute. Of course, scientists cannot answer all of our questions. If we ask, "Why does the ocean water taste salty?" Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , "What happens to the salt in the ocean? The ocean does not get saltier every year." Scientists are not sure about the answer to this question. We know a lot about our world, but there are still many answers that... Question: When you run, your muscles need _ . Yes or no, is the answer "more nutrition and oxygen"?
A: No

*Question*
Article: Right now, 62 million girls worldwide are not in school. They're receiving no reading, no writing, no math--none of the basic skills they need to provide for themselves and their families, and contribute fully to their countries. Often, understandably, this issue is considered as a matter of result of a failure to invest enough money in educating girls. We can solve this problem, the argument goes, if we provide more scholarships and safe transportation and build more school bathrooms for girls. And it's true that investments like these are important for addressing our global girls' education crisis. But we cannot solve our girls' education problem until we deal with the broader cultural beliefs and practices that can help cause this crisis and make it continue. We know that legal and cultural change is possible because we've seen it countries around the world, including our own. A century ago, women in American couldn't even vote. Decades ago, it was perfectly legal for employers to refuse to hire women. But in each generation, brave people -both men and women--stood up to change these practices. They did it through individual acts like taking their bosses to court and even through national movements that brought changes. Cultural changes like these can encourage countries to make greater investments in girls' education. And when they do, that can cause a powerful effect that can cause even greater cultural and political progress for women. Girls who are educated marry later. Educated girls also can earn higher salaries. And when educated girls became healthy, financially secure, empowered women, they're far better equipped to achieve their needs and wishes, and challenge unjust laws and harmful practices and beliefs. But for me, this issue isn't just about politics or economics --- for me, this is a moral issue. As I've traveled the world, I've met so many of these girls. They're so hungry to realize their promise. They walk for hours each day to school, learning at rickety desks in bare concrete... Question: According to the passage, millions of girls _ . Yes or no, is the answer "are receiving no formal education"?
**Answer**
No
