We liberals need to argue from Europe's self-interest: our continent has the need, the space and the ability to accept people. Many European countries are gradually turning into old people's homes. Germany, Italy, Spain and others have some of the lowest birth rates in human history. It is predicted that about one-third of their populations will be aged over 65 in 2050. Germany needs to import at least 350,000 people a year to keep its workforce stable. Suddenly, young ambitious workers are pouring into the country as if called by a genie with a lamp. No wonder Angela Merkel, German Chancellor, has been more welcoming than David Cameron, British Prime Minister. But all over Europe, carers for old people are already in need. Norway found oil under the seabed but it would have been better off if it had discovered 50,000 nurses there instead. Many rightwingers think we have reached our limits. This feeling is widespread. And it's true that Western Europe is one of the most densely populated regions on earth. Indeed, density has long been Europe's unique selling point: with so many people of different nations closely packed together, we have always traded goods and exchanged ideas fast. That's why the scientific revolution of the 16th and 17th centuries happened here. But we have plenty more room. Many European cities aren't dense enough. Now east Germany, north-western Spain and gorgeous mountain villages in Italy are losing people. Lots of cities have unused industrial land. Humans inhabit a slice of the EU's territory. Only about 2.5 per cent of the EU's land is used for housing, estimates the European Commission. By contrast, a whopping 43 per cent was used for agriculture in 2009, it says. That's too much. We could turn more land into forest or into green landscapes where people can relax and play. Making that transition is feasible because we now use agricultural land...

Options: A: nurses are more badly needed than petrol in Europe B: liberals always do something for the Europe's benefit C: aging problem in Germany is the worst in Europe D: Europeans have already made intelligent use of the land

She refused, so he turned away sadly and said he must do what he had made up his mind to do. At this word, the lady was greatly frightened for she was afraid for his life. So she called him back and gave him a dollar. The beggar took the money, put it into his pocket, and thanked her a great deal. "You have saved me from a terrible fate," he said. The lady asked him what he meant. The beggar replied, "Madame, I have been begging all day, but only you have taken pity on me. Without this dollar you gave to me, I should have had to go to work now. Question: If the woman had understood the beggar's words correctly, she would probably _ .

Read the article and select the best answer. Article: There are no exact differences between physics and other natural sciences because all sciences overlap .In general,however,physics is the scientific study of forces and qualities such as heat,light,sound,pressure,gravity and electricity,and the ways they affect other objects. One major branch of physics deals with the states of matter--solids,liquids and gases and with their motions.The pioneer achievements of Galileo,Kepler and Newton dealt with solid masses of matter in motion.Such studies deal with forces acting on moving objects.It is the subject of mechanics and belongs to the branch of mechanics called dynamics,the study of matter in motion.This large topic includes not only the motions of stars and ping-pong balls but also the motions of the water pumped by a fire engine and those of the air passing through the jet engine of an airplane. A branch of mechanics is statics ,the study of matter at rest.The designs of buildings and bridges are examples of problems in statics.Other branches of physics are based on the different kinds of energy,which interact with matter.They deal with electricity and magnetism ,heat,light,and sound.From these branches of physics scientists find clues which have revealed the constructions of atoms and how the atoms react to various kinds of energy. _ is often called the basis of modern physics.Among the many subdivisions of modern physics are electronics and nuclear physics.Physics is closely related to engineering.A person who uses knowledge of physics in solving everyday problems is often called an engineer.For example,electricity is one of the branches of physics;and an electrical engineer is a man who uses the "natural laws" of electricity to help in designing and electric generator . Question: Among many branches of modern physics is _ . Options: A: states B: electricity C: electronics D: mechanics
