PROBLEM: Article: You can have your adventure and eat too at Europe's first green restaurant where traditional German food is served in a beautifully lit wooden hilltop restaurant powered by solar energy at a height of 1,025 metres among tall trees in the Black Forest. The Rappenecker Hutte is a 350-year-old farm house in south Germany which has been serving as a hikers' restaurant for several years. It was the starting point of the downhill course of the Mountain Bike World Championship (MBWC) in 1995 and is a well-known station of the Black Forest Ultra Bike Marathon (BFUBM). "People come here for adventure trips, mountain biking or hiking and stop for traditional German food. We produce all our energy from renewable sources as it is very expensive to get a power grid connection at this site," said Dirk Behringer, owner of the Rappenecker Hutte. Like the restaurant, the story of its present owner is equally amazing as Behringer, 57, left his well-paid job in 2003 to stay here with his wife. "I have traveled across the world and as I was growing old I realized I wanted to retire and live in nature. So I rented the restaurant. Since then I, along with my wife, live here in summer and we travel during winter," said the six-foot-tall man dressed in a T-shirt and shorts. Due to heavy snow during winter, the restaurant opens only for six months from April to September when it receives around 500 guests per week. The Behringer couple has employed no helper and does everything from cooking to cleaning at this hilltop restaurant which gives a picturesque view of the Black Forest. There are not many dishes on the menu for unexpected visitors. On a routine basis, there is one vegetarian dish which includes fried potatoes with dense milk cream, boiled vegetables and fresh salad. The non-vegetarian dish includes fried potatoes with pork and salad. There are also options to pick from fresh juices, hard drinks and coffee. All vegetables, fruits, dairy products and meat supplies to the restaurant come from farms in nearby villages.
Question: By mentioning such events as MBWC and BFUBM, the author intends to _ .
Options: (A) prove the restaurant has a long history (B) advise us to do more exercise (C) stress the restaurant's being unusual (D) express his fondness of the restaurant

SOLUTION: C

PROBLEM: Article: The world's population is more mobile today than ever before. In 2010, more than 200 million people left their home countries to live in a new country. This is about 3 percent of the total world population. Some experts believe that number will swell to 400 million by 2050. Rates of immigration have remained strong for the last 300 years, but patterns of immigration have changed since World War II. The backgrounds and experiences of today's immigrants are different from those of the typical European immigrant of the nineteenth and early twentieth centuries. Contemporary immigrants range from unskilled laborers to highly skilled professionals, and they come from and go to countries all over the world. In the nineteenth century and until World War II, immigration was primarily in one direction- from the Old World to the New World. This is no longer the case. Countries such as Russia and China, which have long been, and continue to be, significant source countries, are now also destination countries. There is also considerable mobility inside regions, such as from one European country to another, or among the countries of the former Soviet Union. In spite of such differences, the push and pull factors for immigration remain essentially the same as they were 100 years ago. Most people move to another country because they want a better life. For the majority of immigrants, this means better economic conditions. As in past generations, a labor shortage in one country often draws workers from another country, especially if wages are significantly higher. In some small countries, for example, Qatar, United Arab Emirates, and Kuwait, there are more jobs than citizens. The demand for labor is so high that the majority of the population consists of foreign-born workers, ranging from highly skilled engineers and financial experts to domestic and construction workers. In traditional destination countries, such as the United States, however, labor needs have changed. Today, although there is still demand for unskilled labor, there is increasing demand for people with a high level of skill and education. The need for less skilled labor has shifted to other countries. As work on farms and in industry in the United States and Canada once drew workers from all over the world, now work in factories in Taiwan and south Korea attracts workers from Vietnam, the Philippines, and Cambodia. Most global immigration is legal: however, a large number of people also move across national borders illegally in pursuit of employment. Experts estimate that about 15 to 20 percent of immigrants worldwide are in their new countries illegally. The United States has the largest number of these immigrants, followed by South Africa, with significant numbers also in Northern and Western Europe and Mexico. These immigrants face particular challenges because they often must hide from the authorities who might deport them back to their home countries. Their illegal status also means that employers may take advantage of them by forcing them to work longer hours and paying them less than the legal minimum wage. Although economics remains the most important motivation in all forms of immigrant, other factors are also important. Some people decide to leave their home countries because their actions or political beliefs make it dangerous for them to remain. Others choose to leave because their home country has become too dangerous and unstable, often because of war or political unrest. They wish to find a place that is secure for themselves and their families. Education is also a significant factor for many modern immigrants. They want to raise their children in a place where they can get a good education, which, in turn, they hope will provide them with better prospects for the future. Finally, family and community ties also play a role in immigration decisions. As in the past, once a group of people from one country establishes a community in a new country, more people from that country is likely to follow. The pattern, direction, and rate of immigration may change as the global economy changes. However, as long as life in a new country is more attractive than life in the old country, immigration will continue.
Question: According to the reading, what are the patterns of immigration in China and Russia today?
Options: (A) Many people leave these countries while many people also immigrate to them. (B) They are major source countries for immigration. (C) They are major destination countries for immigrants. (D) Some people immigrate to these countries but many more people leave them.

SOLUTION: A

PROBLEM: Article: About five states in Nigeria will experience a total eclipse of the sun on March 29, 2006, according to a forecast by the Ministry of Science and Technology this week. An eclipse occurs in one of two ways: when the moon passes between the earth and the sun so that all or part of the sun cannot be seen for a time, or when the earth passes between the moon and the sun so that you cannot see all or part of the moon for a time. The first case is a solar eclipse or eclipse of the sun, which occurs as the earth enters the shadow of the moon. The second describes a lunar eclipse or eclipse of the moon, which happens when the moon enters the shadow of the earth. More than 60 percent of Nigerians are uneducated, and eclipses in some parts of the country in the past have caused commotions in which people have been killed and property destroyed. Some Nigerians believe an eclipse is punishment from the gods for evil doing. The March 29th eclipse would be the fifth in prefix = st1 /Nigeria's history, and it is expected to last for 30 minutes -- 9:15AM to 9:45AM, according to the official prediction.Nigeriawitnessed eclipses in 1898, 1947, 1959, and 2001. The shadows in an eclipse have a central dark part called umbra, and a less dark external section called penumbra. In the umbra, all the sun's light is cut off, and this is called total eclipse; while in the penumbra, only a part of the light from the sun is cut off from the moon, and it is called partial eclipse. Five Nigerian states -- Oyo, Kwara,Niger, Zamfara, and Katsina -- are expected to have total eclipse, while other parts of the country will experience partial eclipse.
Question: This passage is mainly written to _ .
Options: (A) predict a eclipse of the sun in Nigeria (B) compare a eclipse of the sun with a eclipse of the moon (C) provide information on a coming eclipse of the sun in Nigeria (D) show that people in Nigeriareceive little education
