I'm taking a test and have to guess the right answer to the question after the article. Article: Scientists say they have discovered a promising treatment for sleeping sickness, a killer disease that infects about 60,000 people in Africa a year. British and Canadian experts say drugs could attack the parasite causing the illness needs to survive. They say the drug could be ready for human medical test in about 18 months. The disease, spread by the bite of a fly, is caused by a parasite attacking the central nervous system. It has similar symptoms to malaria , making it difficult to diagnose. Left untreated, it moves to the brain, resulting in mental confusion and final death The "breakthrough" came at the University of Dundee in Scotland, where scientists were offered money to research diseases ignored by major drugs companies. Professor Paul Wyatt, director of the programme, said: "This is one of the most significant findings made in recent years in terms of drug discovery and development for ignored diseases." He said the research, published in the journal Nature, represented "significant progress" in the development of a full blown drug against the disease. The World Health Organization said there are between 50,000 and 70,000 cases of the disease a year, with a further 60 million people at risk of infection. The research in Dundee was _ by partners at the University of York in England and the Structural Genomics Consortium in Toronto, Canada. The two drugs currently available to treat sleeping sickness both have problems. One is with side effects that kill one in 20 patients and the other is costly, only partially effective and requires long-time hospital treatment, the scientists said. Question: We can learn from the passage that _ . Options: A: big drug companies play an important role in the research of the new drug B: people who get infected with the disease are mentally disturbed C: among 200 people infected with the disease, 5 may die because of the old drug D: Professor Paul Wyatt may be a professor at the University of York

I'm taking a test and have to guess the right answer to the question after the article. Article: The blues was born on the Mississippi River Delta in the early 1900s. After the Civil War, the slaves were free but life was still not easy. They had to find new work. In the south, work camps were formed. Black people from these camps worked on farms and built up the Mississippi River banks. During the week, the people worked long and hard. They often lived alone, without their families, far from home. On the weekends, the workers got together at picnics or drinking places. Traveling black musicians with guitars entertained them. The musicians sang songs about the difficult life of the workers. These songs were called the blues. If you have the blues, it means you feel very sad. But blues songs were not always sad. Some of them were happy and many of them were funny. Early blues singers often had very interesting names like Blind Lemon Jefferson and Howlin Wolf. Sometimes, the blues singers had song contests. Each singer sang new words or a new style of the blues song. They made up the music as they played. In this way they created new music. This is called improvisation. Later, improvisation became a very important part of Jazz music. The blues began in the country in the south. As blacks moved into the big cities to work, the blues went with them. There, they sang about life in the cities. W. C. Handy, a black band leader from Memphis made the blues popular all over America. In 1914 he wrote the most famous song of all "The St. Louis blues." Question: The blues songs used to tell about . Options: A: the funny life of singers B: the happy life of black musicians C: the lonely life of black people D: the hard life of black people

I'm taking a test and have to guess the right answer to the question after the article. Article: When the Spanish first brought chocolate back to Europe,it was still being served as a drink,but soon went through an important change:the chili pepper was replaced by sugar. The new sweetened chocolate drink was so expensive that few could afford,but by the 17th century the drink was common among European noblemen. In England,which was somewhat more equalityfavored than the rest of Europe,chocolate was more widely available. Those who could afford it could enjoy chocolate drinks in the new coffee and chocolate houses of London. As cacao tree became more commonly available,people began experimenting with new ways of using it. Chocolate began to appear in cakes and other foods. But it wasn't until 1828 that the "modern ear" of chocolate making and production began. The introduction of cocoa powder not only made creating chocolate drinks much easier,but also made it possible to combine chocolate with sugar and then remix it with cocoa butter to create a solid. Others began to build on Van Houten's success,experimenting to make new chocolate products. In 1849,English chocolate maker Joseph Storrs Fry produced what was the world's first eating chocolate. Today,the Swiss are famous for their chocolate,and rightly so. In the late 19th century,they developed a number of processes that contributed greatly to creating the solid chocolate candy that we all enjoy today. Two major developments occurred in 1879.First,Daniel Peter,a Swiss chocolate producer,had the idea of using powdered milk (invented by Swiss Chemist Henri Nestle in 1867) to make a new kind of chocolate,milk chocolate. Second,Rudolph Lindt invented a process called "conching",which greatly improved the quality of chocolate candy by making it more mixable. Question: The passage mainly discusses the development of _ . Options: A: cacao B: chocolate drinks C: chocolate candies D: chocolate houses

Article: There are stories about two U.S . presidents,Andrew Jackson and Martin Van Buren,which attempt to explain the American English term OK.We don't know if either story is true,but they are both interesting. The first explanation is based on the fact that President Jackson had very little education.In fact,he had difficulty reading and writing.When important papers came to Jackson,he tried to read them and then had his assistants explain what they said.If he approved of a paper, he would write "all correct"on it.The problem was that he didn't know how to spell.So what he really wrote was "ol korekt".After a while,he shortened that term to "OK". The second explanation is based on the place where President Van Buren was born,Kinderhook,New York.Van Buren's friends organized a club to help him become President .They called the club the Old Kinderhook Club,and anyone who supported Van Buren was called"OK".
