Article: The United States of America is the most culturally diverse country in the world in terms of culture religion, ethnicity and sexual orientation. As a combination of various races and cultures, America is home to all. The culture here is so unique that citizens can be just as proud of their original cultural heritage as they are to be American. What is now the US was initially inhabited by native people until the land was settled by various European groups and African slaves. Since the 20th century, the country has become a heaven for people from all over the globe . The arrival of immigrants has shifted populations from rural areas into cities because immigrants tend to settle in urban areas. At present, 81 percent of the inhabitants in the US live in cities. Cultural and ethnic diversity adds a unique flavor to cities that is expressed through distinct neighborhoods, restaurants, places of worship, museums, nightlife and multicultural learning environments. Unique musical forms, such as jazz, rock and roll, Chicano music, and the blues, grow in the US by mixing a variety of culturally distinct musical traditions to create a new form. At the executive level, the country is headed by a mixedrace president; two posts on the Supreme Court are held by members of the country's two largest minorities.There is also diversity in state and local governments. Without its rich mixture of races and cultures, America would not be the nation that it is today. Founded upon the basis of equality and freedom, America acts as a stage where different cultures not only coexist peacefully, but develop well.

Asnwer: A
Yes

Article: Money spent on advertising is money spent as well as any I know of. It selves directly to bring about a rapid sale of goods at reasonable prices, so setting up a firm home market and so making it possible to provide for export at good prices. By drawing attention to new ideas it helps greatly to raise standards of living. By helping to increase demand it causes an increased need for labor, and is therefore a nice way to fight unemployment. It lowers the costs of many services: without advertisements your daily newspaper would cost four times as much, the price of your television program would need to be doubled, and travel by bus or subway would cost more. And perhaps most important of all, advertising provides a promise of reasonable value in the products and services you buy. Besides the fact that twenty-seven Acts of Parliament govern the terms of advertising, no regular advertiser dare promote a product that fails to live up to the promise of his advertisements. He might fool some people for a little while through misleading advertising. He will not do so for long, for the public has the good sense not to buy the poor article more than once. If you see an article frequently advertised, it is the proof I know that the article does what is promised for it, and that it has good value. Advertising does more for the good of the public than any other force I can think of. There is one more point I feel I ought to touch on. Recently I heard a well-known television person declare that he was against advertising because it persuades rather than informs. He was telling us the real difference. Of course advertising tries to persuade. If its message were nothing but information, that would be difficult to get more people to buy, for even a detail such as the choice of the color of a shirt is a bit persuasive-advertising would be so boring that no one would pay any attention. But perhaps that is what the well-known television person wants.
Question: By the first sentence of the passage the writer means that _ .
Options: (A) he is fairly familiar with the cost of advertising (B) everybody knows well that advertising is a waste of money (C) advertising costs more money than everything else (D) money spent on advertising is worth while
Asnwer: C
No

Article: Ever since they were first put on the market in the early 1990s, genetically modified (GM, ) foods have been increasingly developed and marketed in many countries in the world, mainly on the basis of their promise to end the worldwide food crisis. But can GM technology solve world hunger problems? Even if it would, is it the best solution? Despite what it promises, GM technology actually has not increased the production potential of any crop. In fact, studies show that the most widely grown GM crop, GM soybeans, has suffered reduced productivity. For instance, a report that analysed nearly two decades of research on major GM food crops shows that GM engineering has failed to significantly increase US crop production. Something else, however, has been on the rise, While GM seeds are expensive, GM companies tell farmers that they will make good profits by saving money on pesticides . On the contrary, US government data show that GM crops in the US have produced an overall increase in pesticide use compared to traditional crops. "The promise was that you could use less chemicals and _ production. But neither is true," said Bill Christison, President of the US National Farm Coalition. At the same time, the authors of the book World Hunger: Twelve Myths argue that there actually is more than enough food in the world and that the hunger crisis is not caused by production, but by problems in food distribution and politics. These indeed deserve our efforts and money. Meanwhile, the rise in food prices results from the increased use of crops for fuel rather than food, according to a 2008 World Bank report. As a matter of fact, scientists see better ways to feed the world. Another World Bank report concluded that GM crops have little to offer to the challenges of worldwide poverty and hunger, because better ways out are available, among which "green" farming is supposed to be the first choice.
Question: GM companies promise farmers that they will benefit from _ .
Options: (A) practicing "green" farming (B) use of less chemicals (C) fair distribution of their crops (D) using more crops for fuel
Asnwer: C
No
