Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 31 to 35

The relationship between Britain and the US has always been a close one. Like all close relationships it has had difficult times. The US was first a British colony, but between 1775 and 1783 the US fought a war to become independent. The US fought the British again in the War of 1812.

In general, however, the two countries have felt closer to each other than to any other country, and their foreign policies have shown this. During World War I and World War II, Britain and the US supported each other. When the US looks for foreign support, Britain is usually the first country to come forward and it is sometimes called “the 51^st state of the union”.

But the special relationship that developed after 1945 is not explained only by shared political interests. An important reason for the friendship is that the people of the two countries are very similar. They share the same language and enjoy each other's literature, films and television. Many Americans have British ancestors, or relatives still living in Britain. The US government and political system is based on Britain's, and there are many Anglo-American businesses operating on both sides of the Atlantic. In Britain some people are worried about the extent of US influence, and there is some jealousy of its current power. The special relationship was strong in the early 1980s when Margaret Thatcher was Prime Minister in Britain and Ronald Reagan was President of the US.
