单选题 Kuwait is a country which is quite small, but which is very rich. It has a population of a little more than a million and it is situated at the north end of the Persian Gulf, between Iraq on the north and Saudi Arabia on the south. This small desert country is one of the world's leading oil producers and it has about 15 percent of the world's known petroleum (石油) reserves. Since the discovery of oil in 1938, Kuwait rulers have turned the country into a prosperous(繁荣) welfare (福利) state. It has free primary and secondary education, free health care and social services, and the Kuwait do not have to pay any personal income tax for those services. The rate (比率) of literacy (识字,有文化) is high and constantly growing. The University of Kuwait was opened in 1966, but many of the Kuwait students still study in colleges and universities abroad, at state expense. Ku- wait is an Arab country, about 99 percent of the people who live there are Moslems. But fewer than half of these Moslems are actually citizen of Kuwait. This is because there are many Moslems immigrants living and working there. The other percent of the population, in other words the non-Moslems, are recent immigrants who were attracted by the opportunities to work for the oil companies. There are several thousand Europeans and Americans in Kuwait. Many of them are employed by the oil companies.
