[单项选择]Passage One
The term profit in economics has a very precise meaning. Economists, however, often loosely refer to "good deals" or profitable ventures with no risk as profit opportunities. The general view of economics is that profit opportunities are rare. At any one time there are many people searching for such opportunities, and as a consequence few exist.
At major banks in big cities, you can buy foreign currencies. The prices of these currencies are determined in world markets. With dollars we can buy marks, with these marks we can buy francs, and with these francs we can buy back dollars. If, for example, the dollar-franc price is too low with respect to the other prices, there is an immediate rush to buy dollars and sell francs, not by ordinary citizens at bank windows, but by a few large currency traders in Tokyo or New York who watch prices every minute. Such a rush drives up the dollar-franc price to the no-profit-opportunity point. There are in fact

Oil Industry in Norway
The Norwegian Government is doing its best to keep the oil industry under control.A new law limits exploration to an area south of the southern end of the long coastline;production limits have been laid down(though these have already been raised);and oil companies have not been allowed to employ more than a limited number of foreign workers.But the oil industry has a way of getting over such problems,and few people believe that the Government will be able to hold things back for long.
As an Norwegian politician said last week:"We will soon be changed beyond all recognition."
Ever since the war,the Government has been carrying out a program of development in the area north of the Arctic Circle.During the past few years this program has had a great deal of success: Tromso has been built up into a local capital with a university,a large hospital and a healthy industry.But the oil industry has already started to draw people south,and within a few years the whole northern policy could be in ruins.
The effects of the oil industry would not be limited to the north,however. With nearly 100 percent employment,everyone can see a situation developing in which the service industries and the tourist industry will lose more of their workers to the oil industry.Some smaller industries might even disappear altogether when it becomes cheaper to buy goods from abroad.
The real argument over oil is its threat to the Norwegian way of life.Farmers and fishermen do not make up most of the population,but they are an important part of it,because Norwegians see in them many of the qualities that they regard with pride as essentially Norwegian.And it is the farmers and the fishermen who are most critical of the oil industry because of the damage that it might cause to the countryside and to the sea.
In the south,one effect to the development of the oil industry might be________.
A.a large reduction on unemployment
B.a growth in the tourist industry
C.a reduction in the number of existing industries
D.the development of a number of service industries
