问题     The U. S. Bureau has estimated that the population of the United States could approach 300 million in 2000 and will be 400 million in 2020. And the U.S. Department of Commerce estimates that the average U.S. per capita income will increase from $3,400 in 1969 to the equivalent of $8,300 (assuming a 1967 price level) in the year 2000, 2.5 times as much as that of 1969.
    According to government statistics, in the United States, there are over 110 million cars and "more people" means "more cars". By the end of twenties of next century, the population of the United States will have doubled that of today and the number of automobiles will be doubled as well. And in twenty-year’s time the per capita income will also be 2.5 times higher than it is. If this increase income is spent on more and larger automobiles, larger houses, and increased consumption of other material goods, the results could cause catastrophic resource exhaustion, and pollution. Take the increase of the consumption of oil for instance. The consumption is so huge that the reserves might last only a decade or two if not supplemented by imports.
    Ten years ago it appeared that nuclear power would solve the anticipated energy crisis. Although supplies of uranium fuel were known to be limited and might become exhausted in half a century, the nuclear power plant has for a long time been a favorite project. But work on it has met with grave problems. The fear of possible atomic explosion and the problem of disposing of polluting by-product waste have slowed down the construction of further nuclear plants. Eventually atomic technology may be able to control these problems, but at present there seems to be little agreement among atomic scientists about when this can be achieved.
选项 A、The population will increase, but the income will decrease.
B、The population will decrease, but the income will increase.
C、Both will increase.
D、Both will decrease.
答案C
解析 根据文章第一段，调查结果表明美国的人口将从2000年的3亿上升到2020年的4亿，人均收入将同时一起增长，因此，答案选项正确。
