问题    A new report of the United Nations shows that, if the present growth rate of 2 percent per year continues, today’s world population of 5.1 billion will hit 6.4 billion by the year 2000.
   What’s more, the great part of the growth—9 of every 10 people added to the earth’s population—will be in the poor and undeveloped countries. These are the nations where providing enough food for billions of people already is proving to be a headache problem.
   By the year 2000, today’s "have not" nations will have a total population of 5 billion people, nearly four fifths of the world’s population.
   Food isn’t the only problem that such a population explosion presents. The more people there are and the worse their living conditions, the greater grow the possibility of all kinds of social problems.
   In 1830, world population reached 1 billion. It took only 100 more years to add another billion to world population; just 30 more to add a third billion. And it took just 15 more years to reach the 4 billion mark in 1975.
   Actually, the world’s birth rate is falling. But so is death rate, as medical advances have made it possible for man to live longer than before. Such advances have also reduced baby death rate. Unless population growth is reduced, the world population may reach 12 billion in a century. Is the earth capable of providing a good life for so large a population?
选项 A、a lot of social problems
B、medical advances
C、a decrease in food production
D、a worse life in every nation with 3 billion
答案 A
解析 本题为细节题，信息点定位在第四段第二句“The more people there are and the worse their living conditions，the greater grow the possibility of all kinds of social problems．”。本题干为人口爆炸产生的结果，而B项为其产生的原因，因果倒置，因此排除；文中确实讲到人口增长会引起食物相对短缺，但C项语气过于绝对，也排除；D项内容没有提及，因此选A。
