One of the questions that is coming into focus as we face growing scarcity of resources of many kinds in the world is how to divide limited resources among countries. In the international development community, the conventional wisdom has been that, the 2 billion people living in poor countries could never expect to reach the standard of living that most of us in North America enjoy, simply because the world does not contain enough iron ore. protein, petroleum, and so on. At the same time, we in the United States have continued to pursue super affluence as though there were no limit, s on how much we could consume. We make up 6 percent of the world''s people; yet we consume one-third of the world''s resources.
As long as the resources we consumed each year came primarily from within our own boundaries, this was largely an internal matter. But as our resources come more and more from the outside world, "outsiders" are going to have some stay over the rate at which and terms under which we consume. We will no longer be able to think in terms of "our" resources and "their" resources, but only of common resources.
As Americans consuming such a disproportionate share of the world''s resources, we have to question whether or not we can continue our pursuit of super affluence in a world of scarcity. We are now reaching the point where we must carefully examine the presumed link between our level of well-being and the level of material goods consumed. If you have only one crust of bread, then an additional crust of bread doesn''t make that much different. In the eyes of most of the world today, Americans have their loaf of bread and are asking for still more. People elsewhere are beginning to ask why. This is the question we''re going to have to answer, whether we''re trying to persuade countries to step up their exports of oil to us or trying to convince them that we ought to be permitted to maintain our share of the world fish catch.
The prospect of a scarcity of, and competition for, the world''s resources requires that we reexamine the way in which we relate to the rest of the world. It means we find ways of cutting back on resource consumption that is dependent on the resources and cooperation of other countries, We cannot expect people in these countries to concern themselves with our worsening energy and food shortages unless we demonstrate some concern for the hunger, illiteracy and disease that are diminishing life for them.

单选题
What is the conclusion of this passage?
【正确答案】
C
【答案解析】主旨概括题。文章的结论在末段，尤其是最后一句指出：“我们只有关心其他不发达国家人民生活中的饥饿、无知和疾病问题，才能指望他们关心我国的能源匮乏和食物短缺问题”。C项中“care about the well-being(福利)of other countries”符合此意，故为正确答案。A、B两项都未在文中提到。D项内容则超出了此文结论中的要求，并没要求美国人“find ways of cutting back on resource consumption”(找到削减资源消耗的办法)以及“demonstrate some concern for...”(对…表示某种关心)，故不宜选用。
