问题     American’s genius with high technology may have put men on the moon, but there is growing skepticism about its ability to solve human problems closer to home.
    In fact, a subtle but significant shift from purely technological solutions is already under way as scientists argue openly for new directions in research.
    A growing number of scientists insist that answers to the world’s problems will not come from a flashier array of electronics and machines. Instead, as they see it, solutions must evolve from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential of the earth’s resources.
    What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economies and even philosophy.
    More and more of the best minds in science, particularly young researchers, are being &awn    into these developing fields.
    All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems.
    Where the real challenge lies, in the view of the new breed of scientists, is in finding ways to produce goods to meet the world’s needs, using less of the raw materials that are becoming scarce. [br] In the passage "human problems" or "world problems" refers mainly to ______.
选项 A、global food shortage
B、resources depletion
C、environmental pollution
D、all of the above
答案 D
解析 综合判断题。第六段中“energy and food shortage”和“environment difficulties”均有所提及，故A、B、C三项皆属正确。
