问题 Which of the following titles best summarises the main idea of the passage?
According to the passage, less developed countries ______.

选项 A、Spend little on research
B、realize that progress depends on basic research
C、encourage their career scientists to experiment
D、devote less than 7% of their scientific budget to basic research

答案D

解析文章第二段第二句提到For practical reasons, the sums spent on applied research in any country...and the proportions are more unequal in the less developed countries。由此可知，不发达国家基础研究的资金比例肯定小于发达国家。本段第三句后半部分提到the funds the U.S. Government allots to basic research currently amount to about 7 percent of its overall research and development funds，即美国拨给基础研究的基金大约占其全部研究和发展基金的7%，那么不发达国家的基础研究基金肯定要小于7%，故选D。虽然不发达国家用于基础研究与应用研究的资金比例比发达国家更加不平衡，但是我们不能因此推断不发达国家用于研究的资金很少，故排除A，分析文中的事实可知不发达国家并未认识到基础研究的重要性，故排除B；C项在文中未提及。
