问题 The title below that best expresses the ideas of this passage is ______.
Basic research is vital because ______.
选项 A、it leads to results that can be appreciated
B、it is driven out by applied research
C、it provides the basis for scientific progress
D、its results cannot be anticipated
答案C
解析 事实细节题。第一段第二句“Basic research is the very heart of science...a capital that must be constantly increased as the demands upon it rise．”由此可知，基础研究为科学发展提供了动力，为科学进步提供了基础，就像一家企业如果拥有雄厚的资金，必然会迅速地发展一样。所以C项正确。A.与第一段最后相悖．即基础研究的实际应用常常无法预期；而D.虽然符合文意，却不足基础研究极端重要的原因;B.见上题对D项的分析。
