单选题 According to the author, we should reverse our classification of the physical sciences as "hard" and the social sciences as "soft" because ______.

A、 a reverse ordering will help promote the development of the physical sciences
B、 our knowledge of physical systems is more reliable than that of social systems
C、 our understanding of the social systems is approximately correct
D、 we are better able to investigate social phenomena than physical phenomena

【正确答案】 C

【答案解析】[试题分析] 本题为作者观点题。
[详细解答] A、B两项与作者的观点不符，首先应当排除。D项指“相对于自然科学来说，我们在社会科学方面的研究能力更强。”文中并未指出这一点。可从文中Our knowledge of social systems．．．is not likely to be seriously overturned by new discoveries．找到C项的出处。
