答案是A。原因是文章提到,虽然经济学家认为高水平的国民储蓄率会导致低实际利率和高度投资,但上世纪60年代美国却出现了背反这一观点的情况,以及1980年到1982年期间,尽管国民储蓄和投资量大致相等,但实际利率却突然飙升,这都证明经济学家的观点是被违反的,所以A选项是正确的。
在A和C中纠结,错选了C
C:他们错误地识别了除储蓄和投资利率以外影响实际利率的其他因素。实际上,他们不是错误识别,而是根本没识别啊
考察了作者的态度:作者并没有反驳经济学家,而是在其基础上增加了一些其他的解释, 和这个态度不一致的选项可以排除
B-关于外国和本国商品价格涨跌是作者提出修正和进一步解释真实利率、存款率和商业投资关系的论据,和经济学家本来的argument无关
C-经济学家没有identify其他因素,作者填补了其他因素
d-不是经济学家的argument
E-这里和作者态度不符
however前没有否定经济学家,只是描述其观点。
比较ab,选a
