问题     But the success of science, both its intellectual excitement and its practical application, depends upon the self-correcting character of science. There must be a way of testing any valid idea. It must be possible to reproduce any valid experiment. The characters or beliefs of scientists are irrelevant; all that matters is whether the evidence supports their contention. Arguments from authority simply do not count; too many authorities have been mistaken too often. I would like to see these very effective scientific modes of thought communicated by the schools and media; and it would certainly be astonishment and delight to see them introduced into politics. Scientists have been known to change their minds completely and publicly when presented with new evidence or new arguments. I cannot recall the last time a politician displayed a similar openness and willingness to change.
The passage mainly discusses______.
选项 A、some similarities between politicians and scientists
B、an important characteristic of science
C、practical applications of science
D、the rewards of a valid experiment
答案B
解析 这是一道主旨题，考查的是考生的概括总结能力。文章开篇第一句就说明科学的成功在于其自我更正的特性，任何正确的观点都经得起试验论证。接下来，文章说明证据是科学研究中至关重要的内容，而权威人士也会经常犯错误。最后，文章阐述了科学家在新的事实和证据出现时会公开修正自己的观点，而这种自我更正的特点也正是科学家和政客之间的区别。综上所述，文章主要讲述的是科学自我更正这个重要特征，因此选B。
