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 character or beliefs of scientists are irrelevant; all that matters is whether the evidence supports their contentions(观点). 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 the media(传播媒介); and it would certainly be an 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 argument. I cannot recall the last time a politician displayed a similar openness and willingness to change.
According to the passage, if a scientist repeats an experiment several times and does not produce similar results each time, the experiment must be______.
选项 A、extremely complex
B、scientific
C、incorrectly recorded
D、invalid
答案D
解析
