问题     A simple idea supports science: "trust, but verify". Results should always be【C1】________to challenge from experiment. That simple but powerful idea has【C2】________a vast body of knowledge.【C3】________its birth in the 17th century, modern science has changed the world【C4】________recognition, and overvehemently for the better.
    But success can【C5】________self-contentment. Modern scientists are doing too much trusting and not enough verifying, which does harm to both the whole of science and humanity.
    Too many of the【C6】________that fill the academic field are the result of inferior experiments or poor analysis. A rule of thumb among biotechnology venture-capitalists is that half of【C7】________research cannot be reproduced. Even that may be【C8】________. Last year researchers at one biotech firm, Amgen, found they could reproduce just six of 53 "landmark" studies in cancer research. Earlier, a group at Bayer, a drug company,【C9】________to repeat just a quarter of 67 similarly important papers. A leading computer scientist complains that three-quarters of papers in his subfield are nonsense.
    The reasons might lie in this: researchers are no longer willing to verify hypothesis investigated by other scholars since these papers have rare chance to be published. All this makes a poor foundation for an enterprise dedicated【C10】________discovering the truth about the world. What might be done to shore it up? One【C11】________should be for all disciplines to follow the example of those that have done most to tighten standards.
    【C12】________research protocols should be registered in advance and monitored in virtual notebooks. This would【C13】________the temptation to distort the experiment’s design so as to make the results look more【C14】________than they are.【C15】________possible, trial data also should be open for other researchers to【C16】________and test.
    Science still【C17】________enormous respect. But its privileged【C18】________is founded on the capacity to be right most of the time and to correct its mistakes when it gets things wrong. And it is not as if the universe is short of【C19】________mysteries to keep generations of scientists nard【C20】________. The false trails laid down by inferior research are an unforgivable barrier to understanding.
【C13】
选项 A、curb
B、snap
C、arouse
D、discard
答案A
解析 从空格后的定语to distort the experiment’s design.(扭曲实验设计)可知，这是不好的方面。上文提到要tighten standards(严格标准)，因此扭曲实验设计应该是不被允许的行为，故选A项curb“抑制”。B项snap“折断”和D项discard“抛弃”为具体动作，不与temptation搭配。C项arouse“引起”代入句子，不符合句意。
