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 overwhelmingly 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 hard【C20】________. The false trails laid down by inferior research are an unforgivable barrier to understanding.
【C9】
选项 A、afforded
B、succeeded
C、managed
D、failed
答案C
解析 根据空格后的已知信息“仅仅能复制67篇重要论文其中的四分之一”及前一句“只能复制六篇‘里程碑式’的论文”，可以确定要完成这些实验的复制非常困难。故应选C项manage “(通过努力)勉强完成”。A项afforded“承担得起”，本文并不是讨论研究费用问题，故此选项无根据。B项succeeded“成功做某事”，后面应接介词in，用作succeed in doing sth.。D项failed to do sth. 表示做某事失败了，跟原意相反。
