People are, on the whole, poor at considering background information when making individual decisions.A.t first glance this might seem like a strength that 1 the ability to make judgments which are unbiased by 2 factors. But Dr Uri Simonsohn speculated that an inability to consider the big 3 was leading decision-makers to be biased by the daily samples of information they were working with. 4 , he theorised that a judge 5 of appearing too soft 6 crime might be more likely to send someone to prison 7 he had already sentenced five or six other defendants only to forced community service on that day.
To 8 this idea, he turned to the university-admissions process. In theory, the 9 of an applicant should not depend on the few others 10 randomly for interview during the same day, but Dr Simonsohn suspected the truth was 11 .

This might sound small, but to 19 the effects of such a decrease a candidate would need 30 more GMAT points than would otherwise have been 20 .

本题测试考生根据上下文确定逻辑关系和词义的能力。前文已经证明了这种分数“波动”情况的存在。本句讲述的是作者认为这种“波动”带来的不利影响。本句相关的内容是“一个GMAT考生需要额外的30分才能…这种(分数)降低带来的后果”。根据前文内容，“波动”会造成分数的不准确，即有些考生的分数被压低。因此，只有undo（抵消，废除，取消）符合上下文的逻辑关系。achieve“获得，赢得”和maintain“保持，维持”方向上正好相反。disregard“忽略，不考虑”虽然词义上是否定的，但“忽略，不考虑”从逻辑关系上与上下文不符。
