People are,on the whole,poor at considering background information when making individual decisions.At 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 probation 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.He studied the results of 9,323 MBA interviews,12 by 31 admissions officers.The interviewers had 13 applicants on a scale of one to five.This scale 14 numerous factors into consideration.The scores were 15 used in conjunction with an applicant's score on the Graduate Management Admission Test,or GMAT,a standardised exam which is 16 out of 800 points,to make a decision on whether to accept him or her.Dr Simonsohn found if the score of the previous candidate in a daily series of interviewees was 0.75 points or more higher than that of the one 17 that,then the score for the next applicant would 18 by an average of 0.075 points.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.
上下文语义衔接+形容词辨析该题难度较大，需把句意弄懂，也就是“这30分是比……所多的”建议把四个选项分别代入空格处，A“必须的”，B“可能的”，C“有前途的”，D“有帮助的”，对比之后，只有A最合逻辑，也就是说“这30分是比原本该考试所必须要求的多出来的，即另外多拿本不需要的30分才能平衡前面的更低的分数”，故A为正确选项。
