Write the correct letter A, B, C or D in boxes 37-40 on your answer sheet.
a tendency for negative results in early trials

选项 A、 
B、 
C、 
D、 

答案A

解析 由negative results in early trials可定位至E段倒数第三句,该处指出,早期实验很少有积极的结果,故社会科学家对对照实验的方法失去了兴趣。其中题目early trials与early experiments为同义表达,a tendency for negative results的表述与produced little evidence of positive outcomes相符,故答案为A。
