略
选项分析:
A选项:Correct. 本选项在语法和逻辑上均是正确的。
B选项:代词it的指代对象有误。it是实物代词,指代语境中出现过的单数名词。这里只能指代the male size increase。在逻辑上,男性型号的增加不会在女性中变大,所以has been great的逻辑主语论元应为the size increase in females。
C选项:had been slight时态有误。because前半句用了现在完成时,而后半句应该是和前半句几乎同时发生的,所以理应也用现在完成时。
D选项:划线部分引导的原因状语because of the size increase being slight for males for females it was great的核心词为size increase。但在逻辑上,The typical size difference between males and females has lessened since the origins of the human species的原因是“男性型号增长小而女性型号增长大”这件事,而不是“男性型号”本身。
E选项:核心词错误同选项(D)。
