4. critiquing all chemistry from Robert Boyle forward and also a vision of

给出的正确答案是B.解释说B is the best. 

B中的his的出现看起来就很舒服，严格意义上的特指。又是一个句末的同位语。

请牛人解释

提前谢谢

我觉得A中出现了介词since,就一定会有现在完成时与之搭配,A应该错在这里

不知道这个想法对不对,欢迎大家讨论

这题应该选A吧我个人认为 critique和vision并列 B里面his指代有问题 可以理解为是RB的吧

因为是同位语 名词性短语应该不牵扯到since+完成时的问题吧……个人意见
