Question

The science of medicine,＿progress has been very rapid lately,is perhaps the most important of all the science.A to which B in which C which D with which 选哪个?为什么?一定要有解释啊,而且我觉得那个rapid是不是该为rapidly?

Answer 1

B,make progress in sth.,在某方面取得进步
rapid 不能换成rapidly,-ly是副词,应该修饰动词,而在这里,rapid修饰的是名词progress
