More than 30 years ago Dr.Barbara Mc, the Nobel Prize winner, reported that genes can "jump," (as pearls moving mysteriously from one necklace to another.)

b) like pearls moving mysteriously from one necklace to another
c) as pearls do that move mysteriously from one necklace to others

正确答案b没有问题，但是og后面对c的解释有点看不懂：
Mc's smile creates an image that is not real; the use of the verb "do" indicates the pearls' movement as a reality

请问这是什么意思？是不是除了as和like的考点，还有什么我不理解的东西在里面？
