Clauses have subjects and verbs and are introduced by conjunctions or relative pronouns; phrases do not have subjects and verbs and are frequently introduced by prepositions. The preposition like, not the conjunction as, should introduce the underlined phrase.
AAs incorrectly introduces a phrase when like is required
BCorrect. In this sentence, the preposition like properly introduces the phrase.
CMcClintock's simile creates an image that is not real; the use of the verb do indicates the pearls' movement as a reality
DLike incorrectly introduces a clause; the verb do indicates a reality instead of an image that is only imagined
EPearls do not actually move; McClintock is suggesting an image only. Some other one is a wordy replacement for another
答案是B , 但是我不太明白ETS的解释,为什么不能用AS , 是说 这只是个比喻而不是真的,所以只能用like , 不能用as 嘛? 如果这样用as 可以嘛? as pealrs move mysteriously from one necklace to another

So i think actually if the answer is 'as perls movemysteriously from one necklace to others' is also acceptable.
but answer C use ' as pearls do that move mysteriously from one necklace to others', and 'do that move' means the acually pearls 'moves'.
According to the main sentence, 'genes can jump' and 'pearls move' is just a imagination and a simile, thus it is not suitable to use ' do the move' to indicate the move of the pearl.
