Hey Guys,
All the correct explanations have been given here, but there is also some misinformation, so I thought I'd finish it off for you. Also, please try to post questions with full grammatical correctness (i.e. please read over what you wrote and edit it if there are errors). Also, it really helps people out if you place the underline using the tools up above the input box. Thanks!
More than 30 years ago Dr. Barbara McClintock, the Nobel Prize winner, reported that genes can "jump", as pearls moving mysteriously from one necklace to another.
(A) as pearls moving mysteriously from one necklace to another
(B) like pearls moving myteriously from one necklace to another
(C) as pearls do that move mysteriously from one necklace to others
(D) like pearls do that move mysteriously from one necklace to others
(E) as do pearls that move mysteriously from one necklace to some other one
(A) "as" requires a clause after it. A clause requires a verb, but we don't have one here. "moving" is a participle (i.e. a type of adjective).
(B) CORRECT!
(C) This answer choice
does use "as" correctly. Unfortunately, the word "that" is a relative pronoun, and it modifies whatever it touches. In this case, it's touching a verb ("do"), which it cannot modify. "One necklace to others" is slightly weird; a single pearl can't move to multiple necklaces at once.
(D) "like" cannot have a clause after it. The word "do" signals this as a clause, so the "like" is wrong.
(E) This answer choice
does use "as" correctly. However, it makes a meaning error. This implies that pearls
actually move from one necklace to another, which they don't. Also, "one necklace to some other one" is awkward.
Hope that helps/puts this to bed!
