Tough SC..

More than thirty years ago Dr. Barbara McClintock, the Nobel Prize winner, reported that genes can "jump," as pearls moving mysteriously from one necklace to another.
1.as pearls moving mysteriously from one necklace to another
2.like pearls moving mysteriously from one necklace to another
3.as pearls do that move mysteriously from one necklace to others
4.like pearls do that move mysteriously from one necklace to others
5.as do pearls that move mysteriously from one necklace to some other one
OA:2
My Problem with this question:Other than eliminating 3(for using like pearls do) and 5(for the awkward usage to some other one), how do I eliminate the other 2 choices.
In fact, I am not finding anything wrong with this construction originally. :(

In A, as is used to compare a clause (genes can jump) to a phrase (pearls moving from one necklace to another).
Generally, as should be used to compare one CLAUSE to another CLAUSE.
Eliminate A.

In D, like cannot be used to compare actions (genes can JUMP like pearls DO). Like is used to compare NOUNS; as is used to compare ACTIONS.
Eliminate D.

C and E imply that, just as genes JUMP, so DO pearls.
Not the intended meaning: pearls do not JUMP.
Eliminate C and E.

The correct answwer is B.

Note that in the OA (as well as in answer choice A), moving is an adjective modifying pearls.
What KIND of pearls?
Pearls MOVING FROM ONE NECKLACE TO ANOTHER.

Thus, the OA compares NOUNS, not actions: GENES can jump, like PEARLS moving mysteriously from one necklace to another.
GENES are like PEARLS.
