OG 10 SC

by prachi18oct » Thu Aug 28, 2014 11:34 pm
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.
(A) 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
(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

I chose E as I eliminated other options.A,B moving mysteriously.C "that" is wrongly placed
D-same as C.I found E as grammatically correct although it is wordy.
I don't understand the OA.
Please explain.

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.

A: 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
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
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.

Hi prachi18oct,

Answer B is correct.

From your post, it sounds like you eliminated B (and A) because of the adverb "mysteriously," which describes how the pearls move from one necklace to another. In fact, it's a perfectly correct use of the adverb. In any case, all of the answers contain one form or another of the verb and adverb, so that is not a reason for eliminating any of the answers.

Answer B, "like pearls moving mysteriously from one necklace to another," is a correct metaphor (a simile, in fact), comparing how genes jump with the way pearls move.

I hope this helps.

Hi Experts,
Is it an Official question ?

Hi Mitch,

Is the usage of that in CDE also the problem?
Moreover, can you tell the distinction between to others and to another ?

Generally, a modifier should be AS CLOSE AS POSSIBLE to what it modifies.
C and D: pearls do that move
Here, that move -- an adjective serving to modify pearls -- should be as close as possible to pearls, as follows:
pearls that move.
Eliminate C and D.
Moreover, can you tell the distinction between to others and to another ?
others (a plural pronoun) must have a plural referent.
another (a singular pronoun in A and B) must have a singular referent.
In C and D, others (plural) cannot serve to refer to necklace (singular).
Eliminate C and D.
