Scientists have recently discovered that the ultrathin (singular), layered construction of a butterfly’s wings, the same as the one making some butterflies shimmer via the phenomenon of
iridescence, are enabling the insect to control how much heat energy is absorbed by its
wings and how much is reflected away.

A. wings, the same as the one making some butterflies shimmer via the phenomenon
of iridescence, are enabling
Wrong. Subject verb disagreement.

B. wings, which is the same one that makes some butterflies shimmer via the
phenomenon of iridescence, that also enables
"which" refers to wings and not ultrathin so incorrect.

C. wings is the same as the one that makes some butterflies shimmer via the
phenomenon of iridescence, enabling
Not clear what "one" refer to. But to me it is second best option.

D. wings—the same construction that makes some butterflies shimmer via the
phenomenon of iridescence—also enables
Seems correct.

E. wings—of the same construction that makes some butterflies shimmer via the
phenomenon of iridescence—also enable
Wrong. Subject verb disagreement.

A. wings, the same as the one making some butterflies shimmer via the phenomenon
of iridescence, are enabling – agreement issue
B. wings, which is the same one that makes some butterflies shimmer via the
phenomenon of iridescence, that also enables – “which” incorrectly modifies “wings”
C. wings is the same as the one that makes some butterflies shimmer via the
phenomenon of iridescence, enabling – “enabling” modifies iridescence
D. wings—the same construction that makes some butterflies shimmer via the
phenomenon of iridescence—also enables
E. wings—of the same construction that makes some butterflies shimmer via the
phenomenon of iridescence—also enable – agreement issue

Agree with D.

Subject:- the ultrathin, layered construction of a butterfly’s wings. It is singular.
Verb: should also be singular.

A. "are" :- no........
B. that:- in between subject and verb. no...
C. enabling:- no verb
D. also enables:- yeahhhh.
E. enable:- plural.

GMAT TIGER I do not agree with your reasoning for C. Because "is" is the action verb is C and "enabling" acts as a subordinate clause. Please correct me if I am wrong.

also a small note on your statement: "enabling" acts as a subordinate clause.

thats not a subordinate clause rather a modifying phrase...

Tricky. I picked C, but after seeing GT's comment on meaning getting changed, D is the best.

I thought "subordinate clause" and "modifying phrase" are same thing. They modify the main verb in the preceding clause. Is that not correct?

A phrase does not consists a verb where as a clause does.

Phrase: Harry, a non-native english speaker, aims to score 700+ in GMAT, working very hard on verbal section.
Clause: Harry, a non-native english speaker, aims to score 700+ in GMAT and is working very hard on verbal section.
Sub-ordinate clause: Harry, a non-native english speaker, aims to score 700+ in GMAT however is not being able to work very hard on verbal section.
