Scientists have recently discovered that the ultrathin, 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 (主詞是construction ,所以動詞are 有誤)
B: wings, which is the same one that makes some butterflies shimmer via the phenomenon of iridescence, that also enables (which指涉不清)
C: wings is the same as the one that makes some butterflies shimmer via the phenomenon of iridescence, enabling (the same as ,enabling )
D: wings—the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enables (看起來似乎沒有錯,用破折號解釋前面那現象,後面的動詞也沒錯,就是多了個also)
E: wings—of the same construction that makes some butterflies shimmer via the phenomenon of iridescence—also enable (主詞是單數,動詞也應是單數)
我選C,請教各位意見
