sorry, confused again.
7的B中有两个wings, 前一个可以理解，但后一个好像是多余的吧。也许是HIGHTGMAT上的答案笔误？

7 B中的第一个wings不能没有吧，
  第2个wings如果没有，变成了so smooth去修饰shaped，从语法角度、逻辑角度都是不对地。

The second “wings” serves as an appositive to describe the first one,thus miaking the intended meaning more clearly and unambiguously.So it cannot be ommited.
