The discovery of glass being expandable and able to be shaped by human breath revolutionized glassworking to such an extent that today "glassblowing" has become the generic term for all glassworking, whether the glass is blown or formed by other techniques.

B of glass that is capable of expansion and

E that glass can be expanded and

答案是E，但是想求问各位大神，虽然B没有E简洁，但是expand不是主动发出的吗？怎么用被动呢?

(B) The discovery of glass that is capable of expansion and shaped by human breath revolutionized glass working

(E) The discovery that glass can be expanded and shaped by human breath revolutionized glass working

(E)是正确的parallel structure；
(E)的意思应该是 glass can be expanded (by human breath) and shaped by human breath吧
