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.
(A) of glass being expandable and able to be
(B) of glass that is capable of expansion and
(C) of glass being capable of expansion and that it can be
(D) that glass can be expanded and it is able to be
(E) that glass can be expanded and
原文意思：自从发现玻璃能撑大并且能通过人吹起改变形状之后是玻璃制造业发生了重大的变革
题目分析：前面用the discovery后面用that才能把discovery的内容说清（that后面跟句子，句子说的是件事情而of后面跟短语，短语说的不是事情例如：the evidence of 英吉 who kill people强调的不是英吉杀人这件事情而是杀人的英吉这个家伙而discovery that后面所说的英吉 kill people ，强调的是英吉杀人这件事情），ABC干掉，DE进行比较，一个加了it一个没有，expand和be able to的发起者没变，加it就是英吉不仅杀人而且他放火了（这个他没必要，杀人放火都是英吉干的），选E.
