147. (32726-!-item-!-188;#058&006292) By pressing a tiny amount of nitrogen between two diamonds to a pressure of 25 million pounds per square inch, scientists not only were able to transform the gas into a solid, but they also created a semiconductor similar to silicon. (A) not only were able to transform the gas into a solid, but they also created (B) not only were able to transform the gas into a solid but also creating (C) were able not only to transform the gas into a solid but to create (D) were able not only to transform the gas into a solid but also creating (E) were not only able to transform the gas into a solid, but they were also able to create 句子结构：By pressing… scientists were able not only to … but to… 平行结构。 考点：平行对称 1、 平行对称-not only… but also…，注意连接对象的形式对称（also 可以省略）。 (A) not only…but also连接对象不对称，but also之间的they多余。 (B) not only…but also连接对象不对称，were able to transform与现在分词creating。 (C) 正确，not only to transform… but to create… (D) not only…but also连接对象不对称，to transform与现在分词creating不对称。 (E) not only…but also连接对象不对称，but also之间的they were多余。
本题我选了E，我不知道什么时候but also那里代词多余，碰到这种题总是拿不定主义
