143. 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 (C)

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

不明白E哪里不平行,

E not only able to transform…but they were also able to create不平行，

应该 scientists were not only able to transform….they were but also able to create….,但they were but also...太别扭了,不知道正确的形式应该是什么?请教了!感谢!

是(were able)not (only) to....but to ...

即, not...but...结构,
