The Nobel prize in chemistry was awarded to three scientists for their discovery that plastic can be made electrically conductive - an advance that has led to improvements in film, television screens, and windows.
a.same as above
b.that plastic can be made electrically conductive - this advance leading
c.that plastic can be made to be electrically conductive, and this advance led
d.of plastic's ability to be made electrically conductive, with this advance leading
e.of plastic being able to be made electrically conductive - an advance that has led
Hi guys, would appreciate some help here:
a. we use "THAT" in this case because it links the DEPENDENT Clause "The Nobel prize .... their discovery" with INDEPENDENT clause "plastic can be made .."? Is my concept correct?
b. What is wrong with ----- this advance leading to?
d. It is wrong because of passive voice being used?
Thank you.
