Now that so much data travels via light--i.e., is carried in glass fibers rather than by electrical current--one goal of semiconductor research is to develop a silicon chip that can transmit and receive light signals directly, a development that may one day lead to smaller, faster semiconductors.
(A) to develop a silicon chip that can transmit and receive light signals directly, a development that may one day lead
(B) to develop a silicon chip with the capability of transmitting and receiving light signals directly, which may one day lead
(C) the development of a silicon chip that has the capability of transmitting and receiving light signals directly, a development maybe one day leading
(D) developing a silicon chip that can transmit and receive light signals directly, which may one day lead
(E) developing a silicon chip with the ability to transmit and receive light signals directly, with this development maybe one day leading
Ans A
請問
A says: to develop .... [an action], a development that..... [同位語]
C says: the development .... [a noun], a developmentthat....[同位語]
in C, apposition uses a development as a noun to describe "the development" as a noun
why this is no better than (in A) using a noun to describe an action?
