"Unless we can(iii)______original ideas, we will not have invention," Mr. Russell said.

B、 
C、 
D、 
E、 

答案C

解析 A quick overview of the paragraph shows that its topic is the encouragement of invention and innovation.

Again, the only one of the choices for Blank(ii)that continues the theme of encouraging invention is "aside from supporting." Finally, the second sentence emphasizes the importance for innovation of a strong patent office, and this thought is reaffirmed in the following quotation from Mr. Russell, which requires "protect" in Blank(iii).
