Dear teachers,

I have two questions to ask:

No.1

This area is often ________ as China's Silicon Valley.
a. referred to b. looked upon
The key is 'a'. But I think 'b' is also correct. The difference is meanings. 'a' means 'is called' while 'b' means 'is regarded'. Is that right?

No.2

Courage means moving forward _______ you are afraid that you might not accomplish what you want.
a. even if b. even though
The key is 'b'. I think 'a' and 'b' used to bear different meanings. 'a' refers to something in the future. 'b' refers to something that has already taken place. But it seems there is no difference now. Is that right?

Looking forward to hearing from you.

Thank you in advance.
