Answer:
For question a, it simplifies. If you re-express it in boolean algebra, you get:
(a + b) + (!a + b)
= a + !a + b
= b
So you can simplify that circuit to just:
x = 1 if b = 1
(edit: or rather, x = b)
For question b, let's try it:
(!a!b)(!b + c)
= !a!b + !a!bc
= !a!b(1 + c)
= !a!b
So that one can be simplified to
a = 0 and b = 0
I have no good means of drawing them here, but hopefully the simplification helped!

Answer:
Copying anything may be the computer program or an entertainment file, it is not a good thing as the original developers or the writers are going to feel bad since their hard work is being used by others without letting them know. However, if you are using it for academic purposes, or give them credit in your work, then the original writer will not feel that bad as he is being credited, and hence you can reuse in that case definitely, but always ensure to give the credit to the original writer.
As an example, if a film is copied like many in the past the Directors always feel bad, and they have the reason for feeling bad. The same thing is to technology.
