Single or plural verb?

[Abusaad]

The development and launching of this website goes (or go???) to show his commitment to education. The contents of the website not only reflect his dissatisfaction over the falling standards of education but also his concern over the government inaction to put the things right.

Any other correction?

You could use either 'go' or 'goes' depending on whether you see them as one thing or two. I'd say 'government's inaction'.
