This is the sentence that I've been thinking:
I would have gone had they been ____
a) ignorant
b) ignorance
Notice that the writer (of the question) omitted the "if", so that he could revert they and had, means that the sentence is a conditional sentence.
So, between ignorant and ignorance which one is better? In this case I'm thinking about "I'd be happy", It has an identical structure with the question, is it correct if I choose b) since it's an adjective?
Sometimes, I'm confused with what I should put after "be". Like:
I want to be a doctor (a noun)
I want to be happy (an adjective)
What's the difference? How do i know? Hope you can make me understand.
