How do you teach fundamental logic to someone that doesn't grok it?

I was presented with this problem from a lady that taught logic at the
college level.

About the simplest thing in logic is:
Given: A => B
Given: A
Conclude: ?

What do you do with a student that can't answer that question?

My reactions boiled down to:
a) dumbfounded that someone over the age of 12 who can dress themselves
considers that a hard problem.
b) anyone who can't get that will never get that and can't be taught logic.
Hand them a shovel.

On the other hand, I have seen people that had trouble with:
Given: A => B
Given: B
Conclude: ?

That seemed to be harder to understand, and for someone that misses such
questions I can think of ways to teach them, provided they could get the
first problem right.

Any thoughts?
