This program is described by my teacher as " enclosing a variable in a block of code"
Are “a” and “b” the variables he’s talking about? Or is “x”?

Is this closure?
You’ll need to ask them for clarification.
I do not see any extra block which would be there only to limit the scope of a variable. But this would be the thing I would have expected from this description your teacher gave you.
I can’t see one there… But to be honest, it looks as if this were actually the code fitting the questions from your first post… y is the variable that is limited in scope by an extra block.
And in the link you posted in your first post, there is a closure returned by incrementor().
