"I need one out of the set of boxes" is false if every box is such that
I don't need it.
"I need a box (any box)" is false is there exists a box such that I
don't need it *AND* I don't have one yet.
"I need every box" is false if there exists a box such that I don't
need it.

The first two are easy to distinguish. But how to capture the difference
between the last pair is the problem.
