Studies have shown that, contrary to popular belief, middle-aged people have more fear of dying than do elderly people.
Given that ...
Elderly people are closer to death than are middle-aged people,
Why is it that ...
Middle-aged people have more fear of dying than do elderly people?
Evaluate
One interesting thing about this stimulus is that it doesn't actually provide the background condition for the Paradox. We would just ask our common sense,
On Paradox questions, we don't try hard to anticipate the answer (unless it's a mathematical paradox) because the answer could take so many forms. On EXCEPT questions, we're also less likely to try to anticipate the answer, because there are essentially going to be four valid answers that we need to eliminate.
Goal
Let's find four answers that give a reason why middle-aged people would be afraid of dying or why elderly people wouldn't be.
