Question

Which of these statements is a paradox?

Answer 1

a paradox is what some in American-lingo will call and oxymoron, namely, an expression that has an statement with a counterintuitive logic.

the harder I work, the more I fall behind.

what the hell? if I work harder, it should be moving ahead, but, that's not the case, I'm falling behind.

so that's a paradox, how can you work harder and fall behind?  is counterintuitive, contratry to logic, therefore paradoxical.
