Passage Summary: A philosophical paradox is confusing because your gut says the answer is wrong, but the logic seems right. To fix the confusion, you have to admit the answer is actually right, the starting facts were wrong, or the logic was broken.

Reasoning: A paradox involves a conflict between intuition and logic; solving it requires rejecting the conclusion's falsity, the premises' truth, or the logic's validity.

Analysis: This is a 'Must be True' question, so we need to find a statement that is guaranteed by the text. The text gives us an exhaustive 'either/or/or' requirement for solving a paradox. If someone has successfully solved a paradox, they must have done at least one of those three things. Conversely, if someone refuses to do any of those three things, they haven't solved the paradox. Look for an answer that logically follows from this set of requirements.
