Passage Summary: You shouldn't sacrifice your health to get money because you can't be happy if you're not healthy.

Conclusion: One should never trade their physical well-being for financial gain.

Reasoning: Happiness cannot be achieved without good health.

Analysis: This is a Sufficient Assumption question where we need to find the missing link that makes the conclusion unavoidable. The premise tells us health is necessary for happiness, but the conclusion tells us we shouldn't trade health for money. The 'gap' is the relationship between money and happiness—specifically, the argument assumes that money isn't worth having if it costs you your ability to be happy. Look for an answer that establishes that one should not sacrifice a requirement for happiness (health) just to obtain something else (money).
