Necessary AssumptionDiff: Medium
Logic Breakdown
Passage Summary: A dietitian suggests that if you want to keep eating salt but stay healthy, you should eat fresh fruits and veggies because their potassium fights the salt's bad effects.
Conclusion: People should choose fresh produce over canned or frozen options to protect their hearts without reducing sodium intake.
Reasoning: Potassium helps mitigate the negative effects of sodium, and fruits and vegetables contain potassium.
Analysis: The dietitian assumes there is a meaningful difference in potassium levels between fresh and processed produce. If canned or frozen vegetables had just as much potassium and no extra sodium, the recommendation to specifically choose fresh would be logically unnecessary. Look for an answer that confirms fresh produce is actually superior in its potassium-to-sodium ratio for this specific purpose.

Correct Answer

The conclusion prefers fresh over canned/frozen because potassium helps. That only follows if fresh produce has more potassium than the canned/frozen alternatives. Negation test: if fresh does not have more potassium, the reason given no longer supports choosing fresh.
