Passage Summary: A study found that many people over 65 are malnourished even if they aren't poor, but for younger people, being poor doesn't necessarily mean you are malnourished.

Reasoning: Data indicates that while more seniors are malnourished than are poor, the reverse is true for those under 65, where poverty rates exceed malnourishment rates.

Analysis: This is a Paradox question with an 'EXCEPT' modifier, meaning four options will provide a plausible explanation for the discrepancy and one will not. The central mystery is why the elderly suffer from malnourishment at rates higher than their poverty levels suggest, while younger populations seem more resilient to malnourishment despite higher poverty. To resolve this, we need information that distinguishes the two groups, such as physical health issues in seniors or social safety nets for the young. The incorrect answer will likely be irrelevant to the age-based gap or might even make the discrepancy harder to understand.
