Which scenario best illustrates a distinction between hunger and food insecurity?

Hunger always precedes food insecurity, so someone who is anxious about future food must already be experiencing physiological hunger and thus satisfies both definitions.

A college student with adequate daily caloric intake but chronic anxiety about affording groceries is food insecure but not necessarily hungry.

An elderly person who reports occasional meal skipping due to a lack of funds is hungry but not food insecure because hunger is physiological and economic causes are irrelevant.

A household receiving free school lunches has no risk of hunger and therefore cannot be food insecure because hunger and insecurity are identical states.
