Identify the most likely source of nutritious locally-grown food in your community

A Farmer's Market.

Explanation:

A farmer's market is a gathering of local farmers who come to sell their produce to the general public. According to a study, produce from farmer's markets has higher nutritional quality than produce from supermarkets because the vegetables and fruits are mostly fresh.

For city dwellers, these farmer's markets offer a less expensive and more convenient alternative to crowded supermarkets. Food sold in supermarkets may or may not have been grown locally.

As a result, our community's farmer's market is the most likely source of nutritious, locally grown food.

yes, it is pretty much the same thing, which is cool. : )
