The evidence is relevant, but it is not sufficient.
While the evidence provided in the passage supports the claim that local businesses contribute positively to local economies in certain respects, such as hiring locally and making charitable contributions, it does not present a comprehensive view that allows for a full comparison of the impact of chain stores versus local businesses overall. The evidence cited is specific to hiring practices and charitable donations in one unnamed town, leaving many other aspects of economic impact unexamined (like tax contributions, overall job creation, price competition, etc.). Additionally, the scope of the evidence is limited, as data from a single town may not generalize to other local economies. Therefore, more evidence would be required to fully support the assertion that chain stores weaken local economies across the board.
