Question

which was an effect of the active management of food supplies by early humans?
○ farmers got better at not growing more than they needed
○ the surpluses enjoyed by hunter - gatherers ran out quickly
○ people could produce more food and support denser populations
○ better management meant humans had less need for trade

Explanation:

To determine the effect of active food supply management by early humans, we analyze each option:

• Option 1: Farmers (early humans transitioning to agriculture) aimed to grow enough or more, so "not growing more than needed" is incorrect.
• Option 2: Hunter - gatherers' surpluses were limited as they relied on foraging; active food management (agriculture) was a shift from hunting - gathering, so this is incorrect.
• Option 3: With active food management (like agriculture, storage, and cultivation), people could produce more food. More food allows for denser populations as it can support more individuals. This is a key effect of improved food production and management in early human societies.
• Option 4: Better management (e.g., surplus production, specialization) would likely increase trade as people had excess to exchange, so "less need for trade" is incorrect.

Answer:

People could produce more food and support denser populations
