What did a surplus of food lead to in early societies?

• A. Population decline.
• B. Increased disease.
• C. Loss of trade.
• D. Job specialization.

Answer: (D)

Having a surplus of food means there is more than enough to feed everyone, so not everyone has to spend all their time farming. This freedom allows people to specialize in different tasks—making tools and pottery, weaving, trading, building, administering communities, and keeping records. When several people focus on different roles, the overall productivity of the society increases, and it paves the way for larger, more complex communities. This is why job specialization is the best answer: surplus food directly enables people to pursue activities beyond farming. The other ideas don’t fit as the primary outcome: surplus doesn’t inherently cause population decline; while dense settlements can bring disease, that isn’t the immediate consequence of having surplus; and surplus tends to promote exchange rather than eliminate trade.
