Question

slash-and-burn agriculture is best defined as the process of
cutting plants and setting fires to fertilize farmland for crops.
cutting steps into a hillside to make a flat surface for crops.
using ash from fires to make farmland fertile for decades.
clearing forests to make farmland fertile for generations.

Explanation:

Slash-and-burn agriculture involves cutting vegetation and burning it to release nutrients into the soil for crop cultivation, with the fertility benefit being short-term, not long-lasting. The other options describe terracing (cutting hillside steps) or incorrect long-term fertility claims.

Answer:

A. cutting plants and setting fires to fertilize farmland for crops.
