Question

1. which advancement occurred in food production?

refinement of medical procedures
restoration of contaminated ecosystems
implementation of wind and solar power
development of genetically modified organisms

Explanation:

Genetically modified organisms (GMOs) are engineered to enhance traits like yield, pest resistance, and nutritional value, directly impacting food production. Medical procedures (related to health, not food), ecosystem restoration (environmental, not food - production - focused), and wind/solar power (energy, not food - production - specific) are less relevant.

Answer:

development of genetically modified organisms
