The Green Revolution

• discouraged the mechanization of agriculture.

• decreased the energy subsidy of most food.

• encouraged the use of monocropping.

• pertained to leafy green plants only.

Which of the following is a typical change in genetically modified organisms?

• increased reliance on pesticides

• increased resistance to extreme weather

• decreased crop yield

• increased genetic diversity

The energy subsidy in modern agriculture

• reduces financial cost for food.

• identifies the additional energy beyond the sun added to food.

• provides economic benefits for farmers as well as consumers.

• can appear to be a violation of the Second Law of Thermodynamics.

Two farmers growing corn received a cash loan from a federal stimulus plan. They used the loan to purchase updated equipment to harvest corn faster, and to purchase genetically modified seeds. Both farms increased their output by over 85 percent compared to the same month last year.

Which of the following correctly identifies the claim from the text?

• Cash loans to farms has a negative impact on output.

• Genetically modified seeds have adverse impacts on human health.

• Updated mechanization can increase farm output.

• The farmers harvested corn at the same rate as previous years.
