Questions: What does industrial agriculture require?

The answer is: large amounts of water.

Explanation for each option:

1. Only renewable energy sources: This is incorrect. While renewable energy sources can be used in industrial agriculture, it is not a requirement. Industrial agriculture often relies on a mix of energy sources, including fossil fuels, for machinery, transportation, and production processes.

2. No pesticides: This is incorrect. Industrial agriculture typically uses pesticides to control pests and diseases to maximize crop yields. The use of pesticides is a common practice in industrial farming.

3. Large amounts of water: This is correct. Industrial agriculture often requires large amounts of water for irrigation to support high-yield crop production. Water is essential for growing crops, especially in areas that do not receive sufficient rainfall.

4. Some fertilizer: While this is true that industrial agriculture uses fertilizers, the option "large amounts of water" is more characteristic of the requirements of industrial agriculture. Fertilizers are indeed used to enhance soil fertility and increase crop yields, but the question asks for what industrial agriculture requires, and water is a more critical and substantial requirement.

In summary, industrial agriculture requires large amounts of water to sustain its high levels of production.
