Explanation:

Analyze the question and identify the core objective

The question asks to identify which option is not a factor that increases the risk of a widespread famine before 2050.

Evaluate each option against famine risk

• A. water scarcity: Decreases agricultural productivity, which increases famine risk.
• B. overpopulation: Increases food demand, which increases famine risk.
• C. agricultural shift to biofuel production: Diverts arable land and crops away from food supply to fuel production, which increases famine risk.
• D. increased crop diversification: Enhances agricultural resilience against pests, diseases, and climate shocks, which decreases famine risk.

Select the correct option

Since increased crop diversification helps prevent famine rather than increasing its risk, option D is the correct answer.

Answer:

• (A) water scarcity
• (B) overpopulation
• (C) agricultural shift to biofuel production
• (D) increased crop diversification (Correct answer)
