c. agricultural shift to biofuel production
d. increased crop diversification

please select the best answer from the choices provided.

Explanation:

Analyze the question

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

Evaluate risk-increasing factors

• Water scarcity (A) directly reduces crop yields, increasing famine risk.
• Overpopulation (B) increases global food demand, straining resources and increasing famine risk.
• Agricultural shift to biofuel production (C) diverts arable land and crops away from food production, reducing food supply and increasing famine risk.

Evaluate the remaining option

• Increased crop diversification (D) improves agricultural resilience against pests, diseases, and climate fluctuations. This practice helps secure food supplies and decreases the risk of famine. Therefore, it is not a factor that increases famine risk.

Answer:

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