Passage: Rising food prices have pushed many low-income families toward less nutritious, calorie-dense diets, raising concerns about long-term public health. Agricultural economists point to supply chain inefficiencies, not just production shortages, as a major driver of price volatility. Improving storage and transport infrastructure, they argue, could stabilize prices more effectively than short-term subsidies alone. Question: In the passage, the word ‘volatility’ most nearly means:
A. Complete stability over time
B. Gradual, steady decline
C. Government control
D. Tendency to change unpredictably ✅
