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: What can be inferred about the effectiveness of short-term subsidies alone?
A. They have no impact on food prices at all
B. They have already eliminated food insecurity
C. They may be less effective than fixing infrastructure long-term ✅
D. They are considered the best possible solution
