Aid's Impact on Sustainable Development

Steps:

• Identify long-term growth as sustained increases in productivity, infrastructure, and human capital.
• Evaluate each option: Does it create lasting assets or skills, or just temporary relief?
• Compare: Infrastructure and training build capacity; food aid addresses immediate needs without enduring benefits.
• Select the option that fails to enhance productive potential over time.

Why C is correct:

• Food distribution provides short-term consumption relief but does not increase productive capacity, per economic growth models like Solow, which emphasize capital accumulation over temporary aid.

Why the others are wrong:

• A: Irrigation systems boost agricultural productivity and output long-term.
• B: Airports improve trade, connectivity, and economic integration.
• D: Technical training enhances human capital, driving innovation and efficiency.

Final answer: C
