Which product is cited as an example of improving life in developing countries?

• A. Solar lights
• B. Luxury watches
• C. Gaming consoles
• D. Sports cars

Answer: (A)

The main idea here is identifying a product that directly improves daily life in developing countries by addressing basic needs like lighting, health, and education. Solar lights fit this best because they deliver affordable, off‑grid illumination. They reduce the reliance on kerosene or candles, which cuts indoor air pollution and fire risk, improving health and safety. They also extend usable hours after sunset, allowing students to study and people to work, which can boost education outcomes and household productivity. In contrast, luxury items such as watches, gaming consoles, or sports cars do not address these essential needs or have a broad, practical impact in off‑grid settings. So solar lights are the most meaningful example of improving life in developing countries.
