Blindness is prevented by use to which crop in poor countries?

Options

A. Wheat
B. Flavr Savr
C. Golden rice
D. Pea

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Problem**: The question asks which crop is used to prevent blindness in poor countries. Blindness can often be attributed to a deficiency in vitamin A.

2. **Identifying the Cause of Blindness**: Vitamin A deficiency is a significant cause of blindness, particularly in developing countries where access to diverse diets is limited.

3. **Exploring the Options**: The options given are:
- Wheat
- Flavor Saver (a type of transgenic tomato)
- Golden Rice
- Beef

4. **Analyzing Each Option**:
- **Wheat**: While nutritious, it does not contain significant amounts of vitamin A.
- **Flavor Saver**: This is a genetically modified tomato, but it is not specifically known for addressing vitamin A deficiency.
- **Golden Rice**: This is a genetically modified variety of rice that has been engineered to contain beta-carotene, which the body can convert into vitamin A.
- **Beef**: While it contains vitamin A, it is not a staple crop in many poor countries.

5. **Conclusion**: Golden Rice is the correct answer because it has been specifically developed to combat vitamin A deficiency and thus prevent blindness in populations that rely on rice as a staple food.

**Final Answer**: Golden Rice
