Read the following statements about genetically engineered plants. Select the ones that are advantageous .
I. The increased yield from genetically engineered plants allows a smaller area of land to be farmed.
II. Generally engineering plants may have improved nutritional value .
III. Some plants can be genetically modified to give resistance to diseases.
IV. There is more research needed on the long term effects of genetically engineered crops on the environment
V. The use of genetically engineered crops may explain the increase in allergies in children

Options

A. I , II and III only
B. III , IV and V only
C. II , III and IV only
D. I , IV and V only

Answer

To determine which statements about genetically engineered plants are advantageous, let's analyze each statement one by one:

1. **Statement I**: "The increased yield from genetically engineered plants allows a smaller area of land to be farmed."
- **Analysis**: This statement is advantageous. Genetically engineered plants often have higher yields, which means that farmers can produce more food on less land. This is beneficial for food security and can help reduce the pressure on natural habitats.

2. **Statement II**: "Generally engineering plants may have improved nutritional value."
- **Analysis**: This statement is also advantageous. Genetic engineering can enhance the nutritional content of plants, making them healthier for consumption. For example, biofortified crops can provide essential vitamins and minerals.

3. **Statement III**: "Some plants can be genetically modified to give resistance to diseases."
- **Analysis**: This statement is advantageous as well. Genetic modification can make plants more resilient to diseases, reducing the need for chemical pesticides and increasing crop survival rates.

4. **Statement IV**: "There is more research needed on the long term effects of genetically engineered crops on the environment."
- **Analysis**: This statement is not advantageous. While it is true that more research is needed, this statement highlights a concern rather than a benefit of genetically engineered plants.

5. **Statement V**: "The use of genetically engineered crops may explain the increase in allergies in children."
- **Analysis**: This statement is also not advantageous. It suggests a potential negative impact of genetically engineered crops, which does not support the idea of their benefits.

### Conclusion:
The advantageous statements are:
- I: Increased yield allows for smaller land use.
- II: Improved nutritional value.
- III: Resistance to diseases.

Thus, the correct advantageous statements are I, II, and III.
