Solution 1
| Sr. No. | Advantages | Disadvantages |
| 1. | Genetically modified (GM) crops have shown a significant increase in crop yield and productivity. | There could potentially be a reduction in the genetic diversity of crops. |
| 2. | GM crops show resistance to pests and diseases, reducing the need for chemical pesticides. | They could potentially harm non-target organisms such as beneficial insects. |
| 3. | GM crops can tolerate abiotic stresses such as drought and salinity. | Altered gene expression in GM crops may lead to unforeseen negative effects. |
| 4. | GM crops like Golden Rice, enriched with Vitamin A, offer enhanced nutritional value. | There are potential health risks such as allergenicity or toxicity in genetically modified food. |
| 5. | The use of GM crops reduces agrochemical usage, thus lowering environmental pollution. | Farmers’ dependence on biotech companies for GM seeds raises socio-economic and ethical concerns. |
Solution 2
| Sr. No. | Feature | Advantages | Disadvantages |
| 1. | Agricultural productivity | Enhances crop yields, helping to address food shortages and increasing farmers' income. | It can create a cycle of dependency for farmers, who must purchase patented seeds annually at high costs. |
| 2. | Environmental impact | Reduces the use of chemical pesticides on insect-resistant crops. Can promote more sustainable farming practices like no-till agriculture. | Increases the risk of creating herbicide-resistant "superweeds" and negatively impacts biodiversity. |
| 3. | Human health | Improves nutritional content through biofortification (e.g., Golden Rice). Reduces human exposure to pesticides. | Raises concerns about potential allergens, the creation of new toxins, and antibiotic resistance. |
| 4. | Economic and social factors | Can lower food prices and provide economic benefits to farmers. | Concentrates power within a few multinational corporations, which can threaten local agricultural diversity. |
