Question 1 Report
| Row | Statement |
|---|---|
| A | higher yields per hectare |
| B | reduced use of pesticides |
| C | genes may pass to wild plants |
| D | crops can resist insect attack |
The table lists statements about genetically modified crops. Which one is a disadvantage?
Answer Details
Higher yields, reduced pesticide use, and insect resistance are all benefits of GM crops, so the odd one out is the drawback. The disadvantage is that genes may pass to wild plants, the environmental risk that a modified gene could escape into wild relatives. The other three statements are all advantages, so they cannot be the disadvantage being asked for.
