Soybean crops are often treated with herbicides to control weeds. Some soybean varieties have been genetically modified to be resistant to a specific herbicide, such as glyphosate. Outline why herbicide resistance is engineered into soybean crops and discuss one ethical or social implication of growing genetically modified herbicide-resistant soybeans.
4 marks, so the mark scheme is looking for about 4 separate creditworthy points. Making the same point twice in different words earns it once.
Outline means: Give the main points briefly. Less detail than describe, but every key step has to be there. One short line per step, in order. The marks are for coverage, not depth.
