Question
- A. Increasing crop yields
- B. Decreasing food prices
- C. Damaging crops and livestock
- D. Enhancing soil fertility
Answer
The correct answer is Damaging crops and livestock.
Explanation
The correct option is Damaging crops and livestock. Damaging crops and livestock is correct because it directly matches the approved learning objective to explain factors affecting food supply including climate, technology, pests and disease, water stress, conflict and poverty. This belongs to Food (optional route) within Section C: The challenge of resource management, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum. The other options are weaker because they move away from Food (optional route), reverse the geographical relationship, or make a broader claim than the objective supports.
Common mistake
Misunderstanding Factors Affecting Food Supply
Students often confuse the factors affecting food supply, such as thinking that only climate impacts food availability, ignoring technology, pests, and other factors.
To fix this, students should create a comprehensive list of all factors affecting food supply, ensuring they understand how each factor contributes to food availability.
