Question
- A. To reduce food waste
- B. To provide water to crops
- C. To increase soil erosion
- D. To enhance food miles
Answer
The correct answer is To provide water to crops.
Explanation
The correct option is To provide water to crops. To provide water to crops is correct because it directly matches the approved learning objective to explain strategies to increase food supply including irrigation, aeroponics, hydroponics, the new green revolution, biotechnology and appropriate technology. 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
Confusing Hydroponics and Aeroponics
Students often confuse hydroponics with aeroponics, thinking they are the same method of growing food without soil.
Remember that hydroponics uses nutrient-rich water to grow plants, while aeroponics suspends plants in air and mists their roots with nutrients.
