- C. By overlaying satellite-derived rainfall estimates with topographic maps
- D. By ignoring satellite data and relying solely on historical records
Answer
The correct answer is By overlaying satellite-derived rainfall estimates with topographic maps.
Explanation
The correct option is By overlaying satellite-derived rainfall estimates with topographic maps. By overlaying satellite-derived rainfall estimates with topographic maps is correct because it directly matches the approved learning objective to use satellite imagery as geographical data. This belongs to Use of qualitative and quantitative data within Use of qualitative and quantitative data, so the answer must stay focused on the geographical process, evidence, place, or impact named by the curriculum.
