Read the four summarized statements regarding agricultural drone surveillance in sub-Saharan Africa. In what order should these points be arranged to form a coherent, logically structured summary from the core problem to the final long-term outcome?
- 1Recurring pest invasions routinely devastate cereal crop yields in farming communities across sub-Saharan Africa.
- 2To mitigate these severe losses, regional agricultural agencies deployed unmanned aerial vehicles to track swarm movements in real time.
- 3High-resolution sensors on these drones enable farmers to target pesticide applications precisely rather than spraying entire fields.
- 4Consequently, this localized chemical application reduces expenditure while effectively safeguarding the regional food supply.
Cevap
The correct logical sequence begins with establishing the main problem (pest invasions), moves to the technology introduced (drones), details the operational benefit (precision spraying), and concludes with the overall outcome (cost reduction and food security).
The logical sequence follows standard expository summary organization: it opens with the baseline problem (cereal crop destruction), introduces the solution (deploying drones), describes the operational mechanism (targeted pesticide application), and finishes with the broader synthesis of economic and food security benefits.
