Which statement best captures both an advantage and a limitation of using UAVs for larval habitat mapping?

• A. Advantage: high-resolution data; Limitation: requires no regulatory permissions.
• B. Advantage: rapid mapping over large areas and detection of hidden breeding sites; Limitation: cost, need for skilled operators and regulatory constraints.
• C. Advantage: eliminates fieldwork; Limitation: weather always disrupts flights.
• D. Advantage: always lower cost; Limitation: data cannot be used for planning.

Answer: (B)

This question tests how UAVs balance what they can deliver with the real-world limits of using them for larval habitat mapping. The strongest pairing is that UAVs enable rapid mapping over large areas and can detect hidden breeding sites that ground surveys might miss, offering a broad, high-resolution view of potential habitats. But this comes with real constraints: the upfront and ongoing costs of equipment and data processing, the need for trained operators and analysts, and regulatory requirements for flight permissions and airspace usage. Weather and maintenance can also affect operations, so flights aren’t always feasible. Together, the described advantage and limitation capture the practical trade-off: you gain speed and breadth plus the ability to find elusive sites, but you pay in cost, need for expertise, and regulatory hurdles. Other statements either misstate the regulatory aspect, overstate simplicity (no permissions or always disrupted by weather), or claim universally lower costs or unusable data for planning, which doesn’t reflect how UAVs actually perform in the field.
