Consider the following activities:
- 1.Spraying pesticides on a crop field
- 2.Inspecting the craters of active volcanoes
- 3.Collecting breath samples from spouting whales for DNA analysis
At the present level of technology, which of the above activities can be successfully carried out by using drones?
- A.1 and 2 only
- B.2 and 3 only
- C.1 and 3 only
- D.1, 2 and 3
▶ Answer & Explanation
Correct answer: D. 1, 2 and 3
Drones equipped with specialized payloads are capable of agricultural spraying, thus enabling targeted and efficient application of pesticides. Similarly, advanced drones with robust sensors and heat-resistant capabilities can survey active volcanic craters from a safe distance. Furthermore, drones can be outfitted to collect biological samples, such as breath aerosols from whales, facilitating scientific research and conservation efforts without direct human intervention.
