To correctly answer this question, we need to understand the term "drone" in the context of its description and functionalities, particularly as it has been mentioned in various news reports and general knowledge resources.
- Definition of a Drone:
- A drone is typically defined as an aircraft or flying device that operates without a human pilot on board. It is controlled either remotely by human operators or autonomously via onboard computers.
- Analysis of Options:
- Option 1: "flying device that has only two pilots" - This doesn't fit the definition of a drone, as drones do not have on-board pilots.
- Option 2: "helicopter that does not have a pilot" - While remote-controlled helicopters exist, the term "drone" applies more broadly to unmanned aerial vehicles (UAVs) and not specifically to helicopters.
- Option 3: "flying device that does not have a pilot" - This matches the definition of a drone, as stated above.
- Option 4: "flying device that has only one pilot" - Again, drones do not have pilots onboard, so this is incorrect.
- Conclusion: The correct answer is Option 3: "flying device that does not have a pilot". This directly aligns with the general understanding and definition of a drone.
In summary, a drone is an unmanned aircraft that is operated without on-board crew, controlled remotely or autonomously. Therefore, 'flying device that does not have a pilot' is the right choice based on the factual definition of drones.
