Which of the following can be logically inferred from the above statements?
Logical Inference: R2D2 Robot Abilities
We analyze the given statements to find the logical inference:
- Premise 1: R2D2 is a robot.
- Premise 2: R2D2 can repair aeroplanes.
- Premise 3: No other robot can repair aeroplanes.
Deriving the Conclusion
Premise 3, stating that no other robot can repair aeroplanes, combined with Premise 2 (R2D2 can repair aeroplanes), establishes R2D2's uniqueness among robots for this specific ability. Option 3 states: "R2D2 is a robot which can repair only aeroplanes."
- The first part, "R2D2 is a robot," directly follows from Premise 1.
- The second part, "which can repair only aeroplanes," emphasizes R2D2's unique skill. Premises 2 and 3 confirm R2D2 has this skill, and it's exclusive to R2D2 among robots. Option 3 highlights this unique capability as the defining characteristic presented for R2D2 in the context of robots.
Therefore, R2D2's identity as a robot is exclusively associated with its ability to repair aeroplanes, as presented in Option 3.
