Which of the following can be logically inferred from the above statements?
We analyze the given statements to find the logical inference:
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."
Therefore, R2D2's identity as a robot is exclusively associated with its ability to repair aeroplanes, as presented in Option 3.

Based only on the information provided above, which one of the following sets of statement(s) can be logically inferred with certainty?
(i) All those students who would not be eligible to vote in the college elections would certainly belong to the Department of Human Sciences.
(ii) None of the students from departments other than Human Sciences failed to complete the registration process within the due time.
(iii) All the eligible voters would certainly be students who are not from the Department of Human Sciences.
