The voters' rankings of the three candidates are given below: 6 Voters 7 1 A ABC ACB CBA 7 BCA 5.4. Find who wins this election if the Borda method is used. 5.5. Suppose the ranked-choice voting is used for the election. Who wins the election? 5.6. From your answers to the above, do you observe whether the same candidate gets elected? [Is the question, "who should be elected?", a simple and naive question?] 5.7. Suppose the plurality rule is used for the election.
