Suppose someone says: "If every voter strictly prefers
candidate A to candidate B then candidate B must not be
elected." How would you interpret this requirement? To
fulfill this requirement, is it necessary that the
statement above is met for each pair of two candidates
simultaneously? Or is it sufficient that the statement
above is met for just one pair of candidates? Or is the
requirement ambiguous?
