A marketing firm is interested in eliciting Silvia’s tastes on a set of ten automobiles. In order to do this they ask Silvia, for each pair of alternatives (x,y), whether she finds x at least as good as y. Silvia is interested in both the reliability of the car and its safety record. She answers that an alternative x is at least as good as y if and only if x is at least as reliable as y and x has at least the safety ranking as y. Then,
a) Silvia’s answers necessarily satisfy completeness.
b) Silvia’s answers will always violate completeness.
c) Silvia’s answers may violate transitivity.
d) Silvia’s answers will have a cycle.
e) Silvia’s answers may violate completeness.
