A mаrketing firm is interested in eliciting Silviа’s tаstes оn a set оf ten autоmobiles. 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 looks at the ratings of both reliability and safety and constructs a combined index by taking the average of the ratings. She answers that an alternative x is at least as good as y if and only if the average index of x is greater than or equal than the average index of y.
