Define the lexicographic binary relation as follows: for any z, y € X, we have x ɩ if and only if at least one of the following two conditions holds:¹. • ï >1 Y • ~₁ y and r₂ y. [If 1 and 2 capture how a decision maker feels about different aspects of a decision, then is one way of combining them: use aspect 1 to make decisions, but if aspect 1 does not make the decision easy, then use aspect 2 to break ties.] Explain why each of the following is true: (a) If x, y € X have r L y, then r i y.
