For each of the following relations, determine whether the relation is: Reflexive. Transitive. A partial order. A strict order. Anti-reflexive. Symmetric. Anti-symmetric. An equivalence relation. Justify all your answers. a. Ris a relation on the set of all people such that (a, b) e R if and only if a and b have a common grandparent. b. Ris a relation on Z such that (x, y) E R if and only if |x – y| < 2. c. Ris a relation on Z* such that (x, y) € R if and only if x is divisible by y. Hint: An integer x is divisible by an integer y with y # 0 if and only if there exists an integer k such that x = yk. 4.
