Let the set A = \{a, p, q, u\}. Give your answers to this question as ordered pairs, e.g. (1,2).
a. The relation $R_1$ = \{(p, a), (p, q), (u, a), (u, p)\} is almost transitive, but is missing one ordered pair. What
ordered pair should you add to make this relation transitive?
b. The relation $R_2$ = \{(a, p), (p, a), (p, u), (u, a)\} is almost transitive, but has one too many ordered pairs. What
ordered pair should you remove to make this relation transitive?
