Define the relation R = A x B such that (letter, word) is in the relation if that letter occurs somewhere in the word. Choose the correct relation R. O R = {(t, proposition), (t, proof), (p. proposition), (p. proof), (c, math), (c, proof)} O R = {(t, math), (p, proposition), (p, math), (p, proof), (c, math), (c, proof)} O R = {(t, proposition), (t, math), (t, discrete), (p. proposition), (p, proof), (c, discrete)} OR = {(t, discrete), (p. proposition), (p, math), (p. proof), (c, math), (c, discrete)}
29. The complementary relation R is the set of ordered pairs {(a, b)|(a, b) € R}. Let R be the relation, R = {(a,b)|a divides b} on the set of positive integers. Thus, R equals to A.

Implement the following Racket functions: Reflexive-Closure Input: a list of pairs, L and a list S. Interpreting L as a binary relation over the set S, Reflexive-Closure should return the reflexive closure of L. In mathematics, the reflexive closure of a binary relation R on a set X is the smallest reflexive relation on X that contains R. (https://en.wikipedia.org/wiki/Reflexive_closure) Examples: (Reflexive-Closure '((a a) (b b) (c c)) '(a b c)) ---> '((a a) (b b) (c c)) (Reflexive-Closure '((a a) (b b)) '(a b c)) ---> '((a a) (b b) (c c)) (Reflexive-Closure '((a a) (a b) (b b) (b c)) '(a b c)) ---> ((a a) (a b) (b b) (b c) (c c)) (Reflexive? '() '(a b c)) ---> '((a a) (b b) (c c)) You must use recursion, and not iteration. You may not use side-effects (e.g. set!).
