We give a solution to a problem originally posed in a draft of J.D. Monk [4].This result is now listed as further fact 4 after theorem 2.16. In doing so, we will consider some subsets of boolean algebras. We will follow S. Koppelberg [2] for notation. In particular +, ·, and−will used as the Boolean operators, and 0 and 1 as the least and greatest element. By extension, the least upper bound of a set M will be denoted∑M
