Truth-Tables-and-Venn-Diagrams-and-Center-Objects-by-Justin-Coslor-2021-10-08 With Truth Tables and Venn Diagrams, if there is an odd number of objects there is always a center object and then the group of objects gets treated as one object. Then if there is another object the two (or more even number of objects) are separate until yet another object or contextual relation is introduced and that results in a center object again and then the whole group of those objects can be represented as one object.
