Consider the ER diagram of Figure 5.5. State meaningful semantics for additional binary relationships among the entity types in the diagram and update the ER diagram accordingly with full specification of the structural constraints of the relationship types you have proposed. Can the three binary relationships among the three entity types present collectively capture the semantics conveyed by the ternary relationship type? State the condition under which the answer is "yes" and the condition under which the answer is "no."
