Final answer:
A contract is more likely to be enforceable when a) the purpose of the licensing requirement is to protect the public rather than raise revenue.
Step-by-step explanation:
When it comes to the enforceability of a contract in terms of licensing requirements, the purpose of the requirement plays a crucial role. If the purpose of the requirement is to protect the public, the contract is more likely to be enforceable. This is because protecting the public is a legitimate and important objective of licensing requirements, and courts are more inclined to enforce contracts that serve such purposes. On the other hand, if the purpose of the requirement is to raise revenue, the contract may be less likely to be enforceable as it may be seen as a means of extracting money rather than serving a public interest.
