Final answer:
A payment event must tender 1 payment.
Step-by-step explanation:
The statement 'A payment event must tender 1 payment' is true.
In the context of business transactions, a payment event refers to a situation where payment is made for goods or services received. In such cases, it is expected that a single payment be made to settle the transaction. For example, when a customer purchases an item from a store, they typically make one payment to complete the transaction. Thus, the statement is true in the context of payment events in business.
