Final answer:
Contracts can be avoided or terminated under certain circumstances such as fraud or duress.
Step-by-step explanation:
The statement 'Once a contract has been affirmed, it no longer can be avoided' is false. Contracts can be avoided or terminated under certain circumstances, such as fraud or duress. For example, if one party entered into a contract because they were deceived by the other party's misrepresentation, they may be able to avoid the contract.
