Answer: discharge the contract
Explanation:
From the question, we are informed that Ruth contracts to provide Stan with fifty hours of telepathic personal coaching and that the state legislature subsequently passes a law making tele-pathic personal coaching illegal.
It should be noted that because of the law imposed by the legislature, the contract will be discharged. To discharge a contract simply means that the contract would be termination between Ruth and Stan. Such contract would cease to operate.
