Below Is a Scenario That Raises a Moral Question

Below is a scenario that raises a moral question. Using the strategies described in Chapter 10 of Doing Practical Ethics, develop an Argument from Analogy that addresses the moral question and represent it in standard form. Then, write a brief paragraph of supplementary information for each premise (explaining what the premise is saying and why we should think it is true).
The scenario: The Case of Henry Rayhons: Donna Lou Rayhons developed dementia when she was in her late seventies and, just before being admitted to a nursing home, could not recall her daughters' names and sometimes expressed confusion about how to do things she previously could do (like eat hamburgers). She and Mr. Rayhons had sex in the nursing home until the doctors told Mr. Rayhons that she was not competent to consent. Mrs. Rayhons sometimes initiated the sexual contact, and she often showed
signs she enjoyed it, and she never showed any signs that she resisted it. Was it morally permissible for Mr. Rayhons to have sex with his wife?
