D)The manager thinks that when the employees are in positive moods, they will make valuable contributions to staff meetings. So positive moods guarantee valuable contributions, but that doesn't mean that they are necessary for valuable contributions, so Choices C and E need not be true. The manager believes that valuable contributions are necessary for successful meetings, but that does not mean that those contributions guarantee a successful meeting, and so Choice A need not be true. Nothing the manager says suggests what would guarantee a successful meeting, and so Choice B need not be true. But Choice D must be true. Since valuable contributions are necessary for successful meetings, if a meeting doesn't have valuable contributions then it cannot be successful.
