Answer:
a. Glittering generalities refer to words that are used to persuade an audience by appealing to their emotions but not necessarily their logic.
Explanation:
Glittering generality is such a vague word that everyone agrees on its appropriateness and value - but no one is really sure what that means. When your instructor says she's in favor of "fair evaluation policies" or "job submission flexibility," you might think, 'Hey, she's not that bad after all.' Later, however, you may find that your interpretation of these terms is quite different from what it intended.
Examples of words that often function as Glittering generalities in political discourse include freedom, security, tradition, change, and prosperity.
