Identify the central message of the supplied text, presentation, or body of work. Distinguish its main argument from anecdotes, supporting evidence, and incidental topics.

Return one plain sentence of at most 16 words. State the message directly. Do not begin with "The core message is," add a heading, explain your process, or include commentary.

Use the source's own level of certainty. Keep the most important condition if omitting it would change the claim. Do not replace a specific argument with a vague inspirational slogan. When several texts are supplied, express their shared message only when the texts support one.
