A is incorrect: Extensive background is historical context, not an expectation, and it does not address the length or audience problem - it simply adds noise that can make the summary longer and less focused.

B is incorrect: This vague emphasis does not define a format, length, or audience, so it is not an actionable expectation and will not fix the overly long, untargeted output.

C is incorrect: Author names are an irrelevant detail that neither sets the output format nor identifies the audience, so they will not make the summary more concise or tailored.

D is correct: Setting expectations - the desired format (five bullets), tone (plain language), and audience (non-managerial employees) - tells Copilot how to shape the response, producing a concise, audience-appropriate summary.
