Options A, B, and C are correct. The source document incorrectly instructed the reader to select two and omitted Option B, even though Anthropic explicitly recognizes tone and style as valid evaluation dimensions. The question has therefore been corrected to “Select three.”
Factual accuracy measures whether claims faithfully reflect the supplied sources. Style consistency evaluates whether the brief follows the organization’s established voice, terminology, and audience expectations. Format and length compliance determine whether Claude followed explicit deliverable constraints. Together, these criteria cover factual fidelity, audience suitability, and instruction adherence.
Option D is not a sound criterion because an external industry word-count benchmark may have no relationship to the actual business need. The relevant measure is compliance with the requested length and sufficient coverage of the required material. Option E is also invalid as written: an executive summary is required only if the task specification, template, or audience needs call for one. Automatically demanding it would evaluate an unstated requirement.
Anthropic’s evaluation documentation identifies task fidelity, relevance, tone and style, context utilization, and other task-specific success criteria as valid dimensions. It also stresses that criteria should be specific, measurable, achievable, and relevant. See Anthropic’s official evaluation guidance .
