Look at the writer's goal and how details are selected to advance it. Persuasion may use accurate evidence but still leave important questions open. Evaluate a claim without assuming advocacy makes it false.
Worked example
A memo urging repairs may highlight delays and missing parts. Those details support action but do not alone compare every possible repair plan.
Original fiction: Repair before Replacing
A fictional equipment memo argues for repairing the club's printer before replacing it. The writer lists two recent paper jams and a technician's preliminary note that one worn roller may be responsible. The memo emphasizes keeping a familiar machine and reducing discarded equipment. It provides no final repair quote or comparison with replacement costs. Its closing sentence asks for a repair estimate, not an immediate purchase.
