Final answer:
An auditor is least likely to learn of slow-moving inventory through standard financial statements; specific inventory analyses are required to identify such issues.
Step-by-step explanation:
An auditor would be least likely to learn of slow-moving inventory through a company's standard financial statements. Auditors typically rely on more specific procedures to identify slow-moving inventory, such as analyses of inventory turnover rates, physical inventory counts, and reviews of subsequent sales activity.
It is less likely for slow-moving items to be directly indicated on standard financial documents without these specific investigative procedures.
