Read the draft passage. Opening paragraph: A reviewer can understand each paragraph on revising an employee handbook separately, but not the order in which the events occur. Paragraph 1: A draft is written and reviewed by managers for operational accuracy. Conflicting language is resolved before employees see it. Paragraph 2: Employees receive the proposed changes and submit questions during a defined review period. The drafting team clarifies several procedures. Paragraph 3: Human-resources staff compare the current handbook with actual practice and updated requirements. Outside specialists flag sections needing revision. Paragraph 4: Leadership approves the final handbook, which is distributed with an acknowledgment form. Training follows for policies that changed. Which paragraph order best moves from the earliest prerequisite to the final result?
