A student drafts a paragraph about public comment periods. [1] Public comment periods can make agency decisions more transparent by allowing residents to respond before rules are finalized. [2] Agencies should therefore explain proposed rules in plain language before requesting feedback. [3] Some comments may be repetitive or outside the agency's authority. [4] Nevertheless, clearer explanations can improve the quality of public input. Which sentence should be moved to improve coherence if the paragraph's main purpose is to justify plain-language summaries?
