Read: 'Before storing power tools, remove batteries from cordless tools, wipe down metal surfaces with a light oil, coil cables without tight bends, and store in a dry location away from temperature extremes. These simple steps take five minutes and can extend tool life by years.' What is the PRIMARY PURPOSE of this passage?

PURPOSE ANALYSIS: What is the author trying to accomplish? The passage: lists specific actionable steps; includes a time estimate ('five minutes'); explains the benefit ('extend tool life by years'); uses neutral, instructional language. This is a HOW-TO / INFORMATIONAL purpose — teaching the reader how to maintain tools. Option A (sell products) — no products are mentioned; no commercial intent is evident; the advice is generic and actionable without any purchase. Option C (warn of dangers) — danger is not the focus; the tone is positive and practical, not cautionary; 'simple steps' and 'five minutes' signal ease, not warning. Option D (compare brands) — no brands are mentioned. PURPOSE QUESTION STRATEGY: Ask: (1) Is the author trying to teach/inform? (2) Convince/persuade? (3) Warn/caution? (4) Entertain? The dominant mode here is INFORM — providing practical information the reader can use. Many passages can do more than one thing, but the question asks for PRIMARY purpose — the dominant intention that most clearly describes why this was written.
