Read the passage: 'Before you throw away those leftover vegetable scraps, consider giving them a second life. Carrot tops, celery leaves, and onion skins that typically end up in the trash can be simmered into a rich, flavorful vegetable broth. Not only does this save money, but it also reduces food waste and makes use of nutrients that would otherwise be lost.' What is the PRIMARY PURPOSE of this passage?

The PURPOSE of a passage is WHY the author wrote it — what effect or outcome they intended. Common purposes: INFORM (present facts or information to increase knowledge); PERSUADE (convince the reader to think or act a certain way); ENTERTAIN (engage and amuse); DESCRIBE (paint a picture of something). In this passage: TONE: practical, encouraging ('consider giving them a second life' — a gentle suggestion, not a command); STRUCTURE: presents a problem (food waste), offers a solution (broth from scraps), gives reasons why it's beneficial (saves money, reduces waste); LANGUAGE: positive and helpful ('rich, flavorful broth'); no harsh criticism; CONCLUSION: benefit-focused ('nutrients that would otherwise be lost'). The PURPOSE is primarily to INFORM and GENTLY PERSUADE the reader to adopt this practice. RULING OUT WRONG ANSWERS: Option A (criticize) — the tone is not critical or judgmental; it's encouraging; Option C (detailed recipe) — no specific measurements or full recipe is given; the passage is conceptual; Option D (environmental impact of landfills) — mentioned tangentially (food waste is reduced) but is NOT the primary focus. PURPOSE-TONE STRATEGY: (1) Ask: Is the author trying to teach me facts? (inform) or change my behavior/opinion? (persuade) or make me feel good? (entertain); (2) Look at the language — emotional? Neutral? Critical? Positive?; (3) Look at the structure — does it build an argument? Or present facts? Or tell a story?; (4) The primary purpose is the MOST IMPORTANT reason, not every secondary effect the passage may have.
