In cradle-to-grave life cycle assessment, which stages are included?

• A. Design, marketing, sales, service
• B. Extraction, manufacturing, use, end-of-life
• C. Packaging only
• D. Transportation only

Answer: (B)

The main idea being tested is that cradle-to-grave life cycle assessment accounts for a product’s environmental impact from the very beginning of its existence to its final disposal. It covers all stages: extracting raw materials from the earth, processing and manufacturing the product, distributing and using it, and finally dealing with end-of-life options like recycling or disposal. This full-scope view is why the best choice includes extraction, manufacturing, use, and end-of-life. The other options focus on only one part or a narrow aspect (like packaging or transportation) or on stages that aren’t part of the cradle-to-grave span, so they don’t describe the complete life cycle.
