Question
- A. An assessment that evaluates all stages of a product's life
- B. An assessment that focuses on specific stages to support a claim
- C. An assessment that ignores environmental impacts
- D. An assessment that only considers the disposal stage
Answer
The correct option is An assessment that focuses on specific stages to support a claim. This answer is correct because it matches the approved learning objective to explain how selective or abbreviated LCAs can be misused to support a predetermined claim in the subtopic Life cycle assessment.
Explanation
The correct option is An assessment that focuses on specific stages to support a claim. An assessment that focuses on specific stages to support a claim is correct because it directly supports the approved learning objective to explain how selective or abbreviated LCAs can be misused to support a predetermined claim. This belongs to the subtopic Life cycle assessment within Life cycle assessment and recycling, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Life cycle assessment.
Common mistake
Misunderstanding LCA Misuse
Students often think that all life cycle assessments (LCAs) are objective and unbiased, failing to recognize how selective or abbreviated LCAs can be manipulated to support specific claims.
To fix this, students should study examples of how LCAs can be selectively presented and practice identifying potential biases in LCA data.
