Life cycle assessment and recycling
Question
- A. To provide comprehensive environmental data
- B. To support a predetermined claim
- C. To compare two similar products fairly
- D. To analyze all stages of a product's life
Answer
The correct option is To support a predetermined claim. This answer is correct because it matches the approved learning objective to explain why assigning numerical values to pollutant effects can involve value judgements in the subtopic Life cycle assessment.
Explanation
The correct option is To support a predetermined claim. To support a predetermined claim is correct because it directly supports the approved learning objective to explain why assigning numerical values to pollutant effects can involve value judgements. 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
Value Judgements in LCA
Students often think that assigning numerical values to pollutant effects in life cycle assessments is purely objective and based on factual data.
To fix this, students should understand that value judgements are involved because different stakeholders may prioritize environmental impacts differently based on personal or societal values.
