Question
- A. Because all pollutants have the same impact
- B. Because different people may value environmental impacts differently
- C. Because numerical values are always accurate
- D. Because pollutants cannot be quantified
Answer
The correct option is Because different people may value environmental impacts differently. 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 Because different people may value environmental impacts differently. Because different people may value environmental impacts differently 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.
