Question

A. Using fossil fuels for energy
B. Implementing carbon capture and storage
C. Increasing meat consumption
D. Reducing public transport usage

Answer

The correct option is Implementing carbon capture and storage. This answer is correct because it matches the approved learning objective to evaluate methods for reducing carbon footprints in terms of cost, practicality and effectiveness in the subtopic The carbon footprint and its reduction.

Explanation

The correct option is Implementing carbon capture and storage. Implementing carbon capture and storage is correct because it directly supports the approved learning objective to evaluate methods for reducing carbon footprints in terms of cost, practicality and effectiveness. This belongs to the subtopic The carbon footprint and its reduction within Carbon dioxide and methane as greenhouse gases, 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 The carbon footprint and its reduction.

Common mistake

Misunderstanding Cost vs. Effectiveness

Students often confuse the cost of a method for reducing carbon footprints with its effectiveness, assuming that cheaper methods are always less effective.

To fix this, students should evaluate both the cost and the effectiveness of each method separately, considering how each method impacts carbon emissions and its overall feasibility.
