Question
- A. Reducing blood oxygen levels
- B. Causing respiratory problems
- C. Contributing to acid rain
- D. Increasing greenhouse gas emissions
Answer
The correct option is Causing respiratory problems. This answer is correct because it matches the approved learning objective to compare the effects of carbon monoxide, particulates, sulfur dioxide and oxides of nitrogen in the subtopic Properties and effects of atmospheric pollutants.
Explanation
The correct option is Causing respiratory problems. Causing respiratory problems is correct because it directly supports the approved learning objective to compare the effects of carbon monoxide, particulates, sulfur dioxide and oxides of nitrogen. This belongs to the subtopic Properties and effects of atmospheric pollutants within Common atmospheric pollutants and their sources, 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 Properties and effects of atmospheric pollutants.
Common mistake
Confusing Pollutants
Students often confuse the effects of carbon monoxide with those of sulfur dioxide, thinking they have similar health impacts.
Remember that carbon monoxide is toxic because it reduces the blood's ability to carry oxygen, while sulfur dioxide can cause respiratory problems and contribute to acid rain.
