Paper 1 · People, Development and Environment
Statement 1: Nitrogen oxides, sulphur oxides and carbon oxides are primary air pollutants that contribute to acid deposition. Statement 2: Atmospheric pollutants are mainly present in the troposphere and lower stratosphere. Statement 3: Persistent pollutants remain in the environment for a long time, such as pesticides, plastics and nuclear waste, while non-persistent pollutants break into simple products, such as garbage. Which of the above statements are true?
- Nitrogen, sulphur and carbon oxides are primary air pollutants contributing to acid deposition
- Atmospheric pollutants are mainly present in the troposphere and lower stratosphere
- Persistent pollutants remain long in the environment, while non-persistent ones break into simple products
AOnly statements 1 and 2 are true
BOnly statements 2 and 3 are true
COnly statements 1 and 3 are true
DStatements 1, 2 and 3 are true ✓ Correct
Correct answer: (D) Statements 1, 2 and 3 are true — All three statements are true, so that is the answer.
Explanation
★All three statements are true, so that is the answer.
★The oxides of nitrogen, sulphur and carbon are primary pollutants that cause acid deposition.
★Atmospheric pollutants do gather mainly in the troposphere and lower stratosphere.
★Persistent pollutants last long, while non-persistent ones break down into simple products.
★So each of the three statements is true.
★So the answer is statements 1, 2 and 3.
