Answer 2

D. She doesn't consider phosphorous to be a Green house Gas.

Step-by-step explanation:

• Green house gases are major cause of air pollution today.
• They are becoming a big concern day by day.
• These gases are contributing to overall rise in Earth's temperature leading to Global warming.
• Mary is campaigning to improve air quality.
• Phosphorus is not a gas and is not considered as a significant air pollutant.
• But Carbon dioxide and Methane are reported to be significant green house gases in atmosphere.
• So, Mary is very much concerned about Carbon dioxide and Methane Outputs.
