Teacher: Choose the sentence that goes against common sense.
Options:
- Sentence A: "The main greenhouse gas is oxygen"
- Sentence B: "The main greenhouse gas is carbon dioxide"

Student: The major atmospheric constituents, nitrogen (N 2), oxygen (O 2), and argon (Ar), are not greenhouse gases because molecules containing two atoms of the same element such as N 2 and O 2 have no net change in the distribution of their electrical charges when they vibrate, and monatomic gases such as Ar do not have vibrational modes, hence they are almost totally unaffected by infrared radiation.
The answer is Sentence A.
