Kenneth: Yes sure we should know more about oxygen.
John: Now I remember what Sam said, my teacher also said the same thing, that oxygen supports combustion.
Kenneth: That means oxygen supports burning.
Sam: Now this brings me to another question. Since we know that oxygen supports burning. There is so much oxygen present in air, why don't we all get burnt then?
