When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. ... The carbon dioxide is dissolved in the blood, carried to the lungs by the circulation, and breathed out.

In "helen grey" what does the narrator suggest will be the outcome if helen grey does not change her ways

Butoxors [25]

I had the same problem with this question and I know I'm late, but I am answering it for future students who may have trouble with this question. I believe the narrator is saying that if Helen Grey does not change her ways she will be unhappy. Men think she is beautiful, but because her personality is ugly they will find her unattractive. She will be bitter. In the poem it states, "Take heed, you yet may trip and fall, and no man care to stretch his arms."
