The Green Morning

Answer

Benjamin Driscoll is the protagonist. He is a settler on Mars who works hard to plant trees and make the air fit for humans to breathe.

Answer

He is called slight because his body is thin and delicate. Mars's thin air has made him weak and tired, so his body is not strong like an Earth-normal body.

Answer

His main mission is to plant many kinds of trees so that they will make oxygen. He wants Mars to have air that humans can breathe more easily.

Answer

He compares himself to Johnny Appleseed because both plant trees across land. Driscoll says he is doing more because he is planting many trees to make air for the lungs, not only fruit for the stomach…

Answer

Johnny Appleseed is a legendary figure from a school story who walked across America planting apple trees. Driscoll uses him as a comparison to explain his own tree-planting mission.

Answer

Thin air makes him tired very quickly and makes breathing difficult. He feels that breathing on Mars does not satisfy the lungs the way Earth air does.

Answer

He means that air is necessary for life. On Mars, the air is too thin, so people need more oxygen, which is why planting trees becomes important.

Answer

The doctor tells him that the air is very thin and that some people cannot take it. He says Driscoll may have to go back to Earth.
