Read the passage and answer the question that follows. Scientists generally agree that Earth is getting warmer due to what's called the greenhouse effect. A greenhouse used for plants stays warm because sunlight and heat coming through the glass roof are mostly trapped. The heat doesn't radiate back into the atmosphere because it's partly trapped by the glass. Something like that happens on Earth. The atmosphere acts like a blanket that keeps the Sun's heat from leaking away into space. The main conclusion you can draw from this paragraph is that ____. A. in a greenhouse, the Sun's heat is trapped by the glass. B. a greenhouse helps plants to grow faster. C. because of the greenhouse effect, plants on Earth should thrive. D. the atmosphere keeps Earth warm.

D. The atmosphere keeps Earth warm.
The main conclusion from the paragraph is that the atmosphere acts like a blanket, preventing the Sun's heat from leaking away into space and keeping Earth warm. The analogy to a greenhouse is used to explain the concept of the greenhouse effect, where the atmosphere traps heat similarly to how a greenhouse traps heat for plants.
