Question

This question is based on the following passage. 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. 12. The main conclusion you can draw from this paragraph is that A. a greenhouse helps plants to grow faster. B. in a greenhouse, the Sun's heat is trapped by the glass. C. the atmosphere keeps Earth warm. D. because of the greenhouse effect, plants on Earth should thrive.

Answer 1

B. in a greenhouse, the Sun's heat is trapped by the glass.

Step-by-step explanation:

Through the text shown above we can see how a greenhouse works and relate this to the greenhouse effect that has caused serious climate changes on the planet.

We can see, from the text, that the heat of the sun, gets through the walls of the greenhouse, entering the greenhouse, however, they cannot completely cross the walls of the greenhouse to return to the atmosphere, being partially trapped in the greenhouse that remains inside hotter than the outside.

The text does not convey any statements about the greenhouse allowing plants to grow faster, about the atmosphere keeping the earth warm, let alone about the greenhouse effect allowing plants on Earth to thrive.

Answer 2

The answer is C. Because due to the atmosphere, that functions as a blanket, is what keeps the Earth warm and keeps it from leaking away.
