Answer:
Reduce the amount of CO2 in the air. ...
Increase the planetary temperature. ...
Make the planet breathable. ...
Construct plants for generating super-greenhouse gases made of complex combinations of carbon,chlorine and flourine. To successfully make Mars Earth-like, we would need to raise temperatures, have water stably remain in liquid form and thicken the atmosphere. ... The only greenhouse gas on the Red Planet that's abundant enough to provide significant warming is carbon dioxide (CO2), they noted. Man cannot alter the environment in Mars to make it more suitable for human habitation. It is virtually and logistically impossible to do so for various reasons. For this to work, you need massive changes in the environment which is not possible with what we have today. Transforming Mars into a life-friendly world doesn't have to be a herculean planet-wide effort. Humanity could make patches of the Red Planet habitable relatively cheaply and efficiently by placing thin layers of silica aerogel on or above the Martian surface, a new study suggests. Proponents of terraforming Mars propose releasing gases from a variety of sources on the Red Planet to thicken the atmosphere and increase the temperature to the point where liquid water is stable on the surface. These gases are called “greenhouse gases” for their ability to trap heat and warm the climate. Scientists have considered placing Mylar disks, with a diameter of 155 miles and a weight of 200,000 tons, to reflect sunlight onto Mars and heat the surface. The idea is that over many years, the rise in temperature would release greenhouse gasses.
No, "the" is not a preposition as it does not describe a place in which something is. "The" would be called an article, like "a" or "an".
The answer to your second question, therefore, is D. Joanna hid the gift behind the couch, as "behind" would be the preposition because it describes where the gift is.
I hope this helps!
