The correct answer is true.
It is true that uneven heating of the Earth's surface creates three major climate zones. ( Tropical, Temperate, Polar).
The reason why this is correct is that the Sun is the main generator of the heat on planet Earth. Our planet radiates back that heat received from the Sun because the planet orbits around the Sun tilting every moment, changing the way the Earth receives the sunrays, and distributing the heat in the different topics and regions of the Earth. This means that the tropics receive more sun rays compared to the poles.
One good example is precisely the case of the Equator that when receiving the sun rays produces humidity in the air that is hot and goes into the atmosphere.
The correct answer is that communication is irreversible.
In the given situation, Amber is still hurt due to the things that John had said unto her, especially calling her a "slob". Though they already made up, Amber still feels upset, because she thinks that what John has said is true. John is experiencing the irreversible aspect of communication, wherein communication cannot be taken back, whatever you might have said, will stay that way. It cannot be changed nor taken back.
