The north American city that’s not considered as one of the three largest city in the world could be Chicago
I’d say C.
A doesn’t make sense, they definitely could’ve domesticated animals in that time.
B doesn’t make sense either, they could’ve easily seen smoke signals, the sky wasn’t filled with them often.
C is just a weird answer. I doubt they were “passive observers” but probably the best answer to the question.
D doesn’t add up because they definitely needed agriculture/food surpluses. They were always hunting, they obviously ran out of food rather quickly.
So C is the answer.
The rising of warmed air by creating a high-pressure system below, is not a part of a normal convection cycle.
<h3>
What is the significance of a convection cycle?</h3>
A continuous process of the rising of warmer areas of gases or liquids, and the sinking motion of the cooler ones is known as a convection cycle.
In a convection cycle, the warmed air cannot rise by creating a high pressure surface below and flowing away from the surface.
Hence, option D holds true regarding a convection cycle.
