Answer:
C
Since all the water that was needed for irrigation was frozen into icebergs, early humans could not plant.
B. They are monotheistic religions
Because the working conditions were terrible.
In the days of the Industrial Revolution, the workday was abusive and inhuman, as it ranged from 10, 12 or even 18 hours of work. Which meant that employees simply did not have a life outside the factory environment.
Other than that, in a pre-labor time, in the first factories the working conditions were really unhealthy, especially because of the lack of safety care, accidents were common, with mutilations of people, among other things.
From what it seems, I have read this and I believe the answer to be,
"The cotton gin was one of the most amazing and tragic inventions of early America."
From my experience, I believe this is the answer because it is the starting sentence and there were no facts provided beforehand to support the claim that it was one of the most amazing and tragic inventions of early America. This answer also uses some of the basic rules of opinion statements. Such as using the term "most".
Hopefully this helped!
Happy studying!
