Gravity exerts a downwards force on the roots.
I'm pretty sure (1.) is A, and I know for a fact that (3.) is D because slavery was a regular practice between quarreling tribes. I have no clue what (2.) is. Best of luck.
Left Panel
I don't know how to eliminate all the choices, but the answer for this question is E.
A is incorrect. Out of 10000 cases making an appeal to the Supreme court, only 80 are hear.
B: Sometimes a case is heard if only 1 justice wants to hear it because the case is in the realm of his specialty. So B is not true.
C: C is one of those possibilities that is possible that might be true. Actually the cases presented to the court go through a pool of clerks who decide whether or not to pass it on.
D: For the same reason that B is not the answer, I don't think this one is either. The court has in recent history had an odd number of justices. I don't think the chief justice has any more votes than any of the others. The vote rarely is 4 to 4 close, especially recently.
Middle Panel
The answer to this is D to make and pass laws that apply to the state. I'll explain this better in the comments when I'm at home.
Right Panel
I think the closest answer is A. I'll put this one in the comments as well.
During the Industrial Revolution (1760-1890), people began moving to more heavily indstrualized countries. Such as Britian, France and Germany.
The conditions in the factories were bad, workers often lived in cramped spaces. They were also exposed to dangerous chemicals by the machines due to poor ventilation.
It wasn't just the chemicals, the machinery were also dangerous to operate as well.
The Industrial Revolution changed the way people lived by offering more jobs to people. The upper-class and middle-class workers were paid better and as a result, were able to move away from all the poverty.
However, the poorer workers would not get the same work hours or payment as the upper and middle class. Their standard of living had decreased as they needed to work more hours and got paid less.
