In the 1700s, James Watt caused a revolution in transportation<em> by improving steam engine technology.</em>
He was a Scottish inventor and mechanical engineer. He made improvements on Thomas Newcomen's steam engine that was patented in 1698 and widely in use at the time of Watt's birth ( 1736).
It all started when Watt was given a model Newcomen engine to repair. He realized it was very inefficient and he began to find ways to improve its performance. He designed a separating condensing chamber for the engine to avoid huge losses of steam. He patented his improvements in 1769.
A unit of measurement of electrical and mechanical power -<em> the watt</em> - is named in his honor.
The answer is: E. It became a military superpower in the world but lacked a strong economy.
During the 20th century, United states more than 20% of its GDP to be allocated into millitary spending, which make us able to become a millitary superpower and contribute greatly to the victories during the world war I.
There is a downside to this. Large allocation to millitary budget means that there would be less that can be allocated to build things such as infrastructures, loans, government sponsored jobs, etc. Which is why the economy of united states at that era was a little bit lacking.
AT&T held a monopoly in the US and Canada, throughout most of the 20th century. AT&T was the owner of the Bell System, a network of telecommunications companies which included Western Union Telegraph. For many years the slogan of the company was "One Policy, One System, Universal Service."
However antitrust regulators were not happy with AT&T and in 1974, the United States Justice Department opened a case against the company, arguing they were violating the antitrust law. This case was settled in 1982, and the company was order to break up. Hence AT&T was divided into seven Regional Bell Operating Companies.
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.
