Answer:
Martin Luther King Jr. was assassinated
Around a distant star, two planets similar to Earth collided and were destroyed, astronomers said today.
The somewhat speculative scenario is based on the leftovers: a ring of debris around the star that includes a million times more dust than now circles our sun.
Besides being a location of trade, the great lake housed colonial fleets for commodore Mathew Perry and was a place where ships ( war and commercial ) where being made.
Answer is: checks and balances.
Checks and balances were principles of separation of powers (shared powers) the founders added a system. Checks and balances enable that each branch of government (executive, legislative, <span>judicial</span>) exercises some control over the others branches.
I don't think I can come up with 5.
1. Both have a system of voting to decide major issues like whether or not to go to war. The difference is in who can vote. Mostly it was an issue of property in Athens. You had to own property to be able to vote. Foreigners and women were not given the vote.
2. It was a citizen's duty to debate the issues in Athens. America, when I was growing up, had a similar stance. I believe it is more repressive now.
3. The vote, once completed, was what was done. That idea in America ended with Gore vs Bush over the Florida election. And now all that can be debated is Trump. I'm not fond of the man, but I also don't like the fact that people are "at war" about whether or not he should stay in office. The cry is for impeachment, especially from some democrats. There is little hint of cooperation in that. Before all this, though once elected, a president (with the exception of Nixon) could look forward to a modicum of cooperation.
That's about what I can come up with.
