Answer: B. only <em>three-fifths</em> of the enslaved population would be counted when calculating each state's representation in Congress.
The Three-Fifths Compromise was reached during the 1787 United States Constitutional Convention. The question was whether the slave population would count when determining a state total's population number, which would be used to determine the number of seats that each state would have in the House of Representatives.
The compromise that was reached was to count every three out of five slaves as a person for this purpose. It gave the Southern states a third more seats in Congress than if slaves had been ignored.
The Mongols treated the non-muslim subjects most fairly, while the Ottomans treated them the least fairly.
The Mongols were religiously tolerant because they conquered and rule through manpower rather than religion. The Ottomans were the least fair to non-muslims. It is close between the Umayyads and the Ottomans, but the only difference is the amount of discrimination (per se) held against non-muslims. While the Umayyads only had the jizya (tax paid if you were non-muslim), the Ottomans had distinctive restrictions on non-muslims. They had dress codes according to their religion and could only reside in neighborhoods who's residents were of the same religion (under the Ottomans).
Religous freedom the persute of happiness
In the age of the enlightenment people shifted their mentality, suddenly it didn't matter if you were rich or powerful, all it mattered is how smart, educated, innovative and serious you were. This led to many breakthroughs and tendency to write things down boosting the overall society's education and interest in science, tech, philosophy etc.
That's all I know (I'm more mathematically oriented) but I hope this helps.
