Answer:
a. The way votes are tallied can significantly alter the outcome
Explanation:
According to Arrow's Impossibility Theorem, there are three possibilities:
1. in case each voter prefers alternative X over alternative Y, it means the group prefers X over Y;
2. in case each voter's preference between X and Y remains unchanged, it means the group's preference between X and Y will also remain unchanged;
3. in case no single voter has got the power to always fix the group's preference, it means there is no dictator.
In making decision, election is not a perfect means since the way votes are calculated there is a room for discrepancy.
Answer:
The Mississipi Indians were easily defeated by DeSoto because they were infected with diseases that had no biological defenses.
Explanation:
When Hernando deSoto and his groups arrived in Mississippi, they began to get involved with local cultures and infect them with diseases (such as smallpox and measles) that the Indians had no biological defense against. This caused a large number of deaths within the native tribes of Mississippi causing a severe collapse in the social structures of the tribes and allowing them to be extremely weakened and easily fought.

Answer:
The answer is- No control Group
Explanation:
The researchers want to use 120 rural schools, however this will not work out because there are no control groups in the experiment.
A control group is the group that does not receive the offer. In this scenario, all the 120 rural schools receive the offer. The control group will help measure the attendance of teachers this school year which were not offered better pay. This will be used to determine how much the offer increased the attendance or the impact of the better pay on the attendance 0f teachers.
It will also not be good to compare this year's attendance to that of last year because the condition this year might be different when compared to last year, for instance, if this year is unusually cold compared to last year and some of the teachers caught cold and could not attend some of their classes then it is expected that there will be lower attendance when compared to last year and the better payment would not be the cause of change in attendance.
