Answers

Answer: Bantu expansion

Explanation: The Bantu expansion was a major series of migrations of the original Proto-Bantu-speaking group, which spread from an original nucleus around West-Central Africa across much of sub-Saharan Africa. In the process, the Proto-Bantu-speaking settlers displaced or absorbed pre-existing hunter-gatherer and pastoralist groups that they encountered.  The primary evidence for this expansion is linguistic – a great many of the languages which are spoken across Sub-Equatorial Africa are remarkably similar to each other, suggesting the common cultural origin of their original speakers. The linguistic core of the Bantu languages, which comprise a branch of the Niger–Congo family, was located in the adjoining regions of Cameroon and Nigeria. However, attempts to trace the exact route of the expansion, to correlate it with archaeological evidence and genetic evidence, have not been conclusive; thus although the expansion is widely accepted as having taken place, many aspects of it remain in doubt or are highly contested.

1. Why did the demand for slaves increase during the cotton boom?
A. More slaves were needed to construct cloth factories.
B. More slaves were needed to plant and pick the cotton.
C. More slaves were needed to transport the cotton to market.
D. More slaves were needed to sell the cotton to cloth factories.

Answers

1: While it was true that the cotton gin reduced the labor of removing seeds, it did not reduce the need for slaves to grow and pick the cotton. In fact, the opposite occurred. Cotton growing became so profitable for the planters that it greatly increased their demand for both land and slave labor.

Why couldn't allies land in northwestern part of France ww2

Answers

The correct answer to this open question is the following.

Although there are no options attached we can say the following.

The reason why the Allies couldn't land in the northwestern part of France in World War II was that the Allies did not have air superiority in northern France in the North Sea. The Allies believed that Germany was too strong in the North with better defenses

That is why the Allies chose to land in Normandy, closer to the bases in England, and its open beaches not as heavily defended as in the North.

The code name for Normandy was "Operation Overload."

In June 1944, the Allied forces, comprised in the mission by the United States, Great Britain, Canada, France, and Poland, liberated that territory that was invaded by the German Army. After that victory, the Allied forces advanced to Berlin.

What is the meaning of the following quote and how can we see this in our
world today? "Fear, though, can also be used to do harm. Some politicians
use it to control their followers. They might want their supporters to fear
and to hate people who are different." (write a paragraph of 4-5 sentences)

Answers

Answer:

fear can lead you into danger.

Explanation:

All it means is that when a person is in great fear and still deciding on what is wrong or write, not being sure of what he or she is doing, so therefore the fear of that person can make you fail and then you can probably start doubting yourself...this just an instance tho..but fear isn't a good thing to witness.
