<em>Around 2,200 miles.</em>
Explanation:
The Indian Removal Act was passed in 1830, this meant that many Native Americans had to move from their tribal lands to what is now present-day Oklahoma. If they did not move, they would have to be forcefully removed by the United States military and unfortunately, that was the case for many.
A lot of the Natives realized they did not stand a chance against the United States government, so they left by themselves and tried to avoid confrontation. Many of the Cherokee Natives did not want to move and even tried begging to stay in their homeland. The United States government did not budge and wanted to still move them to Oklahoma in order to expand.
Eventually, the Cherokee Natives were forced out and had to walk 2,200 miles to what is now Oklahoma, this walk is known as the Trail of Tears. The Native Americans were walked at gunpoint and many of them ended up dying from disease, weather conditions, dehydration, and other factors.
Answer: Herding animals.
In the zones of the semi-arid climate, there are huge areas of savannahs and steppes. Annual rainfall varies from 250 to 760 mm. This moisture is enough for grassy vegetation, but not enough for full forests. Severe droughts in these areas are a fairly common phenomenon. In open level spaces with rare trees prevail strong winds. The necessary conditions of existence of grassy vegetation of this zone are grazing of large herd animals which liberate vegetative communities from the accumulated straw and destroy bushes. The bulk of the plant grass mass is concentrated underground. The powerful root system allows it to accumulate nutrients and moisture. Herding animals stimulate the regeneration of vegetation.
The answer is D. Farming settlements in the Indus Valley River began being established in 4000 BCE.
