Answer : 4. "All of the above"
Explanation :
Answer: D) All of the above Explanation: Land prices in the East were getting too expensive, and the West (Great Plains) offered an opportunity for more people to own land. Although the area suffered from extreme weather and poor soils, many people decided to take the risk and venture to the Great Plains. The government was also committed to supporting those who decided to make the move. Settlers moved to the Great Plains for several reasons. One reason was the government was offering 160 acres of land for free if the settler agreed to live on the land for five years. This was part of the Homestead Act of 1862. Some people went to the Great Plains when they heard there were minerals in the region. Gold was one mineral found in the Great Plains region. People hoped to make a lot of money by mining gold.
