What was not a factor that encouraged settlement in the west in the late 1800s

A year later after the beginning of the 1812 War, which was a military conflict between the British Empire and the US, a great number of white population moved Westward and settled down on the West lands of the country. The factors that motivated those settlers to live there were the opportunities which could be possible to achieve by working the land as well as the lure of silver and gold. However, the native population that still remained on this side of the country  was not one of the positive factors which encouraged people to settle down. Despite of this, the Westward movement allowed the government to push the natives far away.

i believe the answer is:

-   william jennings bryan is a democrat while mckinley was a republican

at that time, the segment of population that choose for democratic party were the voters with low economic background and vice versa

- william jennings has support of populists and wants to have inflation to farmers while mckinley has support of bankers and businessmen , doesn't want inflation

the fixed value of gold make the large business able to stack up their gold without   being worried that it would devaluated.

- william jennings supported the silver standard while mckinley supported the gold standard

according to jenning, using other metal beside gold could the poor people to have more purchasing power and them advance in the society.

i need to see the answer to answer the question
