How did the argument over the expansion of slavery lead to the end of the Whig party, creation of the new Republican Party, and shape the Democratic
Party?

Explain the arguments put forth regarding slavery by both its defenders and
detractors.

The Civil War was inarguably fought over slavery but slavery had existed in the
United States since 1619. Why did war break out over slavery in 1861, two
hundred and thirty-three years after the first slaves arrived?

Evaluate the advantages of both the Union and the Confederacy in the Civil
War? Which proved to be most significant? Ultimately, why did the Union
prevail?

The Union had many advantages over the Confederacy. The North had a larger population than the South. The Union also had an industrial economy, where- as the Confederacy had an economy based on agriculture. The Union had most of the natural resources, like coal, iron, and gold, and also a well-developed rail system.Slavery played the central role during the American Civil War. The primary catalyst for secession was slavery, especially Southern political leaders' resistance to attempts by Northern antislavery political forces to block the expansion of slavery into the western territories.

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.
