President lincoln issued the emancipation proclamation after
a. the union’s effectiveness at the battle of antietam.
b. the death of general jackson at chancellorsville.
c. the nation had voted to decide the issue of slavery.
d. the capture of washington, dc, by confederate forces.

The correct answer is A) The Union's effectiveness at the Battle of Antietam.

The Emancipation Proclamation was supposed to free slaves in the rebellious states (aka the Confederate States of America). Even though this document did not free the slaves in the rebellious states, as every Confederate state ignored this law, it did make it so that African Americans who escaped from the South could join the Union army in the North. This was a significant turning point of the war, as it shows that Lincoln's purpose in fighting this war is to end the institution of slavery within the United States.

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.
