Answer:
Question 1: A. to set up a naval blockade along the southern coast
and B. to seize control of the Mississippi River
Question 2: A. It decreased the likelihood that European countries would help the Confederacy
D. It gave African Americans the right to fight in the war
Step-by-step explanation:
1. The Anaconda Plan was a strategy designed by the Union to limit the Confederacy's advances. The plan set out to impose a naval blockade on the southern ports and to seize control of the Mississippi River to divide the south in two and give the Union an advantage. The Mississippi River would also serve as a communications network for the Union and allow them to gain more control of the areas in the south.
2. The Emancipation Proclamation had several effects. Inside the US territory it freed black slaves in the south allowing them to join the Union army and fight against the Confederacy.
On an international scale, the proclamation tipped European support in favor of the Union and reduced the possibility that foreign countries would get involved on behalf of the Confederacy.
In general terms, it was a strategic move enacted by Lincoln to gain an advantage in the war.
