Answer:
Giving the Union control of the Mississippi River
Explanation:
The Union wanted control of the Mississippi to cut off trade and transport for the South. The river being taken also made things harder for the Confederates (because it cut their side in half, so the Union had the upper hand).
The correct answer is Christopher Columbus.
Christopher Columbus is the European explorer credited with being the first European explorer to encounter the Americas. In his first voyage in 1492, Columbus landed in Hispaniola (modern day Dominican Republic). This encounter lead to several other European explorers setting out to colonize these new lands as a means to gain wealth.
