<span> "Colombian Exchange." This is the exchange of the crops, animals and resources that went between the New and Old World.
From the Americas came peppers, maize, potatoes, tomatoes, snap beans,
lima, beans, and squash. Maize and potatoes became staple crops
throughout Europe. So much so that the Irish potato crop failed, the
result was famine.
From Europe, to the Americas came wheat, rye, barley, oats and millet.
The first two crops are used in bread, a mainstay today.
The horse was a European import. When adopted by the Native Americans, the result was the Great Plains cultures.
The Americans produced vast amounts of gold and silver. However the
material was obtained, the amount imported to Europe made economies
based on money possible. This allowed more trade.
Having somewhere to go and new opportunities invigorated Europe. People
could now seek their fortune or get a fresh start. Having a destination
also increased technological development of deep ocean ships.
There is a dark side to the exchange. When Europeans first came to the
Americas they inadvertently introduced a number of diseases. These
included forms of Tuberculosis, measles, cholera, typhus, and smallpox.
Oh all the exchanges between the Native Americans and the Europeans,
disease had the most impact.
Native Americans had little immunity to any of these imported diseases.
The migration route into the Americas had been through arctic regions.
The cold acted as a "filter" preventing some diseases from entering.
During their thousands of years of isolation, the inhabitants of the
Americas had avoided the disease that swept through the rest of the
world. However, this also meant that they had no immunity, protection
from these same illnesses. </span>

Found this off of google, "Radical Republicans felt that in order for southern states to write new state constitutions they must: only allow people who had not fought against the Union to participate. President Lincoln's Reconstruction policy was designed to: reunite the South with the North quickly."
C, because that was basically one of the reasons for the Civil War as well. The Northern and Southern states were always fighting about whether slavery should expand west or not.
