Interacting groups shared skills and ideas that improved farming practices
The Berlin airlift, organized by the United States, was aimed at giving goods/resources to citizens of West Berlin. This airlift lasted roughly a year and the US provided over 2 million tons of cargo to these citizens. Without this airlift and support from the United States, West Berlin was in danger of falling under the control of the Soviet Union (who at this time already controlled East Berlin).
C, they forbid them to practice and were forcing them to convert.
The northern lawmakers needed the state to join the union instead of the confederacy, because if they joined the confederacy, the Union would be weaker. They got the Missouri on their side by allowing it to hold slaves (but that could easily be overturned, so getting the state was more of a priority than having slavery or not)
hope this helps
