Answer:
c. Believed he needed the support of Southern Democrats to pass his economic and social legislation
Explanation:
According to the historical records, President John F. Kennedy moved slowly in the area of racial justice because he "believed he needed the support of Southern Democrats to pass his economic and social legislation"
During the administration of John F. Kennedy, before his assassination in 1963, he wanted to effect so many changes in both domestic and foreign policies.
However, knowing that the Southern states most often do not support the elevation of people of color, and the fact that he needed the support of Southern Democrats to pass his economic and social legislation to make those policies a reality, he was slow in enacting Civil Right legislation so as not to anger the Southern states.
Answer:
Eli Whitney popularized the interchangeable parts.
Explanation:
Eli Whitney invented the interchangeable parts theory. This technique affected the design part of a product, by dividing it into elements that would be designed separately by maintaining a series of relationships with each other that allowed them to be assembled in order to obtain the final product. Whitney put it into practice for the manufacture of muskets for the United States military, drawing on similar work that had been done long ago by the French inventor Honore Blanc for the French army. This was the basis of parts production and spare parts.
