A. They prevent government from becoming too powerful.
Explanation:
When it was time to write a new constitution, the Founders took the principles outlined in the Declaration as their source. Having recently overthrown the oppressive authority of the English, they least wanted to impose a new oppression on themselves. Consequently, its basic task was to devise a government that was strong enough to protect the fundamental rights of the individual against domestic and foreign oppression, without being so powerful or extensive as to be oppressive. Towards that end, the document they wrote, after being ratified, empowered the government and government powers, and then slowed and balanced them through a series of extraordinarily thoughtful measures.
They could have decreased protectionism. Protectionism means that they limited free trade between nations and restricted trade of foreign goods. Protectionism is widely accepted as maybe the biggest reason for the development of the Great Depression and thus if the US had decreased it, it most likely would not have happened at all.
