Final answer:
The Constitution strengthened the national government through powers given to Congress, the supremacy of the Constitution, and the creation of a strong executive branch. These changes were important to establish a strong and unified national government.
Step-by-step explanation:
Three ways in which the Constitution strengthened the national government are:
- Powers given to Congress: The Constitution granted broad powers to Congress, such as the power to regulate commerce, coin money, and make laws. This strengthened the national government by allowing it to control important aspects of the country's economy and legal system.
- Supremacy of the Constitution: The Supremacy Clause in the Constitution declared that the Constitution and laws made under it are the supreme law of the land. This gave the national government authority over state laws, reinforcing its power and ensuring uniformity across the country.
- Creation of a strong executive branch: The Constitution created the position of President, who would serve as the head of the national government. This strengthened the government by providing a central authority and a leader who could make decisions and enforce laws.
These changes were important to the new country because they established a strong and unified national government that could effectively govern the entire nation, regulate interstate commerce, and protect the rights and interests of the people.
