Answer and Explanation:
1. The founders decided to create a new document when they saw that the articles of the confederation did not allow the creation of a strong government, which would leave the nation with many disadvantages, in addition to a strong disorganization that would weaken it.
2. The most important elements in this document were the creation of the central government, the unified economy and the addition of the bill of rights, which protected the people.
3. The events that created the creation of the constitution were the deficiency of the national army and the inability of the central government to collect charges. This left the nation extremely weakened and unsuccessful, as it did not promote the pursuit of national goals, strong military defense and good resource management.
