Answer:
The focus of Article I of the Constitution is the Legislative branch of the Federal Government and its roles.
Step-by-step explanation:
Article I of the Constitution creates the Legislative branch of the Federal Government, the Congress of the United States, which includes the Senate and the House of Representatives. The article regulates how representatives and senators are elected and what requirements they must meet, and what powers Congress has.
Article I is the longest of the seven major articles of the Constitution of the United States, and it was the only article that had clauses that could not be changed until 1808 under a constitutional amendment. The clauses in question prohibited Congress from abolishing slavery and reducing the representation of a state without the consent of that state.
