Answer:
The House of Representatives.
Step-by-step explanation:
The United States federal government is formed by three branches, executive, legislative and judicial. The legislative branch, at both the national and state levels, is formed by two houses. The upper house is the Senate, and the lower house is the House of Representatives. The members of this house must be at least twenty-five years old and are elected for a two-year period. This house can declare war.
