According to article one of the Constitution what power does the legislative branch have?

ability to establish "necessary and proper" clause

Explanation:

Government's duties are very complex. It's impossible to write all of government powers to fit in the length the of the constitution. This was the reason why the founding fathers added the power to establish "necessary and proper" clause.

This clause gave the legislative branch to establish all legislations that are necessary in order to carried out the main powers displayed within the constitution. This gave the legislative branch with a lot of flexibility to design their legislations depending on specific situations that United States face.

by 1890, the united states had by far the world's most productive economy. american industry produced twice as much as its closest competitor--britain. but the united states was not a great military or diplomatic power. its army numbered less than 30,000 troops, and its navy had only about 10,000 seamen. britain's army was five times the size of its american counterpart, and its navy was ten times bigger. the united states' military was small because the country was situated between two large oceans and was surrounded by weak or friendly nations. it faced no serious military threats and had little interest in asserting military power overseas.
