<em>A. A measure that allowed the U.S. government to intervene in Cuban affairs.</em>
Explanation:
The Platt Amendment was made in 1901 and had it so all treaties that were brought to Cuba had to be approved by the United States.
The United States could now intervene in Cuban affairs whenever they wanted, they wanted to protect certain interests that were on Cuba and protect the Cuban independence. The United States could also now lease or even buy certain parts of Cuban land for naval bases or even coaling stations to power certain things.
Many Cubans actually approved of the Platt Amendment, as many felt more protected and safer.
James Madison played a great role in establishment of the US as a republic. During the writing of the constitution, the founding fathers were adamant that they wanted democratic system of governance. However, they were torn between a direct democracy and a republican democracy. James Madison dismissed a direct democracy since the US is a large country and thus impossible to be governed through direct pure democracy. Instead, the father of the constitution argued for a scheme of representation in a republican setting. He especially lauded such a government since it even catered for the rights of the minority than in direct democracies.
