Explanation:

Analyze the historical context of "America's backyard"

The phrase "America's backyard" historically refers to the sphere of influence the United States claimed over the Western Hemisphere (particularly Latin America and the Caribbean). This concept was formalized through the Monroe Doctrine (1823) and significantly expanded by the Roosevelt Corollary (1904), which asserted the right of the United States to intervene in the domestic affairs of Latin American nations to maintain economic and political stability and prevent European intervention.

Evaluate the given options

• Option 1: "The United States established tariffs for other nations." — Incorrect. The US cannot directly establish domestic tariffs for sovereign foreign nations.
• Option 2: "The United States took land in the region without paying." — Incorrect. While the US acquired territories and leased land (like the Panama Canal Zone), this does not define the overall systemic relationship of the hemisphere being its "backyard."
• Option 3: "The United States allowed Americans to immigrate to other nations in the region." — Incorrect. Migration policies do not define this geopolitical sphere of influence.
• Option 4: "The United States got involved to make sure nations of the Western Hemisphere maintain stability." — Correct. This directly aligns with the Roosevelt Corollary to the Monroe Doctrine, where the US acted as an international police power to enforce stability in the region.

• (B) The United States took land in the region without paying.
• (C) The United States allowed Americans to immigrate to other nations in the region.
