Final answer:
Following the Spanish-American War, Caribbean and Central American nations were deeply indebted to European countries. The U.S. aimed to counter European influence by paying off these debts, leading to American economic leverage over these nations, which they often resented as a new form of imperialism.
Step-by-step explanation:
Following the Spanish-American war, nations in the Caribbean and Central America were deeply in debt to European nations (option A). After the war, the reality for these countries was characterized by increased economic dependence on the United States, compulsory trade relationships, and the challenges posed by shortages, rationing, and price controls. The situation was further complicated by the policies of President William Howard Taft, who aimed to prevent European interference through gunboat diplomacy, ultimately leading to Central American countries becoming indebted to the U.S. instead.
