What treaty resolved the issues of unclear boundaries in the Louisiana Purchase?
A.
Paris
B.
Adams-Onís
C.
Versailles
D.
Fontainebleu
To determine which treaty resolved the issues of unclear boundaries in the Louisiana Purchase, we can eliminate options based on their historical context.
Option A, Paris, refers to the Treaty of Paris in 1783, which ended the American Revolutionary War. This treaty did not address the boundaries of the Louisiana Purchase, so we can eliminate it.
Option C, Versailles, refers to the Treaty of Versailles in 1919, which was a peace settlement after World War I. This treaty is unrelated to the Louisiana Purchase, so we can eliminate it as well.
Option D, Fontainebleu, does not pertain to a specific treaty in history, so we cannot confirm its relevance to the Louisiana Purchase. Therefore, we can eliminate it too.
This leaves us with Option B, Adams-Onís. The Adams-Onís Treaty, also known as the Transcontinental Treaty of 1819, was the treaty that resolved the issues of unclear boundaries in the Louisiana Purchase. This treaty was signed between the United States and Spain, and it established the western boundary of the Louisiana Purchase along the Sabine River and the southern boundary along the Red River.
Therefore, the correct answer is B. Adams-Onís.
