Ix This treaty established U.S claims to Florida and gave the U.S . access to the Pacific. A Adams-Onis Treaty with Spain B Convention of 1818 with England C Treaty of Versailles with Germany D D Webster-Ashburton treaty with England

## Step 1<br />The question is asking us to identify the treaty that established U.S. claims to Florida and gave the U.S. access to the Pacific. We have four options: the Adams-Onis Treaty with Spain, the Convention of 1818 with England, the Treaty of Versailles with Germany, and the Webster-Ashburton treaty with England.<br /><br />## Step 2<br />The Adams-Onis Treaty, also known as the Transcontinental Treaty, the Florida Purchase Treaty, or the Florida Treaty, was signed in 1819 between the United States and Spain. This treaty ceded Florida from Spain to the United States and defined the boundary between the U.S. and New Spain.<br /><br />## Step 3<br />The Convention of 1818 between the United States and the United Kingdom set the 49th parallel as the border from the Lake of the Woods to the Rocky Mountains. It also allowed for joint occupation of the Oregon Country for ten years.<br /><br />## Step 4<br />The Treaty of Versailles was signed in 1919 and ended World War I. It involved many countries, including Germany, but it did not establish U.S. claims to Florida or give the U.S. access to the Pacific.<br /><br />## Step 5<br />The Webster-Ashburton Treaty of 1842 settled several border disputes between the United States and the United Kingdom, including those in Maine and the Great Lakes. However, it did not establish U.S. claims to Florida or give the U.S. access to the Pacific.
