To review, there are three concepts to determine before you begin writing your essay: the tone, the audience and the purpose. The tone is the attitude of the writer. Two factors that greatly affect the tone are audience and purpose. The audience of an essay is anyone who might read it.
The White House is not in a state. It is located in Washington, D.C. The District of Columbia is a federal district that Congress established in the late 1700s with land Virginia and  Maryland donated for the purpose of serving as home to the nation's capital.
Construction began when the first cornerstone was laid in October of 1792. Although President Washington oversaw the construction of the house, he never lived in it. It was not until 1800, when the White House was nearly completed, that its first residents, President John Adams and his wife, Abigail, moved in. Since that time, each President has made his own changes and additions. The White House is, after all, the Presidents private home.
