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.
The White House was designed by James Hoban, who was born in Ireland and had studied in Dublin. Historians believe that James Hoban based his plan on the Leinster House, the Georgian style home of the Dukes of Leinster in Ireland. Leinster House is now the seat of the Irish Parliament.
