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.
A circular pool with fountain is centered on the north portico of the White House. Visiting heads of state enter the White House grounds, and are officially welcomed here prior to a state dinner. Public tours, which begin on East Executive Drive, exit through the North Portico, and visitors exit from the northeast gate.
