QUES: The National Archives Building, known informally as Archives I, located north of the National Mall on Constitution Avenue in Washington, D.C., opened as its original headquarters in 1935. It holds the original copies of the three main formative documents of the United States and its government: the Declaration of Independence, the Constitution, and the Bill of Rights. It also hosts a copy of the 1297 Magna Carta confirmed by Edward I. These are displayed to the public in the main chamber of the National Archives, which is called the Rotunda for the Charters of Freedom. The National Archives Building also exhibits other important American historical documents such as the Louisiana Purchase Treaty, the Emancipation Proclamation, and collections of photography and other historically and culturally significant American artifacts.

In what year was the Emancipation Proclamation written?
What is the answer?
ANS: unanswerable
QUES: As of September 2012, fifty-six species have been delisted; twenty-eight due to recovery, ten due to extinction (seven of which are believed to have been extinct prior to being listed), ten due to changes in taxonomic classification practices, six due to discovery of new populations, one due to an error in the listing rule, and one due to an amendment to the Endangered Species Act specifically requiring the species delisting. Twenty-five others have been down listed from "endangered" to "threatened" status.

How many species were delisted due to discoveries of new populations?
What is the answer?
ANS: six
QUES: Examples of energy transformation include generating electric energy from heat energy via a steam turbine, or lifting an object against gravity using electrical energy driving a crane motor. Lifting against gravity performs mechanical work on the object and stores gravitational potential energy in the object. If the object falls to the ground, gravity does mechanical work on the object which transforms the potential energy in the gravitational field to the kinetic energy released as heat on impact with the ground. Our Sun transforms nuclear potential energy to other forms of energy; its total mass does not decrease due to that in itself (since it still contains the same total energy even if in different forms), but its mass does decrease when the energy escapes out to its surroundings, largely as radiant energy.

What is another example of solar transformation?
