Text: The groundhog (Marmota monax), also known as a woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. It was first scientifically described by Carl Linnaeus in 1758. The groundhog is also referred to as a chuck, wood-shock, groundpig, whistlepig, whistler, thickwood badger, Canada marmot, monax, moonack, weenusk, red monk and, among French Canadians in eastern Canada, siffleux. The name ''thickwood badger'' was given in the Northwest to distinguish the animal from the prairie badger. Monax was a Native American name of the woodchuck, which meant ''the digger''. Young groundhogs may be called chucklings. Other marmots, such as the yellow-bellied and hoary marmots, live in rocky and mountainous areas, but the groundhog is a lowland creature. It is found through much of the eastern United States across Canada and into Alaska

Text: The White House Reconstruction, also known as the Truman Reconstruction, was a comprehensive dismantling and rebuilding of the interior of the White House between 1949-1952. A century-and-a-half of wartime destruction and rebuilding, hurried renovations, additions of new services, technologies, an added Third Floor, and inadequate foundations brought the Executive Residence portion of the White House Complex to near-imminent collapse. In 1948 architectural and engineering investigations deemed it unsafe for occupancy and President Harry S. Truman, his family, and the entire residence staff were relocated across the street. For over three years the White House was gutted, expanded, and rebuilt. The scope, costs, and historical authenticity of the work were controversial, with the reconstruction being called both structurally essential, and a disaster.

Question: has the white house changed or been added onto since it was first built?
