Example Input: Archaeologists say they have unearthed the oldest human footprints ever found in North America. The impressions were discovered buried at a shoreline at an archaeological dig site on Calvert Island, British Columbia in Canada. Charcoal in the prints has been radiocarbon dated, giving them an age of 13,200 years old. The finding was made by the Hakai Institute and the University of Victoria, both in British Columbia. Archaeologists Dr Daryl Fedje and Dr Duncan McLaren excavated an area below the high tide line, and found dozens of human footprints that had remained intact in clay. An ancient skeleton found nearly 20 years ago in a river in Washington is related to Native Americans, says a DNA study that could help resolve a long-running dispute over its ancestry.Human footprints were found preserved on Calvert Island in CanadaThey were radiocarbon dated to a remarkable 13,200 years oldIf confirmed they would be the oldest human footprints in North AmericaDiscovery also suggests people once migrated down the coast 
 Question:'There's no way to get to _ other than watercraft, and that applies to 13,000 years ago as it does today,' Dr McLaren said.
Example Output: Calvert Island

Example Input: Washington (CNN) Donald Trump's top budget adviser defended the sweeping cuts proposed to social, foreign aid and environmental programs in the President's budget on Tuesday, arguing that the White House could no longer ask taxpayers for money to fund programs they believe to be inefficient. Economists and Democrats have already panned the budget as a document that benefits the wealthy and cuts services from the poor. Mick Mulvaney, Trump's budget chief, rejected that idea on Tuesday. "We are no longer going to measure compassion by the number of programs or the number of people on those programs, but the number of people we help get off of those programs," he said, arguing that it is actually compassionate to cut government spending on inefficient programs.Economists and Democrats have already panned the budget as a document that benefits the wealthyThe budget assumes that the American economy will begin growing at 3% each year
