Task: Question Generation
Input (English): The U.S. military has proposed building a new aircraft carrier berth on Guam and moving 8,600 Marines, and 9,000 of their dependents, to Guam from Okinawa, Japan. Including the required construction workers, this buildup would increase Guam's population by 45%. In a February 2010 letter, the United States Environmental Protection Agency sharply criticized these plans because of a water shortfall, sewage problems and the impact on coral reefs. By 2012, these plans had been cut to only have a maximum of 4,800 Marines stationed on the island, two thirds of which would be there on a rotational basis without their dependents.
Output (English): How many Marines would the United States move to Guam?
