Example Input: Tuesday, September 11, 2001, dawned temperate and nearly cloudless in the eastern United States. Millions of men and women readied themselves for work. Some made their way to the Twin Towers, the signature structures of the World Trade Center complex in New York City. Others went to Arlington, Virginia, to the Pentagon. Across the Potomac River, the United States Congress was back in session. At the other end of Pennsylvania Avenue, people began to line up for a White House tour. In Sarasota, Florida, President George W. Bush went for an early morning run. For those heading to an airport, weather conditions could not have been better for a safe and pleasant journey. Among the travelers were Mohamed Atta and Abdul Aziz al Omari, who arrived at the airport in Portland, Maine. Boston: American 11 and United 175. Atta and Omari boarded a 6:00 A.M. flight from Portland to Boston's Logan International Airport. When he checked in for his flight to Boston, Atta was selected by a computerized prescreening system known as CAPPS (Computer Assisted Passenger Prescreening System), created to identify passengers who should be subject to special security measures. Under security rules in place at the time, the only consequence of Atta's selection by CAPPS was that his checked bags were held off the plane until it was confirmed that he had boarded the aircraft. This did not hinder Atta's plans. Atta and Omari arrived in Boston at 6:45. Seven minutes later, Atta apparently took a call from Marwan al Shehhi, a longtime colleague who was at another terminal at Logan Airport. They spoke for three minutes. It would be their final conversation. <sep>At what time did Atta end his call with Marwan Al Shehhi?<sep>6:07

Example Input: Washington The Iraqi government has agreed to let U.S. Rep. Tony Hall visit the country next week to assess a humanitarian crisis that has festered since the Gulf War of 1990, Hall's office said Monday. The Dayton Democrat, who has traveled to other crisis points including Sierra Leone and North Korea, will spend three days visiting hospitals and other facilities to seek understanding why aid has been ineffective in stemming malnourishment and other medical problems. Iraq has been under economic sanctions since the war ended, which some say have thwarted the country's ability to recover from the devastation of the bombing campaign. The Persian Gulf War destroyed much of the country's medical infrastructure, according to a report by the World Health Organization. In 1996 the WHO found that much of the population existed in a state of ``semi-starvation.'' Hall will be only the second member of Congress to travel in Iraq since the war, according to Hall's office. The last visitor was then-U.S. Rep. Bill Richardson of New Mexico, who went to help a pair of U.S. oilmen in diplomatic trouble. Hall flies to Amman, Jordan, on Friday, where he'll spend the night before driving to Iraq. Flights are not permitted into Iraq. Hall is to return to Washington on April 22. Story Filed By Cox Newspapers <sep>Why is U.S. Rep. Tony Hall visiting Iraq?<sep>To seek understanding why aid has been ineffective in stemming malnourishment and other medical problems
