Input: Question: In which country did Macmillan earned his bachelor degree? Passage 1:The New York Giants visited the Washington Redskins on September 11, 2011, the first Sunday of the regular season, to commemorate the tenth anniversary of the September 11 attacks in which Washington, D.C. and New York City were both targeted, as well as the first such anniversary since the killing of Osama bin Laden in May. Due to the proximity of Baltimore with Washington as well as the proximity of Pittsburgh with the site where United Airlines Flight 93 crashed, the Pittsburgh Steelers visited the archrival Ravens at M&T Bank Stadium in Baltimore. It marked the first time the two teams played in a season-opening game since 2003, as their heated rivalry usually prompts their games to be scheduled later in the season. There had been some speculation that the Giants and their same-city rival, the New York Jets, could have played each other that day since the two were scheduled to play each other in 2011; the Jets were the designated home team at MetLife Stadium in the matchup which had been predetermined due to the NFL's scheduling formula. However, the Jets instead hosted the Dallas Cowboys.
