Question: What year was Georgia Southern founded? Passage:The Georgia Southern Eagles football program represents Georgia Southern University in football as part of the Sun Belt Conference under head coach Chad Lunsford. The Eagles have won six FCS (I-AA) national championships and have produced two Walter Payton Award winners. The Eagles first continuously fielded a football team in 1924; however, play was suspended for World War II and revived in 1981. The Eagles competed as an FCS independent from 1984 until 1992 as the Eagles' main conference at the time, the Trans America Athletic Conference (now known as the Atlantic Sun Conference), did not sponsor football, and as a member of the Southern Conference from 1993 until 2013, winning 10 SoCon championships. Georgia Southern joined the Sun Belt Conference upon transitioning to the FBS level in 2014. The Eagles won the Sun Belt Conference championship outright in its first year as an FBS member. Georgia Southern's main Sun Belt rival is Appalachian State.

Question: How much more of the vote percentage did Trump win than McCain? Passage:As part of Middle Tennessee, Grundy County has historically been one of the strongest Democratic counties in the state. It voted Democratic in every presidential election from 1912 to 2004, except for in 1968 (when segregationist George Wallace won the county), and 1972 when many traditional Democratic voters around the nation rejected the perceived radical liberal George McGovern in favor of incumbent Republican Richard Nixon. However, like most of the rural south, Grundy County has shifted towards the Republican Party in recent years, but was one of the last counties in Tennessee to make the switch to the party. The last Democratic Presidential candidate to win Grundy County was John Kerry in 2004, who won 18 out of Tennessee's 95 counties, whereas Al Gore won 36 in 2000. Grundy County was also won by Democratic U.S senate candidates Bob Clement in 2002 and Harold Ford Jr. in 2006, both of whom lost. Republican Presidential nominee John McCain won the county by nearly 13% in 2008, becoming the first Republican Presidential candidate to win Grundy County since Nixon won it 36 years earlier, and by 2016, Grundy County had taken a major shift toward the GOP, when Republican Donald Trump received 76% of the vote, a figure closer to what is usually seen in historically Republican East Tennessee counties.
