[Q]: Question: What year did the Steelers appear in their first Super Bowl? Passage:The Pittsburgh Steelers compete in the National Football League (NFL) as a member club of the American Football Conference (AFC) North division. Founded in 1933, the Steelers are the oldest franchise in the AFC; seven franchises in the National Football Conference (NFC) have longer tenures in the NFL. The team struggled to be competitive in its early history, posting winning records in just 8 of its first 39 seasons. Since the AFL–NFL merger in 1970, however, it has appeared in eight Super Bowls and one of only two teams, along with the New England Patriots have won the Super Bowl six times. The six championships place the Steelers fourth in the league in terms of total championships (including those prior to the first Super Bowl), trailing only the Green Bay Packers (13 championships), the Chicago Bears (9) and the New York Giants (8). The club's 15 AFC Championship Game appearances are second all-time, behind the Patriots (16). In addition, they have hosted the second-most conference championship games (11) than any franchise in either conference, and are tied for second with the Dallas Cowboys and Denver Broncos with eight Super Bowl appearances; the Patriots currently hold the record of eleven appearances, as of 2019.

[Q]: Question: How many battles had Oswald Watt commanded by the year Holden joined the Australian Imperial Force? Passage:Holden enlisted in the Australian Imperial Force on 26 May 1915, and was posted to the 4th Light Horse Brigade as a private. He departed for Egypt aboard the transport A29 Suevic on 13 June. Serving as a driver first in the Middle East and then on the Western Front, his mechanical ability and sense of adventure led him to volunteer for the Australian Flying Corps (AFC) in December 1916. After qualifying as a pilot in England, he was commissioned a lieutenant and posted to No. 2 Squadron. Commanded by Major Oswald Watt, No. 2 Squadron's personnel included many former Lighthorsemen, as well as mechanics from the AFC's first combat formation, the Mesopotamian Half Flight. The force trained extensively in England commencing in January 1917, before deploying to the Western Front that September. Holden was involved in the AFC's first day of combat in France; just after noon on 2 October, in the vicinity of Saint-Quentin, he and his wingman engaged a German two-seater that managed to escape.

[Q]: Question: Who is the oldest judge that formed the majority opinion on January 21, 2019? Passage:The policy change faced legal challenges. Following a challenge in the U.S. District Court for the District of Columbia, on October 30, 2017, Judge Colleen Kollar-Kotelly blocked enforcement of the ban, writing that as far as could be seen, "all of the reasons proffered by the president for excluding transgender individuals from the military in this case were not merely unsupported, but were actually contradicted by the studies, conclusions and judgment of the military itself". In March 2018, Trump announced a new policy on transgender service members, namely a ban on those with a diagnosis of gender dysphoria, which would effectively be a ban on most transgender service members. The new policy was challenged in the U.S. District Court for the Western District of Washington. On April 13, 2018 Judge Marsha J. Pechman blocked enforcement of the policy, ruling that the administration's updated policy essentially repeated the same issues as its predecessor order from 2017, and that transgender service members (and transgender individuals as a class) were a protected class entitled to strict scrutiny of adverse laws (or at worst, a quasi-suspect class), and ordered that matter continue to a full trial hearing on the legality of the proposed policy. On January 21, 2019, the Supreme Court — with Chief Justice John Roberts and Justices Samuel Alito, Neil Gorsuch, Brett Kavanaugh and Clarence Thomas forming the majority for the 5-4 opinion — allowed Trump's policy to go into effect while challenges in lower courts are adjudicated. On March 12, 2019, acting Deputy Defense Secretary David Norquist signed a directive to allow Trump's policy to take effect in 30 days.
