Input: Consider Input: Question: What team did Nick Foles play for when Minshew made his debut? Passage:On September 8, 2019, Minshew made his NFL debut against the Kansas City Chiefs when starter Nick Foles was taken out of the game due to a shoulder injury. He completed 22 of 25 passes for 275 yards, two touchdowns and an interception in the 40–26 loss. Minshew's pass completion percentage of 88% is the highest of any player making his debut in NFL history (minimum 15 pass attempts, since at least 1950), and also the highest single-game pass completion percentage in Jaguars history. Minshew was named the starter going forward after it was revealed that Foles had suffered a broken clavicle. During Week 2 against the Houston Texans, Minshew finished with 213 passing yards and a touchdown along with 56 rushing yards as the Jaguars lost 13–12. In Week 3, against the Tennessee Titans on Thursday Night Football, he earned his first victory as a professional. He passed for 204 yards and two touchdowns in the 20–7 victory. In Week 4, against the Denver Broncos, he passed for 213 yards and two touchdowns in the 26–24 victory. Late in the game, he engineered a drive that helped set up the Jaguars' game-winning field goal by Josh Lambo. During Week 5 against the Carolina Panthers, Minshew finished with 374 passing yards and two touchdowns as the Jaguars lost 27–34. After a Week 6 loss to the New Orleans Saints and a Week 7 victory over the Cincinnati Bengals, he had 279 passing yards and three passing touchdowns in a 29–15 victory over the New York Jets. During Week 9 against the Texans at Wembley Stadium, Minshew finished with 309 passing yards and 2 interceptions as the Jaguars lost 3–26. Days later, it was announced that Minshew would resume the backup role after Foles returned from his collar bone injury.

Input: Consider Input: Question: How old was Ibrahim Pasha the year the conquest of the Sudan began? Passage:The reign of Farouk was characterized by ever increasing nationalist discontent over the British occupation, royal corruption and incompetence, and the disastrous 1948 Arab–Israeli War. All these factors served to terminally undermine Farouk's position and paved the way for the revolution of 1952. Farouk was forced to abdicate in favor of his infant son Ahmed-Fuad who became King Fuad II, while administration of the country passed to the Free Officers Movement under Muhammad Naguib and Gamal Abdel Nasser. The infant king's reign lasted less than a year and on June 18, 1953, the revolutionaries abolished the monarchy and declared Egypt a republic, ending a century and a half of the Muhammad Ali Dynasty's rule. Emerging victorious from a war-triangle (Ottomans, Mamluks, and his loyal troops), Mehmed Ali made good use of Albanian irregulars services as mercenaries and troops to bolster his reign. Albanian mercenaries, or Arnauts, presented the backbone of Ali's army and were known as elite and undisciplined soldiers of the Ottoman Empire armies. With the rise of Muhammad Ali in power, many of them would settle in Egypt and serve there. By 1815, the number of Albanian military was over 7000. Albanian troops partook in the war against the Wahhabi movement in Arabia (1811–18) and in the conquest of the Sudan (1820–24). The number of Albanian troops would diminish in 1823, when Ibrahim Pasha, Ali's son, would join the Ottoman armies in the Greek War of Independence along with circa 17,000 men, many of them Albanians. Ali's dynasty would continue to rule Egypt until 1952.

After one year at Munich, he returned to Tübingen to be able to study spectroscopy with Friedrich Paschen. While still a student in 1914, Meissner was able to prove the existence of oxygen lines in the solar spectrum. He was awarded his doctorate in 1915, on a thesis with the title Interferometrische Wellenlängenbestimmung im infraroten Spektralbereich. In 1916 he became an assistant to Edgar Meyer at the University of Zurich, under whom he completed his Habilitation, in 1918, with the Habilitationsschrift title Untersuchungen des Neonspektrums. The following year, he married the Polish physicist Doctor Janka Kohn.
