Input: Consider Input: Question: What other countries did Loring fight with while he supported the United nations command ground troops? Passage:In July 1952, Loring transferred to the 36th Fighter-Bomber Squadron full-time, where he served as operations officer. In this role he returned to combat duty, this time as a jet aircraft fighter pilot operating the F-80 Shooting Star. Missions for this unit primarily concerned close air support, air strikes and interdiction missions supporting United Nations Command ground troops in the country. In this role, Loring's unit primarily fought North Korean and Chinese ground targets. By November 22, 1952, Loring had completed 50 combat missions. At that time the ground battle in Korea had developed into a stalemate, with the two sides firmly entrenched along the 38th Parallel. Throughout November, the UN forces had been launching Operation Showdown against two targets: Triangle Hill and Sniper Ridge, northwest of Kunwha, north of the 38th Parallel. During the battle, the Chinese managed to amass 133 large caliber guns, 24 BM-13 rocket launchers and 47 anti-aircraft guns in the largest Chinese artillery operation during the Korean War, and it posed a serious threat to ground troops of the ROK 2nd Infantry Division operating in the area. The artillery was heavily guarded, forcing the UN forces to use airpower to combat them.

Input: Consider Input: Question: How many days did one of the largest battles in medieval Europe last? Passage:The Polish–Lithuanian–Teutonic War or Great War occurred between 1409 and 1411, pitting the allied Kingdom of Poland and Grand Duchy of Lithuania against the Teutonic Knights. Inspired by the local Samogitian uprising, the war began by Teutonic invasion of Poland in August 1409. As neither side was ready for a full-scale war, Wenceslaus IV of Bohemia brokered a nine-month truce. After the truce expired in June 1410, the military-religious monks were decisively defeated in the Battle of Grunwald (Tannenberg), one of the largest battles in medieval Europe. Most of the Teutonic leadership was killed or taken prisoner. While defeated, the Teutonic Knights withstood the siege on their capital in Marienburg (Malbork) and suffered only minimal territorial losses in the Peace of Thorn (1411). Territorial disputes lasted until the Peace of Melno of 1422. However, the Knights never recovered their former power and the financial burden of war reparations caused internal conflicts and economic decline in their lands. The war shifted the balance of power in Central Europe and marked the rise of the Polish–Lithuanian union as the dominant power in the region.

Input: Consider Input: Question: Which of the actors as Thomas Edison and George Westinghouse as of September 24, 2015 is older? Passage:Michael Mitnick began writing the script for The Current War in 2008, basing it on the real life "war of the currents" AC/DC conflict between Edison and Westinghouse. The screenplay is the conclusive result of sixty drafts, a ten-year writing process, first as a musical and finally as a film. In 2011 Mitnick's screenplay made the Black List, an industry survey of "most liked" screenplays not yet produced. On May 3, 2012, it was reported that Timur Bekmambetov's company, Bazelevs, had acquired the rights to Mitnick's screenplay. Bekmambetov was set to direct. On March 31, 2014, it was reported that Ben Stiller was in negotiations to direct the film. As of September 24, 2015, Benedict Cumberbatch and Jake Gyllenhaal were in talks to play Thomas Edison and George Westinghouse, respectively, with Alfonso Gomez-Rejon (Me and Earl and the Dying Girl) eyed to direct the film. Sacha Baron Cohen was also briefly linked to the role of Edison. On September 29, 2016, Michael Shannon was cast as Westinghouse, and on October 4, Nicholas Hoult was cast as Nikola Tesla. In November 2016, Katherine Waterston and Tom Holland joined the cast. The following month, Tuppence Middleton and Matthew Macfadyen were cast.
