Input: Consider Input: Question: Who founded the institution where Powderly served as a professor in the Visual Communication Design Department? Passage 1:In 2005, Powderly became a Research and Development Fellow at Eyebeam where he began collaborating with Evan Roth. Working as the Graffiti Research Lab, Roth and Powderly developed open source tools for graffiti writers and activists, such as LED Throwies and L.A.S.E.R. Tag. Together, they also founded the Free Art and Technology Lab (F.A.T. Lab). Most recently, Powderly has won awards for his work on the EyeWriter project, including the 2009 Design of the Year in Interactive Art from the Design Museum, London, the 2010 Prix Ars Electronica, the 2010 FutureEverything Award and featured on NPR and TED. Several of Powderly' works are in the permanent collection of the Museum of Modern Art. Powderly was a professor at Hongik University in the Visual Communication Design Department in Seoul, South Korea, before moving to Fort Lauderdale, Florida, to work for the augmented reality company Magic Leap.
 Passage 2:On March 11, 1996, the Montreal Canadiens played their last game at the Montreal Forum, defeating the Dallas Stars 4-1. The game was televised on TSN and TQS in Canada, and on ESPN2 in the United States. The Stars' Guy Carbonneau, who had captained the Canadiens from 1989 to 1994 (including their 1993 Cup win), took the ceremonial opening faceoff. After the game, many previous hockey greats were presented to the crowd, most notably Maurice Richard (said to be the Canadiens' most beloved player of all time), who received a sixteen-minute standing ovation from the crowd as he broke down in tears. A symbolic torch—representative of a line quoted from the poem In Flanders Fields, "To you from failing hands we throw the torch; be yours to hold it high," displayed in the Forum's home dressing room—was carried by Emile Bouchard out of the Canadiens dressing room to the playing surface. The flaming torch was passed on to each of the former Canadiens captains (Jean Beliveau, Yvan Cournoyer, Henri Richard, Serge Savard, Bob Gainey, and Carbonneau), and finally to the then-current captain Pierre Turgeon. The next day, a parade was organized in which the torch was carried down the route to the Molson Centre (which has since been renamed the Bell Centre). Their first game at the new venue was against the New York Rangers, a game which the Canadiens won.
 Passage 3:A new pre-dreadnought battleship, , was ordered under the new construction program in 1889. The advent of the 1891 Chilean Civil War saw a breach between the two branches of the Chilean Armed forces, while the bulk of navy sided the congress side the majority of the Chilean Army remained loyal to José Manuel Balmaceda. When the majority of the national congress broke relations with the government Jorge Montt took control of the fleet at Valparaíso and with notable politicians, like Ramón Barros Luco, on board the fleet sailed north to the nitrate-rich Tarapacá area which Chile had seized from Peru ten years earlier. Tarapacá was by that time Chile's richest region in terms of natural resources and was without the fleet practically out of reach for the Chilean Army. From here the navy organized an army made of nitrate miners which they armed and trained to face the 40,000-men strong Army of Chile. In August 1891 the new army was disembarked in Quintero and defeated the Chilean Army at the Battle of Concón and the Battle of Placilla before the presidential faction disbanded and the congressional side took power. On the elections of October 1891 Jorge Montt was elected president.

Input: Consider Input: Question: What is the age difference between the two men who Trump asked Zelensky to launch investigations into? Passage 1:A July 25, 2019 telephone call between Trump and Ukraine president Volodymyr Zelensky led in September to a whistleblower complaint and an impeachment inquiry against Trump. Two weeks after the inquiry was launched, Trump claimed in a conference call with Congressional Republican leaders that he had only made the telephone call at Perry's urging. Perry's spokesperson said that Perry had suggested Trump discuss energy security with Zelensky, but energy was not mentioned in the publicly released memo about the conversations, which instead focused on Trump asking Zelensky to launch investigations into Joe Biden, Hunter Biden, Crowdstrike, and the 2016 U.S. presidential election. Per Trump's direction earlier this year, Perry spoke with Rudy Giuliani about Ukraine, which Mick Mulvaney confirmed. Perry denied ever mentioning the Bidens in his discussions with Trump or Ukrainian officials. Mulvaney had put Gordon Sondland, Kurt Volker, and Perry in charge of managing the Ukraine–United States relations instead of diplomats at the National Security Council and the US Department of State.

Passage 1:From 1931, Hermes studied mathematics, physics, chemistry, biology and philosophy at the University of Freiburg.

In 1949 he became a Professor at the University of Münster, where he turned back to the subject of mathematical logic.
 Passage 2:Between 1980 and 1988, the conflict intensified as the Iran–Iraq War commenced. One of the groups targeted in particular by Iraqi authorities were the Feyli Kurds, a community of Shi'ite Kurds settled in the southern area of the Zagros Mountains near Iraq's border with Iran. Saddam Hussein considered the group as 'Iranians' and began a campaign to drive the settlers out of the area as a part of his 'Arabization' policy in 1980., Saddam Hussein was severely critical of the Kurdistan Democratic Party (KDP) as they aligned forces with Iran in the conflict. In 1983, to avenge this liaison, he ordered the Army to abduct as many as 8,000 men and boys from Erbil province, where the clan of Barzani Kurds was based. Massoud Barzani, the leader of the clan and the KDP, himself lost 37 members of his family to the Iraqi troops. They were reported to having been sent to Nugra Salman prison in the southern deserts of Iraq, where they were tortured. Subsequently, the remains of 512 Barzani men were discovered in a mass grave. On March 16, 1988, Iraqi troops began shelling the Kurdish town of Halabja, in retaliation for an attack on Iraqi positions carried out by Iranian Revolutionary Guards and the aligned Peshmerga fighters. Subsequently, the town was attacked with a mix of chemical substances such as VX (nerve agent), sarin and mustard gas (see Halabja chemical attack). Over 5,000 people are believed to have been killed in the attack, which was considered to be a part of the Al-Anfal Campaign, directed against Kurds by the government under the command of Ali Hassan al-Majid, head of the Northern Bureau of the Ba'ath Party.
 Passage 3:Construction of the nuclear submarine Ekaterinburg (K-84) began at the Northern Machinebuilding Enterprise (Sevmash) in Severodvinsk on 17 February 1982, before being commissioned into the Soviet Navy on 30 December 1985. She was the second of the seven-boat Project 667BDRM Delfin class, which was developed at the Rubin Design Bureau in September 1975. A ballistic missile submarine, she was designed primarily to carry up to 16 R-29RM Shtil (NATO designation: SS-N-23 Skiff) SLBM for use against military and industrial facilities in the case of a nuclear war. Each Shtil missile carries ten 100 kt multiple independently targeted reentry vehicles, and has a circular error probable of . She is also equipped with RPK-7 Veter (NATO designation: SS-N-16 Stallion) anti-ship missiles for use against large surface vessels, and self-defense torpedoes.
