[EX Q]: Question: How old was Alexander's wife when they got married? Passage 1:The Irish government under outgoing Taoiseach Enda Kenny expressed concerns that a parliamentary deal between a British government and the DUP could put the Northern Ireland peace process at risk, a view also expressed by Sinn Féin politicians Gerry Adams and Gerry Kelly, Labour MP Yvette Cooper and former Downing Street Director of Communications Alastair Campbell. This opinion was, however, rejected by the Conservative leadership and former Secretary of State for Northern Ireland, Theresa Villiers, as well as by former Labour minister Caroline Flint who suggested that Gordon Brown may have sought an agreement with the DUP in 2010. The Conservative peer and former UUP First Minister of Northern Ireland, David Trimble, described claims that an agreement would put the peace process at risk as "scaremongering". On 13 June former Conservative Prime Minister John Major publicly urged May to govern without DUP support and not pursue a deal, on the grounds that an agreement could "damage" the "fragile" Northern Ireland peace process, suggesting the government must remain 'impartial'. Major himself had an agreement with the Unionist MPs of the UUP when in power and during peace negotiations in Northern Ireland, though not with the more hardline and socially-conservative DUP. On 15 June Sinn Féin's Gerry Adams met with Theresa May, telling her that he thought she was in breach of the Good Friday Agreement. This has been disputed by one of the UUP's negotiators for the Belfast Agreement.
 Passage 2:He testified as an expert witness about Russian interference in the 2016 United States elections, in a March 30, 2017 hearing before the United States Senate Select Committee on Intelligence. His testimony before the Senate Intelligence Committee was well received, and made multiple headlines. Slate referred to him in a headline as: "Clint Watts, Testifier Extraordinaire", and "The star of March’s Senate Intelligence Committee hearing". CNN profiled him after the testimony in a piece "Russia investigation: Who is Clint Watts", where it was noted he gained knowledge in the field of Russian cyber hacking methods, after himself being a target in 2015 following his "Trolling for Trump" article; the FBI notified the Foreign Policy Research Institute of the attack. Salon compared his testimony "follow the trail of dead Russians" to John Dean's statement about "a cancer on the presidency". This phrase in testimony by Watts was highlighted by the media, including CBS News, The American Interest, and The Oregonian. U.S. Senator Ron Wyden found the comment important to his investigation. Mark Shields of PBS NewsHour found his testimony "compelling", and CNN called it "blistering". Jennifer Rubin wrote for The Washington Post that his testimony "laid out the most comprehensive look at the array of tools Russia used to influence our election". After his testimony, he appeared on NBC's Meet the Press and explained ways the U.S. can better respond to cyberwarfare.
 Passage 3:Ancient historians, as well as modern ones, have also written on Alexander's marriage to Roxana the beautiful [Persian]n woman. Robin Lane Fox writes, "Roxana was said by contemporaries to be the most beautiful lady in all Asia. She deserved her name of Roshanak, meaning 'little star', (probably rokhshana or roshana which means light and illuminating) in Persian. Marriage to a local noble's family made sound political sense, but contemporaries implied that Alexander, aged 28, also lost his heart. A wedding-feast for the two of them was arranged high on one of the Persian rocks. Alexander and his bride shared a loaf of bread, a custom still observed in Turkestan. Characteristically, Alexander sliced it with his sword. Ulrich Wilcken writes, "The fairest prize that fell to him was Roxana, the daughter of Oxyartes, in the first bloom of youth, and in the judgment of Alexander's companions, next to Stateira the wife of Darius, the most beautiful woman that they had seen in Asia. Alexander fell passionately in love with her and determined to raise her to the position of his consort."

[EX Q]: Question: Who was in charge of Messerschmitt when the Heinkel He 176 first flew? Passage 1:At the same time that Walter was developing submarine engines, he was also applying his ideas to rocketry. The high-pressure gas mixture created by the rapid decomposition of hydrogen peroxide could not only be used in a turbine, but if simply directed out of a nozzle, created considerable thrust. Wernher von Braun's rocketry team working at Peenemünde expressed interest in Walter's ideas, and in 1936 began a programme of installing Walter rockets into aircraft. The experimental results obtained by von Braun created interest among Germany's aircraft manufacturers, including Heinkel and Messerschmitt, and in 1939, the Heinkel He 176 became the first aircraft to fly on liquid-fuelled rocket power alone. This type of engine went on to become the cornerstone of the Messerschmitt Me 163 rocket-powered fighter, when married to Alexander Lippisch's revolutionary airframe design. Throughout the course of World War II, Walter's aircraft engines became increasingly powerful and refined. The original design of simply decomposing hydrogen peroxide was soon changed to its use as an oxidizer (much like dinitrogen tetroxide would be used later) when combined with a hydrazine/methanol true rocket fuel designated C-Stoff, into the hot, high-pressure gases, and in later, never-deployed developments, a second, 400 kg (880 lb) thrust "cruising" combustion chamber, nicknamed a Marschofen, was added below the main chamber to allow for more precise control of the engine. Versions of this engine were intended to power a variety of aircraft design proposals and missile projects and was also licence-built in Japan (see HWK 109-509).
 Passage 2:In 2012, Hudson Mohawke began a series of collaborations with Kanye West, resulting in production credits on the GOOD Music label album Cruel Summer.

TNGHT announced their hiatus on 27 December 2013.

In 2015, he released his second studio album, Lantern. In 2016, he collaborated with singer Anohni on her 2016 album Hopelessness. Mohawke announced on 26 October 2016 via Twitter that he was creating the original soundtrack for the 2016 video game Watch Dogs 2 titled "Ded Sec" and that Warp Records would release it on 11 November 2016.
