Question: Passage: Mammy Two Shoes is preparing a fancy dinner, with both Tom and Jerry observing. Jerry starts eating the cracker spread, but Tom knocks Jerry out by whacking him with a spoon and calls Toots, his love interest, to invite her to dinner. Jerry is forced to perform menial duties for the cats, such as carrying food and blowing on Tom's soup. Annoyed, Jerry drinks the soup and spits it into Tom's face, causing Tom to put the spoon Jerry is standing on over a burning candle to make him hop on both feet and yelp in pain.
As Toots offers Tom bread, Jerry sandwiches Tom's tail between it. Unaware, Tom pours ketchup onto it and bites it, causing him to leap up in pain. Tom is then unaware again, trying to stay cool for his date, as Jerry puts a pineapple slice, cream and cherry onto it, and Tom leaps up after biting it again. Tom grabs Jerry and twists his tail into a champagne-cork opener to make two drinks, launching Jerry into a glass of water.
Tom then tries to hug and kiss his girlfriend, but Toots impressively dodges each attempt. When Tom finally hugs Toots, she takes out a "wolf pacifier" (a mallet) and wallops him with it. As Jerry mocks Tom, Tom puts a cigar into Jerry's mouth, whacks him and lights a cigar onto him, causing Jerry to launch a pie into Tom's face. Tom throws a pie in return, but Jerry ducks and the pie hits Toots, effectively ending the relationship between the two cats. 
Question: What are the names of the cats who had a relationship?

Answer: Jerry.


Question: Passage: In September 1930 Heseltine moved with Barbara Peache into a basement flat at 12a Tite Street in Chelsea. With no fresh creative inspiration, he worked in the British Museum to transcribe the music of English composer Cipriani Potter, and made a solo version of "Bethlehem Down" with organ accompaniment. On the evening of 16 December Heseltine met with Van Dieren and his wife for a drink and invited them home afterwards. According to Van Dieren, the visitors left at about 12:15 a.m. Neighbours later reported sounds of movement and of a piano in the early morning. When Peache, who had been away, returned early on 17 December, she found the doors and windows bolted, and smelled coal gas. The police broke into the flat and found Heseltine unconscious; he was declared dead shortly afterwards, apparently as the result of coal gas poisoning.An inquest was held on 22 December; the jury could not determine whether the death was accidental or suicide and an open verdict was returned. Most commentators have considered suicide the more likely cause; Heseltine's close friend Lionel Jellinek and Peache both recalled that he had previously threatened to take his life by gas and the outline of a new will was found among the papers in the flat. Much later, Nigel Heseltine introduced a new theory—that his father had been murdered by Van Dieren, the sole beneficiary of Heseltine's 1920 will, which stood to be revoked by the new one. This theory is not considered tenable by most commentators. The suicide theory is supported (arguably), by the (supposed, accepted) fact that Heseltine/Warlock had put his young cat outside the room before he had turned on the lethal gas.Philip Heseltine was buried alongside his father at Godalming cemetery on 20 December 1930. In late February 1931, a memorial concert of his music was held at the Wigmore Hall; a second such concert took place in the following December.In 2011 the art critic Brian Sewell published his memoirs, in which he claimed that he was Heseltine's illegitimate son, born in July 1931 seven months after the composer's death. Sewell's mother, unnamed, was an intermittent girlfriend, a Roman Catholic  who refused Heseltine's offer to pay for an abortion and subsequently blamed herself for his death. Sewell was unaware of his father's identity until 1986. 
Question: What is the last name of the person whose death could not be determined to be accident or suicide?

Answer: Heseltine.


Question: Passage: Following the end of the Second World War, the East German side of the border was guarded initially by the Border Troops (Pogranichnyie Voiska) of the Soviet NKVD (later the KGB). They were supplemented from 1946 by a locally recruited paramilitary force, the German Border Police (Deutsche Grenzpolizei or DGP), before the Soviets handed over full control of the border to the East Germans in 1955/56. In 1961, the DGP was converted into a military force within the National People's Army (Nationale Volksarmee, NVA). The newly renamed Border Troops of the GDR (Grenztruppen der DDR, commonly nicknamed the Grenzer) came under the NVA's Border Command or Grenzkommando. They were responsible for securing and defending the borders with West Germany, Czechoslovakia, Poland, the Baltic Sea and West Berlin. At their peak, the Grenztruppen had up to 50,000 personnel.Around half of the Grenztruppen were conscripts, a lower proportion than in other branches of the East German armed forces. Many potential recruits were screened out as potentially unreliable; for instance, actively religious individuals or those with close relatives in West Germany. They were all subjected to close scrutiny to assure their political reliability and were given intensive ideological indoctrination.A special unit of the Stasi secret police worked covertly within the Grenztruppen, posing as regular border guards, between 1968 and 1985, to weed out potential defectors. One in ten officers and one in thirty enlisted men were said to have been recruited by the Stasi as informers. The Stasi regularly interviewed and maintained files on every guard. Stasi operatives were directly responsible for some aspects of security; passport control stations at crossings were manned by Stasi officers wearing Grenztruppen uniforms.The Grenztruppen were closely watched to ensure that they could not take advantage of their inside knowledge to escape across the border. Patrols, watchtowers and observation posts were always manned by two or three guards at a time. They were not allowed to go out of each other's sight in any circumstances. If a guard attempted to escape, his colleagues were under instructions to shoot him without hesitation or prior warning; 2,500 did escape to the West, 5,500 more were caught and imprisoned for up to five years, and a number were shot and killed or injured in the attempt.
The work of the guards involved carrying out repair work on the defences, monitoring the zone from watchtowers and bunkers and patrolling the line several times a day. Border Reconnaissance (Grenzaufklärungszug or GAK) soldiers, an elite reconnaissance force, carried out patrols and intelligence-gathering on the western side of the fence. Western visitors to the border were routinely photographed by the GAKs, who also oversaw work detachments maintaining the fence. The workers would be covered by machine guns to discourage them from attempting to escape. 
Question: What is the name of the group that was instructed to shoot any colleague attempting to escape?

Answer:
Grenztruppen.
