In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Question: Passage: After Quiriguá's pivotal victory over Copán in 738, K'ak' Tiliw Chan Yopaat rebuilt the main group in the image of Copán itself. Thus, the acropolis, palace, and ballcourt all lie at the southern end of the Great Plaza. The ceremonial centre is laid out around three plazas, the northernmost is the Great Plaza. This plaza measures 325 m (1,066 ft) from north to south and is the largest plaza in the whole Maya region. At the southern end of the Great Plaza is the Ballcourt Plaza, surrounded on three sides by structures associated with the acropolis. The Acropolis Plaza is a fully enclosed plaza within the acropolis itself. The area to the west of the Ballcourt Plaza was probably the riverside docking area and there is evidence that the southern part of the Great Plaza was a marketplace. A number of ceramic-lined wells have been excavated close to the site core, these were all built in the 8th century and although some continued in use into the 9th century, none are known to have been built that late.
1A-1 is an enormous platform forming the northern part of the Great Plaza. It measures 100 by 85 metres (328 by 279 ft) and rises 0.5 metres (20 in) above the level of the southern part of the plaza. It forms the northern portion of the Great Plaza, being built by K'ak' Tiliw Chan Yopaat when he extended the plaza northward. The platform was built from river cobbles and was paved with stone slabs. Platform 1A-1 supported the stelae A, C, D, E and F and Zoomorph B. The platform was built in two phases over about 20 years.
1A-3 is a large mound marking the northern edge of the Great Plaza. It originally measured 82.5 by 20 metres (271 by 66 ft) and was 7 metres (23 ft) high. A 63-metre (207 ft) wide stairway climbed the southern face of the structure from the plaza. The structure was later extended to the north but this second phase of construction was never finished.
The acropolis is the largest architectural complex at Quiriguá, it lies at the southern limit of the ceremonial centre of the city. It is a complex construction, with new buildings and features being added over time. Construction of the acropolis began in 550 and continued through to 810 when the site was abandoned. The acropolis was a palace complex used primarily as an elite residence and for administrative purposes. The acropolis complex includes structures 1B-1, 1B-2, 1B-3, 1B-4, 1B-5 and 1B-6. Excavations of the acropolis encountered the fallen remains of corbel arches, but none are still standing.

Answer: What plaza is at the Ballcourt Plaza at the southern end of?


Question: Passage: The siege was captured by Pathé News cameras—one of their earliest stories and the first siege to be captured on film—and it included footage of Churchill in attendance. When the newsreels were screened in cinemas, Churchill was booed with shouts of "shoot him" from audiences. His presence was controversial to many and the Leader of the Opposition, Arthur Balfour, remarked, "He [Churchill] was, I understand, in military phrase, in what is known as the zone of fire—he and a photographer were both risking valuable lives. I understand what the photographer was doing, but what was the right hon. Gentleman doing? That I neither understood at the time, nor do I understand now." Jenkins suggests that he went simply because "he could not resist going to see the fun himself".An inquest was held in January into the deaths at Houndsditch and Sidney Street. The jury took fifteen minutes to reach the conclusion that the two bodies located were those of Svaars and Sokoloff, and that Tucker, Bentley and Choate had been murdered by Gardstein and others in the course of the burglary attempt. Rosen was arrested on 2 February at work in Well Street, Hackney, and Hoffman was taken into custody on 15 February. The committal proceedings spread from December 1910—with Milstein and Trassjonsky appearing—to March 1911, and included Hoffman from 15 February. The proceedings consisted of 24 individual hearings. In February Milstein was discharged on the basis that there was insufficient evidence against her; Hoffman, Trassjonsky and Federoff were released in March on the same basis.The case against the four remaining arrested gang members was heard at the Old Bailey by Mr Justice Grantham in May. Dubof and Peters were accused of Tucker's murder, Dubof, Peters, Rosen and Vassilleva were charged with "feloniously harbouring a felon guilty of murder", and for "conspiring and agreeing together and with others unknown to break and enter the shop of Henry Samuel Harris with intent to steal his goods." The case lasted for eleven days; there were problems with the proceedings because of the language difficulties and the chaotic personal lives of the accused. The case resulted in acquittals for all except Vassilleva, who was convicted of conspiracy in the burglary. She was sentenced to two years' imprisonment; her conviction was later overturned on appeal.After the high levels of criticism aimed at the Aliens Act, Churchill decided to strengthen the legislation, and proposed the Aliens (Prevention of Crime) Bill under the Ten Minute Rule. The MP Josiah C Wedgwood objected, and wrote to Churchill to ask him not to introduce the hard-line measures "You know as well as I do that human life does not matter a rap in comparison with the death of ideas and the betrayal of English traditions." The bill did not become law.

Answer: Which of the people arrested was released first?


Question: Passage: In 1943, a British naval officer from Canada, Commander Bolton and a few surviving crew members of his 50-man submarine Gauntlet swim ashore after unsuccessfully attacking German battleship Lindendorf. After a review, Captain Bolton is cleared of any wrongdoing and placed in charge of a small group of experimental X class submarines. Bolton is assigned by Vice-Admiral Redmayne to quickly train crews to man the submarines and sink the Lindendorf while it is hidden away in a Norwegian fiord.
Commander Bolton is to train three 4-man crews along the northern coast of Scotland for a trio of midget submarines equipped with side cargoes of explosives. He must overcome tensions with some of his former crew members, while keeping their activities hidden from outsiders and German airplanes. The crews successfully fend off an attack by German parachute commandos, who discover their base. Bolton is forced to make hasty preparations for his attack before their submarine base can be destroyed.
Two of the submarines are lost while attempting to cut through submarine nets at the entrance to the fiord. X-2, is sunk by a German E-boat's depth charges, and a second, the X-1, is scuttled. One submarine crew is captured and taken to the German battleship for interrogation. X-3, the surviving submarine penetrates the submarine nets in the fiord and places explosives under the German battleship. The submarine then manages to escape as the battleship explodes.

Answer:
What is the name of the submarine that attacked the battleship in 1943?
