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.
Example: Passage: Nearing London, Oliver encounters Jack Dawkins, a pickpocket more commonly known by the nickname the "Artful Dodger", and his sidekick, a boy of a humorous nature named Charley Bates, but Oliver's innocent and trusting nature fails to see any dishonesty in their actions. The Dodger provides Oliver with a free meal and tells him of a gentleman in London who will "give him lodgings for nothing, and never ask for change". Grateful for the unexpected assistance, Oliver follows the Dodger to the "old gentleman's" residence. In this way Oliver unwittingly falls in with an infamous Jewish criminal known as Fagin, the gentleman of whom the Artful Dodger spoke. Ensnared, Oliver lives with Fagin and his gang of juvenile pickpockets in their lair at Saffron Hill for some time, unaware of their criminal occupations. He believes they make wallets and handkerchiefs.

Problem: Passage: On 1 November, Imre Nagy received reports that Soviet forces had entered Hungary from the east and were moving towards Budapest. Nagy sought and received assurances (which proved false) from Soviet ambassador Yuri Andropov that the Soviet Union would not invade. The Cabinet, with János Kádár in agreement, declared Hungary's neutrality, withdrew from the Warsaw Pact, and requested assistance from the diplomatic corps in Budapest and Dag Hammarskjöld, UN Secretary-General, to defend Hungary's neutrality. Ambassador Andropov was asked to inform his government that Hungary would begin negotiations on the removal of Soviet forces immediately.On 3 November, a Hungarian delegation led by the Minister of Defense Pál Maléter was invited to attend negotiations on Soviet withdrawal at the Soviet Military Command at Tököl, near Budapest. At around midnight that evening, General Ivan Serov, Chief of the Soviet Security Police (KGB) ordered the arrest of the Hungarian delegation, and the next day, the Soviet army again attacked Budapest. During the early hours of 4 November, Ferenc Münnich announced on Radio Szolnok the establishment of the "Revolutionary Workers'-Peasants' Government of Hungary".
The second Soviet intervention, codenamed "Operation Whirlwind", was launched by Marshal Ivan Konev. The five Soviet divisions stationed in Hungary before 23 October were augmented to a total strength of 17 divisions. The 8th Mechanized Army under command of Lieutenant General Hamazasp Babadzhanian and the 38th Army under Lieutenant General Hadzhi-Umar Mamsurovs from the nearby Carpathian Military District were deployed to Hungary for the operation. Some rank-and-file Soviet soldiers reportedly believed they were being sent to Berlin to fight German fascists. By 21:30 on 3 November, the Soviet Army had completely encircled Budapest.At 03:00 on 4 November, Soviet tanks penetrated Budapest along the Pest side of the Danube in two thrusts: one up the Soroksári road from the south and the other down the Váci road from the north. Thus before a single shot was fired, the Soviets had effectively split the city in half, controlled all bridgeheads, and were shielded to the rear by the wide Danube river. Armoured units crossed into Buda and at 04:25 fired the first shots at the army barracks on Budaörsi Road. Soon after, Soviet artillery and tank fire was heard in all districts of Budapest. Operation Whirlwind combined air strikes, artillery, and the co-ordinated tank-infantry action of 17 divisions. Soviet army used: medium tanks T-34-85 and new T-54, heavy IS-3 tanks, 152 mm. ISU-152 Assault guns and BTR-152 armored carriers with the opened cover,.
