You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

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.
Solution: Who believes Fagin's gang make wallets and handkerchiefs?.
Why? This question is based on the following sentence in the passage "He believes they make wallets and handkerchiefs". It evaluates the understanding that the pronoun "he" refers to name "Oliver". You can ask questions like this one about most pronouns in a paragraph.

New input: Passage: On 5 March 1953, Joseph Stalin died, ushering in a period of moderate liberalization, when most European communist parties developed a reform wing. In Hungary, the reformist Imre Nagy replaced Rákosi, "Stalin's Best Hungarian Disciple", as Prime Minister. However, Rákosi remained General Secretary of the Party, and was able to undermine most of Nagy's reforms. By April 1955, he had Nagy discredited and removed from office. After Khrushchev's "secret speech" of February 1956, which denounced Stalin and his protégés, Rákosi was deposed as General Secretary of the Party and replaced by Ernő Gerő on 18 July 1956. Radio Free Europe (RFE) broadcast the "secret speech" to Eastern Europe on the advice of Ray S. Cline, who saw it as a way to, "as I think I told [Allen Dulles] to say, 'indict the whole Soviet system'."On 14 May 1955, the Soviet Union created the Warsaw Pact, binding Hungary to the Soviet Union and its satellite states in Central and Eastern Europe. Among the principles of this alliance were "respect for the independence and sovereignty of states" and "non-interference in their internal affairs".In 1955, the Austrian State Treaty and ensuing declaration of neutrality established Austria as a demilitarised and neutral country. This raised Hungarian hopes of also becoming neutral and in 1955 Nagy had considered "the possibility of Hungary adopting a neutral status on the Austrian pattern".In June 1956, a violent uprising by Polish workers in Poznań was put down by the government, with scores of protesters killed and wounded. Responding to popular demand, in October 1956, the government appointed the recently rehabilitated reformist communist Władysław Gomułka as First Secretary of the Polish United Workers' Party, with a mandate to negotiate trade concessions and troop reductions with the Soviet government. After a few tense days of negotiations, on 19 October the Soviets finally gave in to Gomułka's reformist demands. News of the concessions won by the Poles, known as Polish October, emboldened many Hungarians to hope for similar concessions for Hungary and these sentiments contributed significantly to the highly charged political climate that prevailed in Hungary in the second half of October 1956.
Solution:
What is the first name of the person who was denounced in Khrushchev's speech?
