Given the task definition, example input & output, solve the new input case.
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.
Output: Who believes Fagin's gang make wallets and handkerchiefs?.
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 case for you: Passage: The Belarusian government sponsors annual cultural festivals such as the Slavianski Bazaar in Vitebsk, which showcases Belarusian performers, artists, writers, musicians, and actors. Several state holidays, such as Independence Day and Victory Day, draw big crowds and often include displays such as fireworks and military parades, especially in Vitebsk and Minsk. The government's Ministry of Culture finances events promoting Belarusian arts and culture both inside and outside the country.
Belarusian literature began with 11th- to 13th-century religious scripture, such as the 12th-century poetry of Cyril of Turaw.By the 16th century, Polotsk resident Francysk Skaryna translated the Bible into Belarusian. It was published in Prague and Vilnius sometime between 1517 and 1525, making it the first book printed in Belarus or anywhere in Eastern Europe. The modern era of Belarusian literature began in the late 19th century; one prominent writer was Yanka Kupala. Many Belarusian writers of the time, such as Uładzimir Žyłka, Kazimir Svayak, Yakub Kolas, Źmitrok Biadula, and Maksim Haretski, wrote for Nasha Niva, a Belarusian-language paper published that was previously published in Vilnius but now is published in Minsk.
After Belarus was incorporated into the Soviet Union, the Soviet government took control of the Republic's cultural affairs. At first, a policy of "Belarusianization" was followed in the newly formed Byelorussian SSR. This policy was reversed in the 1930s, and the majority of prominent Belarusian intellectuals and nationalist advocates were either exiled or killed in Stalinist purges. The free development of literature occurred only in Polish-held territory until Soviet occupation in 1939. Several poets and authors went into exile after the Nazi occupation of Belarus and would not return until the 1960s.The last major revival of Belarusian literature occurred in the 1960s with novels published by Vasil Bykaŭ and Uladzimir Karatkievich. An influential author who devoted his work to awakening the awareness of the catastrophes the country has suffered, was Ales Adamovich. He was named by Svetlana Alexievich, the Belarusian winner of the Nobel Prize in Literature 2015, as "her main teacher, who helped her to find a path of her own".
Output:
What is the name of the policy that was reversed in the 1930s?
