Task: Question Generation
Input (English): Passage: In February 1954 Gao Gang, the head of the State Planning Council, was purged from government; he killed himself only months later.  His presence in the painting immediately on Mao's left placed arts officials in a quandary.  Given its popularity among officials and the people, The Founding of the Nation had to be shown at the Second National Arts Exhibition (1955), but it was unthinkable that Gao, deemed a traitor, should be depicted.  Accordingly Dong was ordered to remove Gao from the painting, which he did.
Wu Hung described The Founding of the Nation as "arguably the most celebrated work of official Chinese art".  He noted that the painting is the only "canonized" one depicting the October 1 ceremony, and that other artists have tended to give the people's perspective, subjecting themselves to Mao's gaze.  The painting is a modern-day example of damnatio memoriae, the alteration of artworks or other objects to remove the image or name of a disfavored person.  Deng Zhangyu, in a 2014 article, called the painting "the most significant historical image of China's founding".  Wu Hung suggested that the alterations to it over the years, while always showing Mao proclaiming the new government, parallel the changes that have come to China's leadership during the years of Communist governance.  Andrews wrote that "its greatest importance to the art world was its elevation as a model of party-approved oil painting".  Writer Wu Bing in 2009 called it "a milestone in Chinese oil painting, boldly incorporating national styles".  The painting has never been as highly regarded in the West as in China; according to Andrews, "art history students have been known to roar with laughter when slides of it appear on the screen".  Art historian Michael Sullivan dismissed it as mere propaganda.  Today, following a merger of museums, both paintings are in the National Museum of China, on Tiananmen Square.
Output (English): What is the name of that which Michael Sullivan dismissed as mere propaganda?
