Task: Question Generation
Input (English): Passage: The East German government sought to defuse the situation by relaxing the country's border controls with effect from 10 November 1989; the announcement was made on the evening of 9 November 1989 by Politbüro member Günter Schabowski at a somewhat chaotic press conference in East Berlin, who proclaimed the new control regime as liberating the people from a situation of psychological pressure by legalising and simplifying migration. Misunderstanding the note passed to him about the decision to open the border, he announced the border would be opened "immediately, without delay", rather than from the following day as the government had intended. Crucially, it was neither meant to be an uncontrolled opening nor to apply to East Germans wishing to visit the West as tourists. At an interview in English after the press conference, Schabowski told the NBC reporter Tom Brokaw that "it is no question of tourism. It is a permission of leaving the GDR [permanently]."As the press conference had been broadcast live, within hours, thousands of people gathered at the Berlin Wall demanding that the guards open the gates. The border guards were unable to contact their superiors for instructions and, fearing a stampede, opened the gates. The iconic scenes that followed – people pouring into West Berlin, standing on the Wall and attacking it with pickaxes – were broadcast worldwide.While the eyes of the world were on the Mauerfall (the fall of the Wall) in Berlin, a simultaneous process of Grenzöffnung (border opening) was taking place along the entire length of the inner German border. Existing crossings were opened immediately. Within the first four days, 4.3 million East Germans – a quarter of the country's entire population – poured into West Germany. At the Helmstedt crossing point on the Berlin–Hanover autobahn, cars were backed up for 65 km (40 mi); some drivers waited 11 hours to cross to the West. The border was opened in stages over the next few months. Many new crossing points were created, reconnecting communities that had been separated for nearly 40 years. BBC correspondent Ben Bradshaw described the jubilant scenes at the railway station of Hof in Bavaria in the early hours of 12 November:
It was not just the arrivals at Hof who wore their emotions on their sleeves. The local people turned out in their hundreds to welcome them; stout men and women in their Sunday best, twice or three times the average age of those getting off the trains, wept as they clapped. "These are our people, free at last," they said ... Those arriving at Hof report people lining the route of the trains in East Germany waving and clapping and holding placards saying: 'We're coming soon."
Even the East German border guards were not immune to the euphoria. One of them, Peter Zahn, described how he and his colleagues reacted to the opening of the border:.
