Document 7: Berlin Wall: In 1989 a series of revolutions in nearby Eastern Bloc countries -- Poland and Hungary in particular -- caused a chain reaction in East Germany that ultimately resulted in the demise of the Wall. After several weeks of civil unrest, the East German government announced on 9 November 1989 that all GDR citizens could visit West Germany and West Berlin. Crowds of East Germans crossed and climbed onto the Wall, joined by West Germans on the other side in a celebratory atmosphere. Over the next few weeks, euphoric people and souvenir hunters chipped away parts of the Wall; the governments later used industrial equipment to remove most of what was left. The ``fall of the Berlin Wall ''paved the way for German reunification, which formally took place on 3 October 1990.

Document 11: Scorpions (band): On the Savage Amusement tour in 1988, the Scorpions became only the second Western group (not American) to play in the Soviet Union. Uriah Heep had performed in December 1987 in Leningrad. The following year the band returned to perform at the Moscow Music Peace Festival. As a result, the Scorpions developed an extended Russian fan base and still return to perform. Also in 1989, Scorpions released the compilation album Best of Rockers 'n' Ballads, which, in addition to the band's hits from 1979 to 1988, included several rare or previously unreleased tracks: "Hey You", from the Animal Magnetism sessions; the re-recorded "long version" of "Is There Anybody There?"; and a cover of The Who's "I Can't Explain", which was also included on that same year's Stairway to Heaven/Highway to Hell charity compilation album. This is the Scorpions' only compilation album to be certified platinum in the United States.Wishing to distance themselves from the Savage Amusement style, the band separated from their long-time producer and "Sixth Scorpion", Dieter Dierks, replacing him with Keith Olsen when they returned to the studio in 1990. Crazy World was released that year and displayed a less polished sound. The album was propelled in large part by the massive success of the ballad "Wind of Change".

Crazy World is the band's last album to receive gold or platinum certification in the United States.

Document 13: Berlin Wall: The Berlin Wall (German: Berliner Mauer) was a guarded concrete barrier that physically and ideologically divided Berlin from 1961 to 1989. Constructed by the German Democratic Republic (GDR, East Germany), starting on 13 August 1961, the Wall completely cut off (by land) West Berlin from surrounding East Germany and from East Berlin until government officials opened it in November 1989. Its demolition officially began on 13 June 1990 and finished in 1992. The barrier included guard towers placed along large concrete walls, accompanied by a wide area (later known as the ``death strip '') that contained anti-vehicle trenches,`` fakir beds'' and other defenses. The Eastern Bloc portrayed the Wall as protecting its population from fascist elements conspiring to prevent the ``will of the people ''in building a socialist state in East Germany. In practice, the Wall served to prevent the massive emigration and defection that had marked East Germany and the communist Eastern Bloc during the post-World War II period.
