Problem: The Administrator of Prussia, the grandmaster of the Teutonic Order Maximilian III, son of emperor Maximilian II died in 1618. When Maximilian died, Albert's line died out, and the Duchy of Prussia passed to the Electors of Brandenburg, forming Brandenburg-Prussia. Taking advantage of the Swedish invasion of Poland in 1655, and instead of fulfilling his vassal's duties towards the Polish Kingdom, by joining forces with the Swedes and subsequent treaties of Wehlau, Labiau, and Oliva, Elector and Duke Frederick William succeeded in revoking king of Poland's sovereignty over the Duchy of Prussia in 1660. The absolutist elector also subdued the noble estates of Prussia.

Problem: While videoconferencing technology was initially used primarily within internal corporate communication networks, one of the first community service usages of the technology started in 1992 through a unique partnership with PictureTel and IBM Corporations which at the time were promoting a jointly developed desktop based videoconferencing product known as the PCS/1. Over the next 15 years, Project DIANE (Diversified Information and Assistance Network) grew to utilize a variety of videoconferencing platforms to create a multi-state cooperative public service and distance education network consisting of several hundred schools, neighborhood centers, libraries, science museums, zoos and parks, public assistance centers, and other community oriented organizations.

Problem: In 1982, the band released the album Hot Space, a departure from their trademark seventies sound, this time being a mixture of rock, pop rock, dance, funk, and R&B. Most of the album was recorded in Munich during the most turbulent period in the band's history, and Taylor and May lamented the new sound, with both being very critical of the influence Mercury's personal manager Paul Prenter had on the singer. May was also scathing of Prenter, who was Mercury's manager from the early 1980s to 1984, for being dismissive of the importance of radio stations, such as the US networks, and their vital connection between the artist and the community, and for denying them access to Mercury. The band stopped touring North America after their Hot Space Tour, as their success there had waned, although they would perform on American television for the only time during the eighth season premiere of Saturday Night Live. Queen left Elektra Records, their label in the United States, Canada, Japan, Australia, and New Zealand, and signed onto EMI/Capitol Records.
