Problem: The complete technical disclosure of the Columbia LP by Peter C. Goldmark, Rene' Snepvangers and William S. Bachman in 1949 made it possible for a great variety of record companies to get into the business of making long playing records. The business grew quickly and interest spread in high fidelity sound and the do-it-yourself market for pickups, turntables, amplifier kits, loudspeaker enclosure plans, and AM/FM radio tuners. The LP record for longer works, 45 rpm for pop music, and FM radio became high fidelity program sources in demand. Radio listeners heard recordings broadcast and this in turn generated more record sales. The industry flourished.
What kind of recordings worked best for pop music?

Answer: 45 rpm

Problem: Television has played a major role in the history of the Premier League. The League's decision to assign broadcasting rights to BSkyB in 1992 was at the time a radical decision, but one that has paid off. At the time pay television was an almost untested proposition in the UK market, as was charging fans to watch live televised football. However, a combination of Sky's strategy, the quality of Premier League football and the public's appetite for the game has seen the value of the Premier League's TV rights soar.

Problem: The early settlement was often subject to attack from sea and land, including periodic assaults from Spain and France (both of whom contested England's claims to the region), and pirates. These were combined with raids by Native Americans, who tried to protect themselves from so-called European "settlers," who in turn wanted to expand the settlement. The heart of the city was fortified according to a 1704 plan by Governor Johnson. Except those fronting Cooper River, the walls were largely removed during the 1720s.
Whose 1704 plan was used to fortified the city?

Answer:
Governor Johnson
