Eventually the 12-inch (300 mm) 33 13 rpm LP prevailed as the predominant format for musical albums, and 10-inch LPs were no longer issued. The last Columbia Records reissue of any Frank Sinatra songs on a 10-inch LP record was an album called Hall of Fame, CL 2600, issued on October 26, 1956, containing six songs, one each by Tony Bennett, Rosemary Clooney, Johnnie Ray, Frank Sinatra, Doris Day, and Frankie Laine. The 10-inch LP however had a longer life in the United Kingdom, where important early British rock and roll albums such as Lonnie Donegan's Lonnie Donegan Showcase and Billy Fury's The Sound of Fury were released in that form. The 7-inch (175 mm) 45 rpm disc or "single" established a significant niche for shorter duration discs, typically containing one item on each side. The 45 rpm discs typically emulated the playing time of the former 78 rpm discs, while the 12-inch LP discs eventually provided up to one half-hour of recorded material per side.

Did the 45 rpm or 12 inch disc offer longer playing time?
Answer: 12-inch LP

Beer is composed mostly of water. Regions have water with different mineral components; as a result, different regions were originally better suited to making certain types of beer, thus giving them a regional character. For example, Dublin has hard water well-suited to making stout, such as Guinness; while the Plzen Region has soft water well-suited to making Pilsner (pale lager), such as Pilsner Urquell. The waters of Burton in England contain gypsum, which benefits making pale ale to such a degree that brewers of pale ales will add gypsum to the local water in a process known as Burtonisation.

What type of water is good for making stout beer, like Guinness?
Answer: hard water
