Context and question: In 1974, L. Ottens, director of the audio division of Philips, started a small group with the aim to develop an analog optical audio disc with a diameter of 20 cm and a sound quality superior to that of the vinyl record. However, due to the unsatisfactory performance of the analog format, two Philips research engineers recommended a digital format in March 1974. In 1977, Philips then established a laboratory with the mission of creating a digital audio disc. The diameter of Philips's prototype compact disc was set at 11.5 cm, the diagonal of an audio cassette.

Context and question: Bermuda's national cricket team participated in the Cricket World Cup 2007 in the West Indies. Their most famous player is a 130 kilograms (290 lb) police officer named Dwayne Leverock. But India defeated Bermuda and set a record of 413 runs in a One-Day International (ODI). Bermuda were knocked out of the World Cup. Also very well-known is David Hemp, a former captain of Glamorgan in English first class cricket. The annual "Cup Match" cricket tournament between rival parishes St George's in the east and Somerset in the west is the occasion for a popular national holiday. This tournament began in 1872 when Captain Moresby of the Royal Navy introduced the game to Bermuda, holding a match at Somerset to mark forty years since the unjust thraldom of slavery. The East End versus West End rivalry resulted from the locations of the St. George's Garrison (the original army headquarters in Bermuda) on Barrack Hill, St. George's, and the Royal Naval Dockyard at Ireland Island. Moresby founded the Somerset Cricket Club which plays the St. George's Cricket Club in this game (the membership of both clubs has long been mostly civilian).
