Question: Of the two bandmembers that left P-Funk with Haskins, which was the oldest? Passage 1:The Channel is of geologically recent origin, having been dry land for most of the Pleistocene period. Before the Devensian glaciation (the most recent glacial period, which ended around 10,000 years ago), Britain and Ireland were part of continental Europe, linked by an unbroken Weald–Artois anticline, a ridge that acted as a natural dam holding back a large freshwater pro-glacial lake in the Doggerland region, now submerged under the North Sea. During this period the North Sea and almost all of the British Isles were covered by ice. The lake was fed by meltwater from the Baltic and from the Caledonian and Scandinavian ice sheets that joined to the north, blocking its exit. The sea level was about lower than it is today. Then, between 450,000 and 180,000 years ago, at least two catastrophic glacial lake outburst floods breached the Weald–Artois anticline.
 Passage 2:By 1970, the five Parliaments singers were touring with five backing musicians known separately as Funkadelic. The highly rehearsed performances and suited look of The Parliaments gave way to the members dressing in their own outrageous styles. Haskins wore long johns on stage. Due to the contractual issues surrounding the group name, Clinton signed the band as Funkadelic to Westbound Records. The ensemble released their first album Funkadelic in 1970. Clinton also renamed his group of singers Parliament (but still with the Funkadelic musicians as official members) and signed that act to the Holland-Dozier-Holland-owned record label, Invictus. Parliament released their first album Osmium in 1970. Clinton now had two groups that were actually one entity. Under the name Funkadelic, the ensemble was geared towards a rock audience, and as Parliament it was aimed at a soul music audience. Collectively, they became known as Parliament-Funkadelic, or P-Funk. Haskins contributed to P-Funk as a writer through 1972. He toured and appeared on P-Funk albums as a singer, and occasionally as a guitarist, throughout the 1970s. In June 1977 at the height of P-Funk's popularity, Haskins (along with other original Parliaments Calvin Simon and Grady Thomas) left the ensemble over financial and management disputes with Clinton.
 Passage 3:Kim Hong-il (23 September 1898 – 8 August 1980) was a Korean independence activist and a general of the Second Sino-Japanese War and the Korean War, who later became a diplomat and politician in South Korea. Born in North Pyongan, he did his early schooling in China and Korea, and had a brief career as a teacher before his connections with the nascent Korean independence movement led to his imprisonment. He fled into exile in China in 1918, and served in the Kuomintang's National Revolutionary Army from 1926 to 1948, following which he moved to the newly-independent South Korea to join the Republic of Korea Army. He commanded South Korea's I Corps during the first year of the Korean War, and was then sent to Taipei as South Korea's ambassador to the Republic of China, which by then had retreated to Taiwan. His assignment there ultimately lasted nine years. He returned to South Korea in 1960 following the April Revolution which ended the rule of Syngman Rhee, and served briefly as Minister of Foreign Affairs under the Park Chung-hee junta. He ran for the National Assembly, first unsuccessfully in 1960 and 1963, and was then elected in 1967 and became a major figure in the opposition New Democratic Party.
