Question: Which ground did the Liverpool Football Club play at longer, Anfield or Goodison Park? Passage:Liverpool Football Club is an English association football club based in Liverpool, Merseyside, which competes in the top tier of English football, for the 2019–20 season. The club was formed in 1892 following a disagreement between the board of Everton and club president John Houlding, who owned the club's ground, Anfield. The dispute over rent resulted in Everton leaving Anfield for Goodison Park, which left Houlding with an empty stadium. Not content for his ground to lay idle, he created his own club: Liverpool. Liverpool joined the Lancashire League on their foundation before the 1892–93 season. They ended their inaugural season as league champions, and were elected to The Football League soon afterwards. The club remained in The Football League until 1992, when its First Division was superseded as English football's top level by the newly formed Premier League.

Question: What's the mascot of the team Allen played against in the 66th Minor Counties Championship match? Passage:Allen moved to Lymington, Hampshire in 1964, when his parents took over The Mayflower pub in the town. Shortly after moving there, he began playing for Lymington Cricket Club, where he was initially encouraged to be a seam bowler. While bowling slow left-arm orthodox in the nets at the County Ground, Southampton, he was spotted by Arthur Holt who encouraged him to stick with that bowling style. Having impressed in club cricket for Lymington, Allen briefly played for the Hampshire Second XI, before being selected to play minor counties cricket for Dorset, making his debut for the county in the 1976 Minor Counties Championship against Cornwall. From 1976 to 1983, Allen played a total of 66 Minor Counties Championship matches, the last of which came against Shropshire. He also made a single appearance for the county in the 1983 MCCA Knockout Trophy against Oxfordshire. He took a total of 252 wickets for Dorset. Allen also made a sole List A appearance for Dorset in the 1983 NatWest Trophy against first-class opponents Essex at Dean Park, Bournemouth. In Dorset's innings 111 all out, Allen was dismissed for 7 runs by Neil Foster, while in Essex's innings he bowled 6 wicketless overs and caught Keith Fletcher, with Essex winning by 7 wickets.

Question: Who was the successor  of the person serving as South Vietnamese President during Prime Minister Tunku Abdul Rahman visit in 1958? Passage:Relations with the former state of South Vietnam were established when South Vietnam recognised the Federation of Malaya's independence on 1957. From that point, Malaya provided aid to the South Vietnamese regime in its fight against the Viet Cong and North Vietnamese army. Malayan Prime Minister Tunku Abdul Rahman made a first visit on 1958 which was reciprocated twice by the South Vietnamese President Ngô Đình Diệm on 28–31 January 1958 and in October 1961. By 1963, when Malaya transformed into Malaysia (with an additional territory in the island of Borneo), the main government in Kuala Lumpur worried the influence of North Vietnamese communists would threaten its existence in accordance to the Domino theory, thus changing its position to become very supportive of the American involvement in the Vietnam War as Malaysia had also experienced a communist insurgency of its own. Tunku Abdul Rahman then expressed these concerns in December 1966 and called on the United States and the United Kingdom to provide increased logistical support to war efforts in Vietnam. Malaysia hosted training courses in public administration and jungle warfare for government officials, and provided motorcycles to bolster the South Vietnamese police and military logistical capabilities. Towards the end of the Vietnam War in 1975, Malaysia closed its embassy in Saigon in two stages; first it withdrew the embassy dependants on 12 April 1975, before a complete closure 16 days later—two days before the fall of Saigon. Malaysia had also extended recognition to the short-lived Provisional Revolutionary Government of the Republic of South Vietnam within days of its formation in May 1975, citing Malaysia's impartial position on political ideology and social system.
