Question: Which of Alan's brothers was older, Irvin or Stan? Passage 1:Brown was born in 1937 in Lewes, Sussex, one of six brothers who all played football; two, Irvin and Stan, also played in the Football League. He played local football for Lewes St Mary's and Portslade before being called up for National Service. A tall, heavily built man, Brown was serving in Gibraltar in March 1958 when he was recommended to Brighton & Hove Albion as a promising centre half; he signed for the club six months later, the day after his brother Irvin, also a centre half, left it. He made his first-team debut three years later, by which time he had converted to play at centre forward, and made eight appearances, scoring twice, in the first half of the 1961–62 Second Division season. In January 1962, he joined Exeter City, managed by former Brighton team-mate Glen Wilson. He scored three goals from eleven Division Four appearances, and left at the end of the season for non-league football with clubs including Hastings United and Dover. After football, Brown worked as a landscape gardener. He died in Lewes in 2016 at the age of 78.
 Passage 2:The Shiromani Akali Dal held a protest over the SYL issue on 12 April 2016 in Ludhiana, whilst accusing national convenor of Aam Aadmi Party and Chief Minister of Delhi Arvind Kejriwal and his government of "double-speak" and "anti-Punjab stand". On 11 November 2016, all Indian National Congress MLAs of the Punjab Legislative Assembly resigned in protest at the Supreme Court's decision that the state's termination of the link canal was unconstitutional. Aam Aadmi Party began an indefinite protest on the same day at Kapoori village, blaming both the Shiromani Akali Dal and Congress for SYL. Apprehending law and order problem over the issue, the Punjab Police deployed the Rapid Action Force in parts of Punjab, sealed the border with Haryana and increased patrolling on the National Highway-1 on 12 November. A Congress rally was organised on 13 November at Khuian Sarwar village. President of Punjab Pradesh Congress Committee Amarinder Singh declared that not a single drop a water will go out of Punjab while also announcing that a Congress delegation including MPs and MLAs would meet President of India Pranab Mukherjee on the issue. The delegation met the President on 17 November, urging him to form a panel to look into the SYL issue and direct the Union government to consider ground realities and water availability in the state before taking any action on advice of the Supreme Court. Amarinder resigned from Lok Sabha on 23 November in protest against the issue. A delegation of Punjab government's ministers met the President on 28 November, urging him not to accept any advice against the riparian water rights. The Akali Dal held a rally at Moga on 8 December regarding the issue. Chief Minister Prakash Singh Badal stated that the controversy had been resolved after hiving back the land meant for the canal to the original owners. He also stated that Punjab didn't have a single drop of water to spare.
 Passage 3:In 1479, the Lord of Béarn, Francis Phoebus, inherited the Kingdom of Navarre, across the Pyrenees to the southwest. The two sovereign principalities remained in personal union until their extinction. Béarn went on to be ruled by Henry II of Navarre, who inherited it from his mother. In 1512, the Kingdom of Navarre was almost entirely occupied by Spain; only Lower Navarre, north of the Pyrenees escaped Spanish permanent occupation. The Bearnese monarchs extended the use of Occitan to Navarre after 1512, despite the fact that it was not the vernacular there, where Basque was the tongue of the people. The Estates of Navarre convoked in 1522 (or in 1523, according to other sources) kept records in Occitan, as did the Chancery of Navarre created in 1524. When Henry II revised the Fueros of Navarre in 1530, he had them translated from Castilian into Occitan.
