input: During the 2005-06 season, Pires wrangled with Arsenal over a new contract, in the hope of a new two-year deal. In keeping with the club's policy regarding players over 30, Pires was only offered a 12-month extension to his contract, which expired in June 2006.  In May 2006, Pires agreed to an offer from Villarreal CF after a month of speculation, during which time he and Arsenal defeated Villarreal in the Champions League semi-final.  Arsenal fans and players alike were saddened by Pires's departure. His ex-Arsenal teammate Cesc Fabregas told the August 2006 edition of the Sky magazine how sad it was to lose him.  One of the main reasons Pires gave for leaving Arsenal was that he felt he was no longer a first choice under manager Arsene Wenger. Pires was quoted saying: "I have to say I have had some disappointments this season. For instance, I was on the bench very often". Pires additionally suggested that Wenger's decision to withdraw him in the UEFA Champions League Final showed he had slipped in the eyes of his French boss. Pires said that he felt hurt by how Wenger did not trust him anymore, which was a major factor that convinced him that it was time to move on from Arsenal.  On the official Arsenal matchday program for the game against Wigan Athletic on 11 February 2007, Pires revealed his heartbreak of being substituted so early on during the Champions League final. Pires stated: "I was very disappointed. When I saw my number on the fourth official's board to be substituted, I couldn't believe it. It was my last game after six years at the club, a Champions League Final in front of all my family in Paris where I became World Cup champion and it lasted just 12 minutes. That was very hard to take". Pires was in fact substituted on 18 minutes for backup goalkeeper Manuel Almunia after goalkeeper Jens Lehmann who had received a straight red card.

Problem: Background: Sarvepalli Radhakrishnan  listen  (5 September 1888 - 17 April 1975) was an Indian philosopher and statesman who was the first Vice President of India (1952-1962) and the second President of India from 1962 to 1967. One of India's most distinguished twentieth-century scholars of comparative religion and philosophy, his academic appointments included professor of Philosophy at the University of Mysore (1918-1921), the King George V Chair of Mental and Moral Science at the University of Calcutta (1921-1932) and Spalding Professor of Eastern Religion and Ethics at University of Oxford (1936-1952). His philosophy was grounded in Advaita Vedanta, reinterpreting this tradition for a contemporary understanding.
Context: Radhakrishnan was awarded scholarships throughout his academic life. He joined Voorhees College in Vellore but switched to the Madras Christian College at the age of 17. He graduated from there in 1906 with a master's degree in Philosophy, being one of its most distinguished alumni.  Radhakrishnan studied philosophy by chance rather than choice. Being a financially constrained student, when a cousin who graduated from the same college passed on his philosophy textbooks in to Radhakrishnan, it automatically decided his academic course.  Radhakrishnan wrote his thesis for the M.A. degree on "The Ethics of the Vedanta and its Metaphysical Presuppositions". It "was intended to be a reply to the charge that the Vedanta system had no room for ethics." He was afraid that this M.A. thesis would offend his philosophy professor, Dr. Alfred George Hogg. Instead, Hogg commended Radhakrishnan on having done most excellent work. Radhakrishnan's thesis was published when he was only twenty. According to Radhakrishnan himself, the criticism of Hogg and other Christian teachers of Indian culture "disturbed my faith and shook the traditional props on which I leaned." Radhakrishnan himself describes how, as a student,  The challenge of Christian critics impelled me to make a study of Hinduism and find out what is living and what is dead in it. My pride as a Hindu, roused by the enterprise and eloquence of Swami Vivekananda, was deeply hurt by the treatment accorded to Hinduism in missionary institutions.  This led him to his critical study of Indian philosophy and religion and a lifelong defence of Hinduism against "uninformed Western criticism".

Question: Sayyid Ruhollah Musavi Khomeini (Persian: syd rwHllh mwswy khmyny [ru:hol'la:he khomei'ni:] ( listen); 24 September 1902 - 3 June 1989), known in the Western world as Ayatollah Khomeini, was an Iranian Shia Muslim religious leader and politician. He was the founder of Iran as an Islamic republic and the leader of its 1979 Iranian Revolution that saw the overthrow of 2500 years of Persian monarchy and Mohammad Reza Pahlavi, the last Shah of Iran.

Khomeini was not allowed to return to Iran during the Shah's reign (as he had been in exile). On 17 January 1979, the Shah left the country (ostensibly "on vacation"), never to return. Two weeks later, on Thursday, 1 February 1979, Khomeini returned in triumph to Iran, welcomed by a joyous crowd estimated (by BBC) to be of up to five million people. On his chartered Air France flight back to Tehran 120 journalists accompanied him, including three women. One of the journalists, Peter Jennings, asked: "Ayatollah, would you be so kind as to tell us how you feel about being back in Iran?" Khomeini answered via his aide Sadegh Ghotbzadeh: "Hichi" (Nothing). This statement--much discussed at the time and since--was considered by some reflective of his mystical beliefs and non-attachment to ego. Others considered it a warning to Iranians who hoped he would be a "mainstream nationalist leader" that they were in for disappointment.  To others, it was a reflection of an unfeeling leader incapable or unconcerned with understanding the thoughts, beliefs, or the needs of the Iranian populace.  Khomeini adamantly opposed the provisional government of Shapour Bakhtiar, promising "I shall kick their teeth in. I appoint the government." On 11 February (Bahman 22), Khomeini appointed his own competing interim prime minister, Mehdi Bazargan, demanding, "since I have appointed him, he must be obeyed." It was "God's government," he warned, disobedience against him or Bazargan was considered a "revolt against God."  As Khomeini's movement gained momentum, soldiers began to defect to his side and Khomeini declared ill fortune on troops who did not surrender. On 11 February, as revolt spread and armories were taken over, the military declared neutrality and the Bakhtiar regime collapsed. On 30 and 31 March 1979, a referendum to replace the monarchy with an Islamic Republic passed with 98% voting in favour of the replacement, with the question: "should the monarchy be abolished in favour of an Islamic Government?"
