Q: Question: What years did Zulfikar Ali Bhutto serve as prime minister? Passage 1:The LGBT movement has been very active in the new millennium. In the advent of the 2000s, more LGBT organizations were formed to serve specific needs, including sexual health (particularly HIV), psychosocial support, representation in sports events, religious and spiritual needs, and political representation. For example, the political party Ang Ladlad was founded by Danton Remoto, a renowned LGBT advocate, in 2003. The community has also shown their advocacies through the 21st LGBT Metro Manila Pride March held in Luneta Park on 27 June 2015, with the theme, "Fight For Love:Iba-Iba. Sama-Sama". This movement aims to remind the nation that the fight for LGBT rights is a fight for human rights. Advocates are calling on the Philippines to recognize the voices of people of diverse sexual orientations and gender identities. In present time, there remains no umbrella LGBT organization in the Philippines. Therefore, organizations tend to work independently of each other. Due to these divisions, there remains no prioritization of efforts, with organizations focusing on what they consider as important for them.
 Passage 2:Hotwells takes its name from the hot springs which bubble up through the rocks of the Avon Gorge underneath the Clifton Suspension Bridge. The springs were documented in 1480 by William Worcester, the 15th century chronicler and antiquary. He described the waters as being milky and as warm as those at Bath. In 1692 the Society of Merchant Venturers leased the springs and a pump room was built. The pump room of 1696 was demolished and replaced by Hotwells House in 1816 which was itself demolished when the river was widened in 1867. In the Georgian era, Hotwells was developed as a spa including the building of Dowry Square in an attempt to compete with Bath. Many visitors came, including the diarist John Evelyn and the travel writer Celia Fiennes, who hunted for Bristol Diamonds in the gorge. The Somerset historian John Collinson came to Hotwells in 1793 seeking recovery from an unspecified lingering illness and died there on 27 August 1793. 
 Passage 3:It is widely believed that Saudi Arabia has been a major financier of Pakistan's own integrated atomic bomb project since 1974, a programme founded by former prime minister Zulfikar Ali Bhutto. In the 1980s, Chief Martial Law Administrator and President General Zia-ul-Haq paid a state visit to Saudi Arabia where he unofficially told the King that: "Our achievements are yours". This cooperation was allegedly furthered by socialist prime minister Benazir Bhutto in 1995. In 1998, the conservative Prime minister Nawaz Sharif informed Saudi Arabia confidentially before ordering the nuclear tests (see Chagai-I and Chagai-II) in the Weapon-testing labs-III (WTL) located in the Chagai remote site in Balochistan Province of Pakistan. In June 1998, the Prime Minister paid a farewell visit to King Fahd and publicly thanked the Saudi government for supporting the country after the tests. Shortly thereafter, Saudi Minister of Defense Prince Sultan went with Prime Minister Sharif on a tour of a classified institute, the Kahuta Research Laboratories (KRL), where leading scientist Abdul Qadeer Khan briefed the Prince and Prime Minister Sharif on nuclear physics and sensitive issues involving nuclear explosive devices.
