Background: Janis Lyn Joplin (; January 19, 1943 - October 4, 1970) was an American rock singer and songwriter; one of the most successful and widely-known female rock stars of her era. After releasing three albums, she died of a heroin overdose at the age of 27. A fourth album, Pearl, was released in January 1971, just over three months after her death.
Context: Joplin appeared at Woodstock starting at approximately 2:00 a.m., on Sunday, August 17, 1969. Joplin informed her band that they would be performing at the concert as if it were just another gig. On Saturday afternoon, when she and the band were flown by helicopter with the pregnant Joan Baez and Baez's mother from a nearby motel to the festival site and Joplin saw the enormous crowd, she instantly became extremely nervous and giddy. Upon landing and getting off the helicopter, Joplin was approached by reporters asking her questions. She referred them to Caserta as she was too excited to speak. Initially Joplin was eager to get on the stage and perform, but was repeatedly delayed as bands were contractually obliged to perform ahead of Joplin. Faced with a ten-hour wait after arriving at the backstage area, Joplin shot heroin and drank alcohol with Caserta, and by the time of reaching the stage, Joplin was "three sheets to the wind". During her performance, Joplin's voice became slightly hoarse and wheezy, and she struggled to dance.  Joplin pulled through, however, and engaged frequently with the crowd, asking them if they had everything they needed and if they were staying stoned. The audience cheered for an encore, to which Joplin replied and sang "Ball and Chain". Pete Townshend, who performed with the Who later in the same morning after Joplin finished, witnessed her performance and said the following in his 2012 memoir: "She had been amazing at Monterey, but tonight she wasn't at her best, due, probably, to the long delay, and probably, too, to the amount of booze and heroin she'd consumed while she waited. But even Janis on an off-night was incredible."  Janis remained at Woodstock for the remainder of the festival. Starting at approximately 3:00 a.m. on Monday, August 18, Joplin was among many Woodstock performers who stood in a circle behind Crosby, Stills & Nash during their performance, which was the first time anyone at Woodstock ever had heard the group perform with Neil Young. This information was published by David Crosby in 1988. Later in the morning of August 18, Joplin and Joan Baez sat in Joe Cocker's van and witnessed Hendrix's close-of-show performance, according to Baez's memoir And a Voice to Sing With (1989).  Still photographs in color show Joplin backstage with Grace Slick the day after Joplin's performance, wherein Joplin appears to be very happy. Joplin was ultimately unhappy with her performance, however, and blamed Caserta. Her singing was not included (by her own insistence) in the 1970 documentary film or the soundtrack for Woodstock: Music from the Original Soundtrack and More, although the 25th anniversary director's cut of Woodstock includes her performance of "Work Me, Lord". The documentary film of the festival that was released to theaters in 1970 includes, on the left side of a split screen, 37 seconds of footage of Joplin and Caserta walking toward Joplin's dressing room tent.

Problem: Background: Muhammad Zia-ul-Haq was born in a Punjabi Arain family in Jalandhar, Punjab State of the British India, on 12 August 1924 as the second child of Muhammad Akbar, who worked as a staff clerk in the Army GHQ of India Command of British Armed Forces in Delhi and Shimla, prior to the independence of Pakistan from British colonial rule in 1947. Most accounts confirm that Zia-ul-Haq came from a religious family and religion played an important part in molding his personality. His father was known as ''Maulvi'' Akbar Ali due to his religious devotion. He completed his initial education in Simla and then attended St. Stephen's College of the University of Delhi for his BA degree in History, which he graduated with highest marks in the college in 1943.
Context: After assuming power as Chief Martial Law Administrator, Zia shortly appeared on national television, PTV promising to hold new and neutral parliamentary elections within the next 90 days  My sole aim is to organise free and fair elections which would be held in October this year. Soon after the polls, power will be transferred to the elected representatives of the people. I give a solemn assurance that I will not deviate from this schedule.  He also stated that the Constitution of Pakistan had not been abrogated, but temporarily suspended. Zia did not trust the civilian institutions and legislators to ensure the country's integrity and sovereignty therefore, in October 1977, he announced the postponement of the electoral plan and decided to start an accountability process for the politicians. On television, Zia strongly defended his decision for postponing the elections and demanded that "scrutiny of political leaders who had engaged in malpractice in the past". Thus, the PNA adopted its policy of "retribution first, elections later". Zia's policy severely tainted his credibility as many saw the broken promise as malicious. Another motive was that Zia widely suspected that once out of power the size of the Pakistan Peoples Party rallies would swell and better performance in elections was possible. This led to request for postponement of elections by the right-wing Islamists as well as left-wing socialists, formerly allied with Bhutto, which displaced Bhutto in the first place. Zia dispatched an intelligence unit, known as ISI's Political Wing, sending Brigadier-General Taffazul Hussain Siddiqiui, to Bhutto's native Province, Sindh, to assess whether people would accept martial law. The Political Wing also contacted the several right-wing Islamists and conservatives, promising an election, with PNA power-sharing the government with Zia. Zia successfully divided and separated the secular forces from right-wing Islamists and conservatives, and later purged each member of the secular front.  A Disqualification Tribunal was formed, and several individuals who had been members of parliament were charged with malpractice and disqualified from participating in politics at any level for the next seven years. A white paper document was issued, incriminating the deposed Bhutto government on several counts.  It is reported by senior officers that when Zia met federal secretaries for the first time as leader of the country after martial law, he said that "He does not possess the charisma of Bhutto, personality of Ayub Khan or the legitimacy of Liaquat Ali Khan" thereby implying how can he be marketed.
