Problem: Background: Mian Muhammad Nawaz Sharif (Urdu/Punjabi: myN mHmd nwz shryf, born 25 December 1949) is a Pakistani businessman and politician who served as the Prime Minister of Pakistan from 2013 until he was disqualified for life from office by the Supreme Court of Pakistan in 2017. He had previously served as the Prime Minister twice in the 90s (1990-93 and 1997-99) and the Chief Minister of Punjab from 1985 to 1990. He is Pakistan's longest-serving prime minister. Born into the upper-middle class Sharif family in Lahore, he is the son of Ittefaq and Sharif Group founder, Muhammad Sharif, and the elder-brother of three-time elected Punjab Chief Minister, Shehbaz.
Context: On 7 November 1990, the newly elected prime minister announced his nuclear policy and in public television, Sharif responded that: "The peaceful [atomic] programme of which... it would be accelerated to accommodate growing [nuclear] [e]nergy needs and to make up for rising [oil] prices. And, of course, (Pakistan) will to construct new nuclear power plants." On 26 November, Sharif authorised talks with the US to solve the nuclear crises after the US had tightened its embargo on Pakistan, prompting Sharif to send his government's Treasure Minister Sartaj Aziz to held talks on Washington. It was widely reported in Pakistan that the US Assistant Secretary of State Teresita Schaffer had told the Foreign Minister Shahabzada Yaqub Khan to halt the uranium enrichment programme.  In December, France's Commissariat a l'energie atomique agreed to provide a commercial 900MW power plant, but plans did not materialise as France wanted Pakistan to provide entire financial funds for the plant. On December, the financial embargo was placed and the country's economy felt a distress that prompted Sharif to replace his Treasure minister. Sharif then used Munir Ahmad Khan to have convinced IAEA to allow Pakistan for a nuclear plant in Chashman where Khan intensively lobbied in IAEA for the nuclear power plant. In December 1990, IAEA allowed Pakistan to established CHASNUPP-I, signed with China; the IAEA also gave approval of upgrading of the KANUPP-I in 1990. During his first term, Sharif intensified his non-nuclear weapon policy and strictly followed the policy of deliberate nuclear ambiguity which was also continued by Benazir as well. Responding to US embargo, Sharif publicly announced that: "Pakistan possessed no [atomic] bomb... Pakistan would be happy to sign the Nuclear Nonproliferation Treaty (NPT) but it must be provided "first" to India to do the same."  Sharif intensified his move to enhance the Pakistan's integrated nuclear development and authorised projects that seemed to be important in his point of views. Sharif also promoted the peaceful nuclear energy programme, and signed the CHASNUPP-I reactor with People's Republic of China for the commercial electricity use. Sharif also responded to use the nuclear development in more of economical usage, benefited for the country's economy and its extension to the civil society. His policies to make the nuclear program for economical use was also continued by Benazir Bhutto and Pervez Musharraf.

Problem: Background: Martina Hingis (born 30 September 1980) is a Swiss former professional tennis player who spent a total of 209 weeks as the singles world No. 1 and 90 weeks as doubles world No. 1, holding both No. 1 rankings simultaneously for 29 weeks. She won five Grand Slam singles titles, thirteen Grand Slam women's doubles titles, winning a calendar-year doubles Grand Slam in 1998, and seven Grand Slam mixed doubles titles; for a combined total of twenty-five major titles. In addition, she won the season-ending WTA Finals two times in singles and three times in doubles, and an Olympic silver medal.
Context: In 2001, Switzerland, with Hingis and Roger Federer on its team, won the Hopman Cup. Hingis didn't drop a set in any of her singles matches during the event, defeating Tamarine Tanasugarn, Nicole Pratt, Amanda Coetzer, and Monica Seles. Federer was later quoted as saying: "I learned a lot from her, especially the two years I was here - once as a hitting partner and once as a partner with Martina. Definitely she helped me to become the player I am today."  Hingis reached her fifth consecutive Australian Open final in 2001, defeating both of the Williams sisters en route, before losing to Jennifer Capriati. She briefly ended her coaching relationship with her mother Melanie early in the year but had a change of heart two months later just before the French Open. 2001 was her least successful year in several seasons, with only three tournament victories in total. She lost her No. 1 ranking for the last time (to Jennifer Capriati) on 14 October 2001. In that same month, Hingis underwent surgery on her right ankle.  Coming back from injury, Hingis won the Australian Open doubles final at the start of 2002 (again teaming with Anna Kournikova) and reached a sixth straight Australian Open final in singles, again facing Capriati. Hingis led by a set and 4-0 and had four match points but lost in three sets. In May 2002, she needed another ankle ligament operation, this time on her left ankle. After that, she continued to struggle with injuries and was not able to recapture her best form.  In February 2003, at the age of 22, Hingis announced her retirement from tennis, due to her injuries and being in pain. "I want to play tennis only for fun and concentrate more on horse riding and finish my studies." In several interviews, she has indicated she wishes to return to her home country and coach full-time.  During this segment of her tennis career, Hingis won 40 singles titles and 36 doubles events. She held the World No. 1 singles ranking for a total of 209 weeks (fifth most following Steffi Graf, Martina Navratilova (after whom she was named), Chris Evert, and Serena Williams). In 2005, Tennis magazine put her in 22nd place in its list of 40 Greatest Players of the TENNIS era.
