Input: Question: What modern country is Calcutta part of? Passage 1:Having been introduced to the journalist, BBC presenter and sports commentator Peter West in 1969, Nally founded the West Nally Group the following year as a public relations agency with a specialised sporting events mandate. With West as chairman, and managing director Nally its driving force, the company would go on to redefine the sports business industry by pioneering the offering to 'blue chip' companies of exclusive, off-the-shelf packages of sponsorship rights to the world's largest sports tournaments on behalf of the world's leading sports federations. Early successes included securing investment to establish the Masters in snooker, the Squash World Open, and an annual one-day cricket competition which would run for three decades in the UK. In 1976, on brokering an agreement to sponsor the FIFA World Cup, the company assured its reputation as a leading innovator within the expanding sports marketing field. Employing over 400 staff in 14 offices across 11 countries in its heyday in the 1980s and 1990s, West Nally has served as partner to, among others, the International Olympic Committee, the International Federation of Association Football (FIFA), the Union of European Football Associations (UEFA), the Davis Cup and Federation Cup in tennis, the Hockey World Cup, the International Swimming Federation (FINA), the International Rowing Federation (FISA), the International Cycling Union (UCI) and the FIS World Ski Cup. The company helped secure the financial foundations of the first London Marathon, held in 1981, before playing an instrumental role in the inception of the International Association of Athletics Federations' Track and Field Program and in initiating the World Athletics Championships, first held in Helsinki in 1983. For the International Rugby Board (IRB), West Nally helped to commercially package and launch the Rugby World Cup, first held in 1987 in Australia and New Zealand. Known within the industry as the 'university of sports marketing' on account of its comprehensive training procedures responsible for cultivating a generation of leading sports business executives, the company's founder Patrick Nally was in 1988 described by Marketing magazine, along with Adidas owner Horst Dassler and IMG founder Mark McCormack, as one of the "three godfathers of sport" who at one time, between them, "controlled the commercial destinies of almost every major sports event in the world". Credited with first perceiving and harnessing sport's unique potential as a medium for global brand communication, Nally is today alternatively hailed as "the 'Founding Father' of sports marketing", "the father of modern sports marketing", "the founding father of the sports business industry", "the godfather of sports sponsorship" and the 'Dean' of the 'Sports Marketing University'. In 2009, his pioneer status within the industry was recognised with a nomination in the 'Outstanding Contribution' category at SportBusiness Magazine's annual Sports Event Management Awards.
 Passage 2:His plea was approved by the Shella Presbytery on 15 February. He left Shella on 18 February (Wednesday) and spent the following Sunday at Sylhet. He met Benjamin Aitken, an elder of Free Church of Scotland and sub-editor of Calcutta-based newspaper The Englishman, who volunteered to join him in his expedition. His frequent companion Kasinath, a young Assamese Christian who was preaching that afternoon, and one Khasi Christian U Khanai also joined him. On Monday 23 February the four set sail on a boat on Surma River, preaching to people along their journey. They spent Sunday 1 March at Silchar and moved the next day. On the third day they arrived at Jhalnacherra and spent a night at Alexandrapur tea garden where Mary Winchester was kidnapped by Mizo Warriors in 1871, the origin of British encounter with Mizos. On Thursday they continued their journey and after a week on Tlawng River, they reach Guturmukh (Kutbûl Kai in Mizo), a British telegraph station at the Tut River junction, on 11 March. Here they stayed for four days and saw the first thatched huts of Mizos at a distant hill top, including stockades used during the British military expedition. On Sunday 15 March afternoon they met roaming native Mizos for the first time in their boat ride. They were friendly boys between 10 and 15 years old from neighbouring village, Liankunga chiefdom. They exchanged salt and tobacco for the boys' yams and bananas. They gave them some boxes of matches, and Bible pictures. They also sang several songs to them which they "listened with their mouths open." On Monday afternoon they arrived at Changsil, where they camped among the military escort commanded by Captain Williamson. With the army they moved on Thursday to Sairang where they spent the night. Army horses arrived in the next morning and they headed for Aizawl ("Fort Aijal" as it was called). They reached Aizawl at noon on 20 March. They stayed there for four weeks, learning about Mizo lifestyle, distributing Bible pictures and preaching among non-Mizo such as Khasi, Manipuri, and Naga workers stationed there. Full of hope to return and start formal education and evangelism, they left Aizawl on 17 April. He published his appeal to open mission field in Lushai Hills in June and July 1891 issue of Y Goleuad. Welsh General Assembly at Machynlleth in June 1892 decided to adopt Lushai Hills as an extension of the Khasi Hills mission field. By then Williams had died of typhoid on 21 April 1892 at Mawphlang, some 25 km from Shillong city.
 Passage 3:Pearce's first experience of senior football came in the Northern NSW State League Division 1, for Newcastle Jets youth, where coach (and former Australian international) Clayton Zane praised Pearce's potential and passing ability. For the 2014 National Premier Leagues season, Pearce moved to Broadmeadow Magic. In October 2014, it was announced that Pearce had joined Central Coast Mariners' youth squad to play in the 2014–15 National Youth League. He was called up to the senior squad for the first time and was an unused substitute against Sydney FC in an A-League match in November 2014 following an injury to Liam Reddy. Reddy's departure in late 2015 and suspension and international selection for Paul Izzo led Pearce and fellow young 'keeper Tom Heward-Belle to be called up to the senior side. He made his A-League debut for the Mariners in a loss to Western Sydney Wanderers in April 2016. Pearce was in A-League action again a week later, coming on as an early substitute after Paul Izzo suffered a concussion in the opening minute of an eventual loss to Newcastle Jets. On 6 April 2017, he signed a one-year professional contract with Central Coast Mariners.
