Document 4: Indian Science Congress Association: The first meeting of the congress was held from 15 -- 17 January 1914 at the premises of the Asiatic Society, Calcutta. Honorable justice Sir Ashutosh Mukherjee, the then Vice Chancellor of the University of Calcutta presided over the Congress. One hundred and five scientists from different parts of India and abroad attended it.

Document 6: 1896 Summer Olympics: On 18 June 1894, Coubertin organised a congress at the Sorbonne, Paris, to present his plans to representatives of sports societies from 11 countries. Following his proposal's acceptance by the congress, a date for the first modern Olympic Games needed to be chosen. Coubertin suggested that the Games be held concurrently with the 1900 Universal Exposition of Paris. Concerned that a six-year waiting period might lessen public interest, congress members opted instead to hold the inaugural Games in 1896. With a date established, members of the congress turned their attention to the selection of a host city. It remains a mystery how Athens was finally chosen to host the inaugural Games. In the following years both Coubertin and Demetrius Vikelas would offer recollections of the selection process that contradicted the official minutes of the congress. Most accounts hold that several congressmen first proposed London as the location, but Coubertin dissented. After a brief discussion with Vikelas, who represented Greece, Coubertin suggested Athens. Vikelas made the Athens proposal official on 23 June, and since Greece had been the original home of the Olympics, the congress unanimously approved the decision. Vikelas was then elected the first president of the newly established International Olympic Committee (IOC).
Document 7: Hard Rock Cafe: In 1990, The Rank Group, a London-based leisure company, acquired Mecca Leisure Group and continued expansion of the concept in its geographic territory. Rank went on to purchase Hard Rock America from Peter Morton as well as Hard Rock Canada from Nick Bitove. After the completion of these acquisitions, Rank gained worldwide control of the brand. In March 2007, the Seminole Tribe of Florida acquired Hard Rock Cafe International, Inc. and other related entities from Rank for US$965 million.In 2008, anonymous members of the wait staff criticized the business because of its practice of paying them less than half the official minimum wage in the UK, with the business allocating tips to staff to bring their salaries within the law. Most customers, it was argued, do not realize that they are subsidizing a low wage when they give the tip.

Document 11: W. E. B. Du Bois: Racism was the main target of Du Bois's polemics, and he strongly protested against lynching, Jim Crow laws, and discrimination in education and employment. His cause included people of color everywhere, particularly Africans and Asians in colonies. He was a proponent of Pan-Africanism and helped organize several Pan-African Congresses to fight for the independence of African colonies from European powers. Du Bois made several trips to Europe, Africa and Asia. After World War I, he surveyed the experiences of American black soldiers in France and documented widespread prejudice in the United States military.
Document 12: Mexico City: Other popular sites for pop-artist performances include the 3,000-seat Teatro Metropolitan, the 15,000-seat Palacio de los Deportes, and the larger 50,000-seat Foro Sol Stadium, where popular international artists perform on a regular basis. The Cirque du Soleil has held several seasons at the Carpa Santa Fe, in the Santa Fe district in the western part of the city.

Document 13: Hard Rock Cafe: The chain began to expand worldwide in 1982 with locations in (among others) Toronto, Los Angeles, San Francisco, Chicago, Paris, and Berlin. Hard Rock Cafe locations in the United States vary from smaller, more tourist driven markets (Biloxi, Pigeon Forge, Key West, etc.) to large metropolises (Houston, Philadelphia, New York City, Chicago, Boston, Washington, D.C., etc.). Hard Rock Cafe typically does not franchise cafe locations in the United States. All US cafes are corporate owned and operated, except for cafes in Tampa and Four Winds New Buffalo casino. However, in the transition of the Las Vegas Hard Rock Hotel property originally owned and then later sold to Rank by founder Peter Morton, Morton retained hotel naming rights west of the Mississippi. When Morton sold his Las Vegas Hard Rock Hotel to the Morgans Hotel Group, he also sold those naming rights, which then gave rise to two US franchised hotels (without cafes) in Albuquerque and Tulsa. The Albuquerque hotel no longer pays for the Hard Rock rights and reverted to its former name in June 2013. More hotels franchised from Morgan's are planned for Sioux City and Vancouver.
Document 14: First Pan-African Conference: The First Pan-African Conference was held in London from 23 to 25 July 1900 (just prior to the Paris Exhibition of 1900 ``in order to allow tourists of African descent to attend both events '').

Du Bois, with Bishop Alexander Walters of the AME Zion Church taking the chair. Du Bois played a leading role, drafting a letter (`` Address to the Nations of the World'') to European leaders appealing to them to struggle against racism, to grant colonies in Africa and the West Indies the right to self - government and demanding political and other rights for African Americans.
Document 15: Mexico City: The city is also a leading center of popular culture and music. There are a multitude of venues hosting Spanish and foreign-language performers.
