Document 2: Royal Institute of British Architects: In 2004, the two institutions created the Architecture Gallery (Room 128) at the V&A showing artefacts from the collections of both institutions, this was the first permanent gallery devoted to architecture in the UK. The adjacent Architecture Exhibition Space (Room 128a) is used for temporary displays related to architecture. Both spaces were designed by Gareth Hoskins Architects. At the same time the RIBA Library Drawing and Archives Collections moved from 21 Portman Place to new facilities in the Henry Cole Wing at the V&A. Under the Partnership new study rooms were opened where members of the public could view items from the RIBA and V&A architectural collections under the supervision of curatorial staff. These and the nearby education room were designed by Wright & Wright Architects.
Document 3: Pub: Until the 1970s most of the larger pubs also featured an off-sales counter or attached shop for the sales of beers, wines and spirits for home consumption. In the 1970s the newly built supermarkets and high street chain stores or off-licences undercut the pub prices to such a degree that within ten years all but a handful of pubs had closed their off-sale counters, which had often been referred to colloquially as the jug and bottle.
Document 4: London: London is home to many museums, galleries, and other institutions, many of which are free of admission charges and are major tourist attractions as well as playing a research role. The first of these to be established was the British Museum in Bloomsbury, in 1753. Originally containing antiquities, natural history specimens and the national library, the museum now has 7 million artefacts from around the globe. In 1824 the National Gallery was founded to house the British national collection of Western paintings; this now occupies a prominent position in Trafalgar Square.
Document 5: The Woman Taken in Adultery (Rembrandt): The Woman Taken in Adultery is a painting of 1644 by Rembrandt, bought by the National Gallery, London in 1824, as one of their foundation batch of paintings. It is in oil on oak, and 83.8 x 65.4 cm.
Document 6: British Empire: Though Britain and the empire emerged victorious from the Second World War, the effects of the conflict were profound, both at home and abroad. Much of Europe, a continent that had dominated the world for several centuries, was in ruins, and host to the armies of the United States and the Soviet Union, who now held the balance of global power. Britain was left essentially bankrupt, with insolvency only averted in 1946 after the negotiation of a $US 4.33 billion loan from the United States, the last instalment of which was repaid in 2006. At the same time, anti-colonial movements were on the rise in the colonies of European nations. The situation was complicated further by the increasing Cold War rivalry of the United States and the Soviet Union. In principle, both nations were opposed to European colonialism. In practice, however, American anti-communism prevailed over anti-imperialism, and therefore the United States supported the continued existence of the British Empire to keep Communist expansion in check. The "wind of change" ultimately meant that the British Empire's days were numbered, and on the whole, Britain adopted a policy of peaceful disengagement from its colonies once stable, non-Communist governments were established to assume power. This was in contrast to other European powers such as France and Portugal, which waged costly and ultimately unsuccessful wars to keep their empires intact. Between 1945 and 1965, the number of people under British rule outside the UK itself fell from 700 million to five million, three million of whom were in Hong Kong.
Document 7: Micro gallery: A micro gallery was a computer-based guide to archives and museum collections, first developed for the collections at the National Gallery in London, UK It took three years to develop by the company Cognitive Applications, and opened in July 1991 as part of the facilities in the Sainsbury Wing. Visitors could use the system to determine which pictures they would like to see in the gallery. It was possible to print out personalised information for use during the visit. The Micro Gallery ran for 14 years and a CD-ROM with similar facilities was produced.
Document 8: Milkman joke: In English-speaking culture, a milkman joke is a class of joke exploiting fear of adultery and mistaken paternity. This class of jokes has its roots in the early part of the 20th century, prior to the regular availability of milk in supermarkets. At that time, milk in glass bottles was delivered directly to customers' houses by milkmen, generally in the morning (at which time empty bottles were also collected). Men were commonly the main financial supporters of their families, and a man's wife tended to remain at home to care for their children and home. As the milkman would visit the home at a time when the husband would be away at work, this created an opportune situation for adultery.
Document 9: Self-portrait by Judith Leyster: Self-portrait by Judith Leyster is an Dutch Golden Age painting in oils in the collection of the National Gallery of Art that was offered in 1633 as a masterpiece to the Haarlem Guild of St. Luke. It was attributed for centuries to Frans Hals and was only properly attributed to Judith Leyster upon acquisition by the museum in 1949. The style is indeed comparable to that of Hals, Haarlem's most famous portraitist.
Document 10: New Delhi: New Delhi is home to several historic sites and museums. The National Museum which began with an exhibition of Indian art and artefacts at the Royal Academy in London in the winter of 1947–48 was later at the end was shown at the Rashtrapati Bhawan in 1949. Later it was to form a permanent National Museum. On 15 August 1949, the National Museum was formally inaugurated and currently has 200,000 works of art, both of Indian and foreign origin, covering over 5,000 years.
Document 11: Milk: As an agricultural product, milk is extracted from non-human mammals during or soon after pregnancy. Dairy farms produced about 730 million tonnes of milk in 2011, from 260 million dairy cows. India is the world's largest producer of milk, and is the leading exporter of skimmed milk powder, yet it exports few other milk products. The ever increasing rise in domestic demand for dairy products and a large demand - supply gap could lead to India being a net importer of dairy products in the future. The United States, India, China and Brazil are the world's largest exporters of milk and milk products. China and Russia were the world's largest importers of milk and milk products until 2016 when both countries became self - sufficient, contributing to a worldwide glut of milk.
Document 12: British Empire: By the start of the 20th century, Germany and the United States challenged Britain's economic lead. Subsequent military and economic tensions between Britain and Germany were major causes of the First World War, during which Britain relied heavily upon its empire. The conflict placed enormous strain on the military, financial and manpower resources of Britain. Although the British Empire achieved its largest territorial extent immediately after World War I, Britain was no longer the world's pre-eminent industrial or military power. In the Second World War, Britain's colonies in South-East Asia were occupied by Imperial Japan. Despite the final victory of Britain and its allies, the damage to British prestige helped to accelerate the decline of the empire. India, Britain's most valuable and populous possession, achieved independence as part of a larger decolonisation movement in which Britain granted independence to most territories of the Empire. The transfer of Hong Kong to China in 1997 marked for many the end of the British Empire. Fourteen overseas territories remain under British sovereignty. After independence, many former British colonies joined the Commonwealth of Nations, a free association of independent states. The United Kingdom is now one of 16 Commonwealth nations, a grouping known informally as the Commonwealth realms, that share one monarch—Queen Elizabeth II.
Document 13: The Storm on the Sea of Galilee: The Storm on the Sea of Galilee is a 1633 painting by the Dutch Golden Age painter Rembrandt van Rijn. It was previously in the Isabella Stewart Gardner Museum in Boston, but was stolen in 1990 and remains missing. The painting depicts the miracle of Jesus calming the storm on the Sea of Galilee, specifically as it is described in the fourth chapter of the Gospel of Mark. It is Rembrandt's only seascape.
Document 14: A Woman Drinking with Two Men: A Woman Drinking with Two Men is a 1658 painting by Pieter de Hooch, an example of Dutch Golden Age painting and is part of the collection of the National Gallery, London.
