Question: where was the first stone of the city placed in the ground, Context: On 12 December 1911, during the Delhi Durbar, George V, then Emperor of India, along with Queen Mary, his Consort, made the announcement that the capital of the Raj was to be shifted from Calcutta to Delhi, while laying the foundation stone for the Viceroy's residence in the Coronation Park, Kingsway Camp. The foundation stone of New Delhi was laid by King George V and Queen Mary at the site of Delhi Durbar of 1911 at Kingsway Camp on 15 December 1911, during their imperial visit. Large parts of New Delhi were planned by Edwin Lutyens (Sir Edwin from 1918), who first visited Delhi in 1912, and Herbert Baker (Sir Herbert from 1926), both leading 20th-century British architects. The contract was given to Sobha Singh (later Sir Sobha Singh). Construction really began after World War I and was completed by 1931. The city that was later dubbed "Lutyens' Delhi" was inaugurated in ceremonies beginning on 10 February 1931 by Lord Irwin, the Viceroy. Lutyens designed the central administrative area of the city as a testament to Britain's imperial aspirations.

Answer: site of Delhi Durbar of 1911 at Kingsway Camp


Question: Einstein created a way of thinking called a?, Context: It was only the orbit of the planet Mercury that Newton's Law of Gravitation seemed not to fully explain. Some astrophysicists predicted the existence of another planet (Vulcan) that would explain the discrepancies; however, despite some early indications, no such planet could be found. When Albert Einstein formulated his theory of general relativity (GR) he turned his attention to the problem of Mercury's orbit and found that his theory added a correction, which could account for the discrepancy. This was the first time that Newton's Theory of Gravity had been shown to be less correct than an alternative.

Answer: theory


Question: Who's idea was patented first Cassell or Richard Tappin Claridge?, Context: The first British patent for the use of asphalt/bitumen was 'Cassell's patent asphalte or bitumen' in 1834. Then on 25 November 1837, Richard Tappin Claridge patented the use of Seyssel asphalt (patent #7849), for use in asphalte pavement, having seen it employed in France and Belgium when visiting with Frederick Walter Simms, who worked with him on the introduction of asphalt to Britain. Dr T. Lamb Phipson writes that his father, Samuel Ryland Phipson, a friend of Claridge, was also "instrumental in introducing the asphalte pavement (in 1836)". Indeed, mastic pavements had been previously employed at Vauxhall by a competitor of Claridge, but without success.

Answer:
Cassell
