The archipelago is formed by high points on the rim of the caldera of a submarine volcano that forms a seamount. The volcano is one part of a range that was formed as part of the same process that formed the floor of the Atlantic, and the Mid-Atlantic Ridge. The top of the seamount has gone through periods of complete submergence, during which its limestone cap was formed by marine organisms, and during the Ice Ages the entire caldera was above sea level, forming an island of approximately two hundred square miles.

The early Islamic literature indicates that the conquest of India was one of the very early ambitions of the Muslims, though it was recognized as a particularly difficult one. After conquering Persia, the Arab Umayyad Caliphate incorporated parts of what are now Afghanistan and Pakistan around 720. The book Chach Nama chronicles the Chacha Dynasty's period, following the demise of the Rai Dynasty and the ascent of Chach of Alor to the throne, down to the Arab conquest by Muhammad bin Qasim in the early 8th century AD, by defeating the last Hindu monarch of Sindh, Raja Dahir.

Natural uranium consists of three major isotopes: uranium-238 (99.28% natural abundance), uranium-235 (0.71%), and uranium-234 (0.0054%). All three are radioactive, emitting alpha particles, with the exception that all three of these isotopes have small probabilities of undergoing spontaneous fission, rather than alpha emission. There are also five other trace isotopes: uranium-239, which is formed when 238U undergoes spontaneous fission, releasing neutrons that are captured by another 238U atom; uranium-237, which is formed when 238U captures a neutron but emits two more, which then decays to neptunium-237; uranium-233, which is formed in the decay chain of that neptunium-237; and finally, uranium-236 and -240, which appear in the decay chain of primordial plutonium-244. It is also expected that thorium-232 should be able to undergo double beta decay, which would produce uranium-232, but this has not yet been observed experimentally.

Another principal tool in the diagnosis of infectious disease is microscopy. Virtually all of the culture techniques discussed above rely, at some point, on microscopic examination for definitive identification of the infectious agent. Microscopy may be carried out with simple instruments, such as the compound light microscope, or with instruments as complex as an electron microscope. Samples obtained from patients may be viewed directly under the light microscope, and can often rapidly lead to identification. Microscopy is often also used in conjunction with biochemical staining techniques, and can be made exquisitely specific when used in combination with antibody based techniques. For example, the use of antibodies made artificially fluorescent (fluorescently labeled antibodies) can be directed to bind to and identify a specific antigens present on a pathogen. A fluorescence microscope is then used to detect fluorescently labeled antibodies bound to internalized antigens within clinical samples or cultured cells. This technique is especially useful in the diagnosis of viral diseases, where the light microscope is incapable of identifying a virus directly.

Carrying a Louis Vuitton backpack filled with old disks and demos to the studio and back, West crafted much of his production for his debut album in less than fifteen minutes at a time. He recorded the remainder of the album in Los Angeles while recovering from the car accident. Once he had completed the album, it was leaked months before its release date. However, West decided to use the opportunity to review the album, and The College Dropout was significantly remixed, remastered, and revised before being released. As a result, certain tracks originally destined for the album were subsequently retracted, among them "Keep the Receipt" with Ol' Dirty Bastard and "The Good, the Bad, and the Ugly" with Consequence. West meticulously refined the production, adding string arrangements, gospel choirs, improved drum programming and new verses. West's perfectionism led The College Dropout to have its release postponed three times from its initial date in August 2003.

Question: In what city did West finish recording his first album?
Answer: Los Angeles.

Louis XIV distrusted the Parisians and moved his court to Versailles in 1682, but his reign also saw an unprecedented flourishing of the arts and sciences in Paris. The Comédie-Française, the Academy of Painting, and the French Academy of Sciences were founded and made their headquarters in the city. To show that the city was safe against attack, he had the city walls demolished, replacing them with Grands Boulevards. To leave monuments to his reign, he built the Collège des Quatre-Nations, Place Vendôme, Place des Victoires, and began Les Invalides.

During the early 2000s, the USAF fumbled several high profile aircraft procurement projects, such as the missteps on the KC-X program. Winslow Wheeler has written that this pattern represents "failures of intellect and – much more importantly – ethics." As a result, the USAF fleet is setting new records for average aircraft age and needs to replace its fleets of fighters, bombers, airborne tankers, and airborne warning aircraft, in an age of restrictive defense budgets. Finally in the midst of scandal and failure in maintaining its nuclear arsenal, the civilian and military leaders of the air force were replaced in 2008.

Southampton was named "fittest city in the UK" in 2006 by Men's Fitness magazine. The results were based on the incidence of heart disease, the amount of junk food and alcohol consumed, and the level of gym membership. In 2007, it had slipped one place behind London, but was still ranked first when it came to the parks and green spaces available for exercise and the amount of television watched by Sotonians was the lowest in the country. Speedway racing took place at Banister Court Stadium in the pre-war era. It returned in the 1940s after WW2 and the Saints operated until the stadium closed down at the end of 1963. A training track operated in the 1950s in the Hamble area.

The reemergence of Cubism coincided with the appearance from about 1917–24 of a coherent body of theoretical writing by Pierre Reverdy, Maurice Raynal and Daniel-Henry Kahnweiler and, among the artists, by Gris, Léger and Gleizes. The occasional return to classicism—figurative work either exclusively or alongside Cubist work—experienced by many artists during this period (called Neoclassicism) has been linked to the tendency to evade the realities of the war and also to the cultural dominance of a classical or Latin image of France during and immediately following the war. Cubism after 1918 can be seen as part of a wide ideological shift towards conservatism in both French society and culture. Yet, Cubism itself remained evolutionary both within the oeuvre of individual artists, such as Gris and Metzinger, and across the work of artists as different from each other as Braque, Léger and Gleizes. Cubism as a publicly debated movement became relatively unified and open to definition. Its theoretical purity made it a gauge against which such diverse tendencies as Realism or Naturalism, Dada, Surrealism and abstraction could be compared.

Question: Name the three artists who were in part resonsible for the reemergence of Cubism between 1917 and 1924.

In 2001, Lee was inducted into the Alabama Academy of Honor. In the same year, Chicago mayor Richard M. Daley initiated a reading program throughout the city's libraries, and chose his favorite book, To Kill a Mockingbird, as the first title of the One City, One Book program. Lee declared that "there is no greater honor the novel could receive". By 2004, the novel had been chosen by 25 communities for variations of the citywide reading program, more than any other novel. David Kipen of the National Endowment of the Arts, who supervised The Big Read, states "people just seem to connect with it. It dredges up things in their own lives, their interactions across racial lines, legal encounters, and childhood. It's just this skeleton key to so many different parts of people's lives, and they cherish it."

In 1935, Reza Shah requested the international community to refer to the country by its native name, Iran. As the New York Times explained at the time, "At the suggestion of the Persian Legation in Berlin, the Tehran government, on the Persian New Year, Nowruz, March 21, 1935, substituted Iran for Persia as the official name of the country." Opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably. Today, both Persia and Iran are used in cultural contexts; although, Iran is the name used officially in political contexts.

Seismology: To better prepare for calamities, Zhang Heng invented a seismometer in 132 CE which provided instant alert to authorities in the capital Luoyang that an earthquake had occurred in a location indicated by a specific cardinal or ordinal direction. Although no tremors could be felt in the capital when Zhang told the court that an earthquake had just occurred in the northwest, a message came soon afterwards that an earthquake had indeed struck 400 km (248 mi) to 500 km (310 mi) northwest of Luoyang (in what is now modern Gansu). Zhang called his device the 'instrument for measuring the seasonal winds and the movements of the Earth' (Houfeng didong yi 候风地动仪), so-named because he and others thought that earthquakes were most likely caused by the enormous compression of trapped air. See Zhang's seismometer for further details.

Along with the rest of South West England, Plymouth has a temperate oceanic climate (Köppen Cfb) which is generally wetter and milder than the rest of England. This means a wide range of exotic plants can be grown. The annual mean temperature is approximately 11 °C (52 °F). Due to the modifying effect of the sea the seasonal range is less than in most other parts of the UK. As a result of this summer highs are lower than its southerly latitude should warrant, but as a contrast the coldest month of February has mean minimum temperatures as mild as between 3 and 4 °C (37 and 39 °F). Snow is rare, not usually equating to more than a few flakes, but there have been exclusions, namely the European winter storms of 2009-10 which, in early January, covered Plymouth in at least 1 inch (2.5 cm) of snow; more on higher ground. Another period of notable snow occurred from 17–19 December 2010 when up to 8 inches (20 cm) of snow fell through the period – though only 2 inches (5.1 cm) would lie at any one time due to melt. Over the 1961–1990 period, annual snowfall accumulation averaged less than 7 cm (3 in) per year. July and August are the warmest months with mean daily maxima over 19 °C (66 °F).
