paragraph_text: Alaska has vast energy resources, although its oil reserves have been largely depleted. Major oil and gas reserves were found in the Alaska North Slope (ANS) and Cook Inlet basins, but according to the Energy Information Administration, by February 2014 Alaska had fallen to fourth place in the nation in crude oil production after Texas, North Dakota, and California. Prudhoe Bay on Alaska's North Slope is still the second highest-yielding oil field in the United States, typically producing about 400,000 barrels per day (64,000 m3/d), although by early 2014 North Dakota's Bakken Formation was producing over 900,000 barrels per day (140,000 m3/d). Prudhoe Bay was the largest conventional oil field ever discovered in North America, but was much smaller than Canada's enormous Athabasca oil sands field, which by 2014 was producing about 1,500,000 barrels per day (240,000 m3/d) of unconventional oil, and had hundreds of years of producible reserves at that rate.

paragraph_text: The imperial tanka (also called Sultani Tanka) was officially introduced by the monetary reforms of Muhammad bin Tughluq, the emperor of the Delhi Sultanate, in 1329. It was modeled as representative money, a concept pioneered as paper money by the Mongols in China and Persia. The tanka was minted in copper and brass. Its value was exchanged with gold and silver reserves in the imperial treasury. The currency was introduced due to the shortage of metals. Over time, the tanka was minted in silver. However, chaos followed its launch in the 14th century, leading to the collapse of the Tughluq dynasty. The Tughluqs were succeeded by numerous regional states, notably the Bengal Sultanate, the Bahmani Sultanate and the Gujarat Sultanate. These kingdoms continued to mint the new currency in the name of their own rulers. Even much later under the early modern Mughal Empire, regional currencies were still referred to as tanka / tangka / taka.

paragraph_text: Iran has the second largest proved gas reserves in the world after Russia, with 33.6 trillion cubic metres, and third largest natural gas production in the world after Indonesia, and Russia. It also ranks fourth in oil reserves with an estimated 153,600,000,000 barrels. It is OPEC's 2nd largest oil exporter and is an energy superpower. In 2005, Iran spent US$4 billion on fuel imports, because of contraband and inefficient domestic use. Oil industry output averaged 4 million barrels per day (640,000 m3/d) in 2005, compared with the peak of six million barrels per day reached in 1974. In the early years of the 2000s (decade), industry infrastructure was increasingly inefficient because of technological lags. Few exploratory wells were drilled in 2005.

paragraph_text: The Sarir Field was discovered in southern Cyrenaica during 1961 and is considered to be the largest oil field in Libya, with estimated oil reserves of . Sarir is operated by the Arabian Gulf Oil Company (AGOCO), a subsidiary of the state-owned National Oil Corporation (NOC).

paragraph_text: Religious beliefs in the Eastern Empire and Persia were in flux during the late 6th and early 7th centuries. Judaism was an active proselytising faith, and at least one Arab political leader converted to it.[J] Christianity had active missions competing with the Persians' Zoroastrianism in seeking converts, especially among residents of the Arabian Peninsula. All these strands came together with the emergence of Islam in Arabia during the lifetime of Muhammad (d. 632). After his death, Islamic forces conquered much of the Eastern Empire and Persia, starting with Syria in 634–635 and reaching Egypt in 640–641, Persia between 637 and 642, North Africa in the later 7th century, and the Iberian Peninsula in 711. By 714, Islamic forces controlled much of the peninsula in a region they called Al-Andalus.

paragraph_text: Asphalt/bitumen also occurs in unconsolidated sandstones known as "oil sands" in Alberta, Canada, and the similar "tar sands" in Utah, US. The Canadian province of Alberta has most of the world's reserves of natural bitumen, in three huge deposits covering 142,000 square kilometres (55,000 sq mi), an area larger than England or New York state. These bituminous sands contain 166 billion barrels (26.4×10^9 m3) of commercially established oil reserves, giving Canada the third largest oil reserves in the world. and produce over 2.3 million barrels per day (370×10^3 m3/d) of heavy crude oil and synthetic crude oil. Although historically it was used without refining to pave roads, nearly all of the bitumen is now used as raw material for oil refineries in Canada and the United States.

paragraph_text: Bonneville International Corporation is a media and broadcasting company, wholly owned by The Church of Jesus Christ of Latter-day Saints (LDS Church) through its for-profit arm, Deseret Management Corporation. It began as a radio and TV network in the Triad Center Broadcast House in Salt Lake City, Utah. Bonneville's name alludes to Benjamin Bonneville and the prehistoric Lake Bonneville that once covered much of modern-day Utah, which was named after him.

paragraph_text: Copper has been in use at least 10,000 years, but more than 95% of all copper ever mined and smelted has been extracted since 1900, and more than half was extracted in only the last 24 years. As with many natural resources, the total amount of copper on Earth is vast (around 1014 tons just in the top kilometer of Earth's crust, or about 5 million years' worth at the current rate of extraction). However, only a tiny fraction of these reserves is economically viable, given present-day prices and technologies. Various estimates of existing copper reserves available for mining vary from 25 years to 60 years, depending on core assumptions such as the growth rate. Recycling is a major source of copper in the modern world. Because of these and other factors, the future of copper production and supply is the subject of much debate, including the concept of peak copper, analogous to peak oil.

paragraph_text: King's Castle is an Iron Age enclosed hilltop settlement at the south-western edge of the Mendip Hills near Wells in Somerset, England. Though there are many prehistoric sites in the surrounding area, it remains one of the earliest known settlements in the immediate vicinity of Wells, and may have been a precursor to the present day city. It consists of two or three interlinked sub-enclosures, with what appears to be a field system extending to the east; an unusual layout, the site remains relatively little studied and has not been archaeologically excavated. It is a Scheduled Ancient Monument, and shares its name with the surrounding King's Castle Wood—today a Somerset Wildlife Trust nature reserve—though this name is probably a modern invention.

paragraph_text: 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.

paragraph_text: Oil reserves in Canada were estimated at 172 billion barrels (27 × 10 ^ m) as of the start of 2015. This figure includes the oil sands reserves that are estimated by government regulators to be economically producible at current prices using current technology. According to this figure, Canada's reserves are third only to Venezuela and Saudi Arabia. Over 95% of these reserves are in the oil sands deposits in the province of Alberta. Alberta contains nearly all of Canada's oil sands and much of its conventional oil reserves. The balance is concentrated in several other provinces and territories. Saskatchewan and offshore areas of Newfoundland in particular have substantial oil production and reserves. Alberta has 39% of Canada's remaining conventional oil reserves, offshore Newfoundland 28% and Saskatchewan 27%, but if oil sands are included, Alberta's share is over 98%.

paragraph_text: In the Western world, Persia (or one of its cognates) was historically the common name for Iran. On the Nowruz of 1935, Reza Shah Pahlavi asked foreign delegates to use the term Iran, the endonym of the country, in formal correspondence. Since then, in the Western World, the use of the word ``Iran ''has become more common. This also changed the usage of the terms for Iranian nationality, and the common adjective for citizens of Iran changed from`` Persian'' to ``Iranian ''. In 1959, the government of Mohammad Reza Shah Pahlavi, Reza Shah Pahlavi's son, announced that both`` Persia'' and ``Iran ''could officially be used interchangeably. However the issue is still debated today.

paragraph_text: Saudi Arabian oil was first discovered by the Americans in commercial quantities at Dammam oil well No. 7 in 1938 in what is now modern day Dhahran.

paragraph_text: Based on data from OPEC at the beginning of 2013 the highest proved oil reserves including non-conventional oil deposits are in Venezuela (20% of global reserves), Saudi Arabia (18% of global reserves), Canada (13% of global reserves), and Iran (9%).

paragraph_text: In 530 BC Cyrus the Great, King of the Persian Achaemenid Empire crossed the Hindu-Kush mountains to seek tribute from the tribes of Kamboja, Gandhara and the trans-India region (modern Afghanistan and Pakistan). By 520 BC, during the reign of Darius I of Persia, much of the northwestern subcontinent (present-day eastern Afghanistan and Pakistan) came under the rule of the Persian Achaemenid Empire, as part of the far easternmost territories. The area remained under Persian control for two centuries. During this time India supplied mercenaries to the Persian army then fighting in Greece.

paragraph_text: The proven oil reserves in Saudi Arabia are the second largest in the world, estimated to be 268 billion barrels (43 × 10 ^ m) (Gbbl hereafter), including 2.5 Gbbl in the Saudi -- Kuwaiti neutral zone. They are predominantly found in the Eastern Province. These reserves were the largest in the world until Venezuela announced they had increased their proven reserves to 297 Gbbl in January 2011. The Saudi reserves are about one - fifth of the world's total conventional oil reserves, a large fraction of these reserves comes from a small number of very large oil fields, and past production amounts to 40% of the stated reserves.

paragraph_text: The Videle oil field is an oil field located in Videle, Teleorman County, Romania. It was discovered in 1958 and developed by Petrom. It began production in 1961 and produces oil. The total proven reserves of the Videle oil field are around 300 million barrels (41×10tonnes), and production is centered on .

paragraph_text: Bob Kames (April 21, 1925 – April 9, 2008) was an American musician who specialized in genres such as polka. Kames is credited with developing and popularizing the modern-day version of the song "Dance Little Bird," which is much better known by its more common name, The Chicken Dance. Kames is a member of the Wisconsin Area Music Industry's Hall of Fame.

paragraph_text: The two branches of the Barkazi Dynasty (Translation of Barakzai: sons of Barak) ruled modern day Afghanistan from 1826 to 1973 when the monarchy ended under Musahiban Mohammed Zahir Shah. The Barakzai dynasty was established by Dost Mohammad Khan after the Durrani dynasty of Ahmad Shah Durrani was removed from power. During this era, Afghanistan saw much of its territory lost to the British in the south and east, Persia in the west, and Russia in the north. There were also many conflicts within Afghanistan, including the three major Anglo-Afghan Wars and the 1929 civil war.

paragraph_text: Naturally occurring crude asphalt/bitumen impregnated in sedimentary rock is the prime feed stock for petroleum production from "Oil sands", currently under development in Alberta, Canada. Canada has most of the world's supply of natural asphalt/bitumen, covering 140,000 square kilometres (an area larger than England), giving it the second-largest proven oil reserves in the world. The Athabasca oil sands is the largest asphalt/bitumen deposit in Canada and the only one accessible to surface mining, although recent technological breakthroughs have resulted in deeper deposits becoming producible by in situ methods. Because of oil price increases after 2003, producing bitumen became highly profitable, but as a result of the decline after 2014 it became uneconomic to build new plants again. By 2014, Canadian crude asphalt/bitumen production averaged about 2.3 million barrels (370,000 m3) per day and was projected to rise to 4.4 million barrels (700,000 m3) per day by 2020. The total amount of crude asphalt/bitumen in Alberta which could be extracted is estimated to be about 310 billion barrels (50×10^9 m3), which at a rate of 4,400,000 barrels per day (700,000 m3/d) would last about 200 years.
