Input: Asphalt
The great majority of asphalt used commercially is obtained from petroleum. Nonetheless, large amounts of asphalt occur in concentrated form in nature. Naturally occurring deposits of asphalt/bitumen are formed from the remains of ancient, microscopic algae (diatoms) and other once-living things. These remains were deposited in the mud on the bottom of the ocean or lake where the organisms lived. Under the heat (above 50 C) and pressure of burial deep in the earth, the remains were transformed into materials such as asphalt/bitumen, kerogen, or petroleum.

How much heat is required for the natural production of asphalt?
Output: above 50 C

Input: Article: In the wake of the United States' economic downturn and the legalization of gambling in adjacent and nearby states (including Delaware, Maryland, New York, and Pennsylvania), four casino closures took place in 2014: the Atlantic Club on January 13; the Showboat on August 31; the Revel, which was Atlantic City's second-newest casino, on September 2; and Trump Plaza, which originally opened in 1984, and was the poorest performing casino in the city, on September 16.

Now answer this question: How many casino closures took place in Atlantic City in 2014?

Article: Outward urban expansion is now prevented by the Metropolitan Green Belt, although the built-up area extends beyond the boundary in places, resulting in a separately defined Greater London Urban Area. Beyond this is the vast London commuter belt. Greater London is split for some purposes into Inner London and Outer London. The city is split by the River Thames into North and South, with an informal central London area in its interior. The coordinates of the nominal centre of London, traditionally considered to be the original Eleanor Cross at Charing Cross near the junction of Trafalgar Square and Whitehall, are approximately 513026N 000739W / 51.50722N 0.12750W / 51.50722; -0.12750.

Question: Where is the centre of London said to be located?
Ans: Eleanor Cross at Charing Cross near the junction of Trafalgar Square and Whitehall

Here is a question about this article: In British English, the word 'asphalt' is used to refer to a mixture of mineral aggregate and asphalt/bitumen (also called tarmac in common parlance). When bitumen is mixed with clay it is usually called asphaltum. The earlier word 'asphaltum' is now archaic and not commonly used.[citation needed] In American English, 'asphalt' is equivalent to the British 'bitumen'. However, 'asphalt' is also commonly used as a shortened form of 'asphalt concrete' (therefore equivalent to the British 'asphalt' or 'tarmac'). In Australian English, bitumen is often used as the generic term for road surfaces. In Canadian English, the word bitumen is used to refer to the vast Canadian deposits of extremely heavy crude oil, while asphalt is used for the oil refinery product used to pave roads and manufacture roof shingles and various waterproofing products. Diluted bitumen (diluted with naphtha to make it flow in pipelines) is known as dilbit in the Canadian petroleum industry, while bitumen "upgraded" to synthetic crude oil is known as syncrude and syncrude blended with bitumen as synbit. Bitumen is still the preferred geological term for naturally occurring deposits of the solid or semi-solid form of petroleum. Bituminous rock is a form of sandstone impregnated with bitumen. The tar sands of Alberta, Canada are a similar material.
What is the answer to this question: With what word in America, is bitumen used interchangeably?
****
So... 'asphalt

Education in Israel is highly valued in the national culture with its historical values dating back to Ancient Israel and was viewed as one fundamental blocks of ancient Israelite life. Israeli culture views higher education as the key to higher mobility and socioeconomic status in Israeli society. The emphasis of education within Israeli society goes to the gulf within the Jewish diaspora from the Renaissance and Enlightenment Movement all the way to the roots of Zionism in the 1880s. Jewish communities in the Levant were the first to introduce compulsory education for which the organized community, not less than the parents, was responsible for the education of the next generation of Jews. With contemporary Jewish culture's strong emphasis, promotion of scholarship and learning and the strong propensity to promote cultivation of intellectual pursuits as well as the nations high university educational attainment rate exemplifies how highly Israeli society values higher education. The Israeli education system has been praised for various reasons, including its high quality and its major role in spurring Israel's economic development and technological boom. Many international business leaders and organizations such as Microsoft founder Bill Gates have praised Israel for its high quality of education in helping spur Israel's economic development. In 2012, the country ranked second among OECD countries (tied with Japan and after Canada) for the percentage of 25- to 64-year-olds that have attained tertiary education with 46 percent compared with the OECD average of 32 percent. In addition, nearly twice as many Israelis aged 5564 held a higher education degree compared to other OECD countries, with 47 percent holding an academic degree compared with the OECD average of 25%. In 2012, the country ranked third in the world in the number of academic degrees per capita (20 percent of the population).
Who praised Israel for its high quality education?

Historically, the name Armenian has come to internationally designate this group of people. It was first used by neighbouring countries of ancient Armenia. The earliest attestations of the exonym Armenia date around the 6th century BC. In his trilingual Behistun Inscription dated to 517 BC, Darius I the Great of Persia refers to Urashtu (in Babylonian) as Armina (in Old Persian; Armina ( ) and Harminuya (in Elamite). In Greek, "Armenians" is attested from about the same time, perhaps the earliest reference being a fragment attributed to Hecataeus of Miletus (476 BC). Xenophon, a Greek general serving in some of the Persian expeditions, describes many aspects of Armenian village life and hospitality in around 401 BC. He relates that the people spoke a language that to his ear sounded like the language of the Persians.
Who described Armenian life in 401 BC?
****
The answer:
Xenophon
