Article: 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 (26.410^9 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 (37010^3 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.

Question: Besides occurrences in Canada, where in the US is asphalt found?
Ans: Utah

Here is a question about this article: The air offensive against the RAF and British industry failed to have the desired effect. More might have been achieved had the OKL exploited their enemy's weak spot, the vulnerability of British sea communications. The Allies did so later when Bomber Command attacked rail communications and the United States Army Air Forces targeted oil, but that would have required an economic-industrial analysis of which the Luftwaffe was incapable. The OKL instead sought clusters of targets that suited the latest policy (which changed frequently), and disputes within the leadership were about tactics rather than strategy. Though militarily ineffective, the Blitz caused enormous damage to Britain's infrastructure and housing stock. It cost around 41,000 lives, and may have injured another 139,000.
What is the answer to this question: What was the Luftwaffe incapable of doing?
****
So... an economic-industrial analysis

The problem: Answer a question about this article:
Whitehead makes the startling observation that "life is comparatively deficient in survival value." If humans can only exist for about a hundred years, and rocks for eight hundred million, then one is forced to ask why complex organisms ever evolved in the first place; as Whitehead humorously notes, "they certainly did not appear because they were better at that game than the rocks around them." He then observes that the mark of higher forms of life is that they are actively engaged in modifying their environment, an activity which he theorizes is directed toward the three-fold goal of living, living well, and living better. In other words, Whitehead sees life as directed toward the purpose of increasing its own satisfaction. Without such a goal, he sees the rise of life as totally unintelligible.
What did Whitehead believe was the fundamental purpose of life?
****
The answer: increasing its own satisfaction

Problem: Please answer a question about the following article about Hyderabad:
In the past, Qutb Shahi rulers and Nizams attracted artists, architects and men of letters from different parts of the world through patronage. The resulting ethnic mix popularised cultural events such as mushairas (poetic symposia). The Qutb Shahi dynasty particularly encouraged the growth of Deccani Urdu literature leading to works such as the Deccani Masnavi and Diwan poetry, which are among the earliest available manuscripts in Urdu. Lazzat Un Nisa, a book compiled in the 15th century at Qutb Shahi courts, contains erotic paintings with diagrams for secret medicines and stimulants in the eastern form of ancient sexual arts. The reign of the Nizams saw many literary reforms and the introduction of Urdu as a language of court, administration and education. In 1824, a collection of Urdu Ghazal poetry, named Gulzar-e-Mahlaqa, authored by Mah Laqa Baithe first female Urdu poet to produce a Diwanwas published in Hyderabad.
Which dynasty supported the Deccani Urdu literature movement?
A: The Qutb Shahi dynasty

In the 5th-century Ravenna, the capital of the Western Roman Empire, became the center of late Roman mosaic art. The Mausoleum of Galla Placidia was decorated with mosaics of high artistic quality in 425430. The vaults of the small, cross-shaped structure are clad with mosaics on blue background. The central motif above the crossing is a golden cross in the middle of the starry sky. Another great building established by Galla Placidia was the church of San Giovanni Evangelista. She erected it in fulfillment of a vow that she made having escaped from a deadly storm in 425 on the sea voyage from Constantinople to Ravenna. The mosaics depicted the storm, portraits of members of the western and eastern imperial family and the bishop of Ravenna, Peter Chrysologus. They are known only from Renaissance sources because almost all were destroyed in 1747.

Why did Galla Placidia erect the church of San Giovanni Evangelista?
Answer: fulfillment of a vow

Unicode has the explicit aim of transcending the limitations of traditional character encodings, such as those defined by the ISO 8859 standard, which find wide usage in various countries of the world but remain largely incompatible with each other. Many traditional character encodings share a common problem in that they allow bilingual computer processing (usually using Latin characters and the local script), but not multilingual computer processing (computer processing of arbitrary scripts mixed with each other).
What is the major limitation of traditional character encodings?
wide usage in various countries of the world but remain largely incompatible with each other
