Problem: Sichuan:

Sichuan consists of two geographically very distinct parts. The eastern part of the province is mostly within the fertile Sichuan basin (which is shared by Sichuan with Chongqing Municipality). The western Sichuan consists of the numerous mountain ranges forming the easternmost part of the Qinghai-Tibet Plateau, which are known generically as Hengduan Mountains. One of these ranges, Daxue Mountains, contains the highest point of the province Gongga Shan, at 7,556 metres (24,790 ft) above sea level.

Problem: According to the Office for National Statistics, at the 2001 census there were over a million black people in the United Kingdom; 1% of the total population described themselves as "Black Caribbean", 0.8% as "Black African", and 0.2% as "Black other". Britain encouraged the immigration of workers from the Caribbean after World War II; the first symbolic movement was those who came on the ship the Empire Windrush. The preferred official umbrella term is "black and minority ethnic" (BME), but sometimes the term "black" is used on its own, to express unified opposition to racism, as in the Southall Black Sisters, which started with a mainly British Asian constituency, and the National Black Police Association, which has a membership of "African, African-Caribbean and Asian origin".
What percentage of the population was "Black Caribbean"?

Answer: 1%

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Expansive interior light has been a feature of Gothic cathedrals since the first structure was opened. The metaphysics of light in the Middle Ages led to clerical belief in its divinity and the importance of its display in holy settings. Much of this belief was based on the writings of Pseudo-Dionysius, a sixth-century mystic whose book, The Celestial Hierarchy, was popular among monks in France. Pseudo-Dionysius held that all light, even light reflected from metals or streamed through windows, was divine. To promote such faith, the abbot in charge of the Saint-Denis church on the north edge of Paris, the Abbot Suger, encouraged architects remodeling the building to make the interior as bright as possible.
Who held the belief that all light, including light reflected from walls and surfaces was fake?
A: unanswerable

Context and question: The 19th century brought new standards of accuracy and style. In regard to accuracy, observes J.M. Cohen, the policy became "the text, the whole text, and nothing but the text", except for any bawdy passages and the addition of copious explanatory footnotes. In regard to style, the Victorians' aim, achieved through far-reaching metaphrase (literality) or pseudo-metaphrase, was to constantly remind readers that they were reading a foreign classic. An exception was the outstanding translation in this period, Edward FitzGerald's Rubaiyat of Omar Khayyam (1859), which achieved its Oriental flavor largely by using Persian names and discreet Biblical echoes and actually drew little of its material from the Persian original.
What did the Victorians aim to remind the reader of their translations?
Answer: that they were reading a foreign classic

Question: In 1996, a surrogate character mechanism was implemented in Unicode 2.0, so that Unicode was no longer restricted to 16 bits. This increased the Unicode codespace to over a million code points, which allowed for the encoding of many historic scripts (e.g., Egyptian Hieroglyphs) and thousands of rarely used or obsolete characters that had not been anticipated as needing encoding. Among the characters not originally intended for Unicode are rarely used Kanji or Chinese characters, many of which are part of personal and place names, making them rarely used, but much more essential than envisioned in the original architecture of Unicode.
Is there an answer to this question: Why was the Unicode 2.0 codespace increased?

Answer: allowed for the encoding of many historic scripts

Problem: Umayyad Caliphate:

At the time, the Umayyad taxation and administrative practice were perceived as unjust by some Muslims. The Christian and Jewish population had still autonomy; their judicial matters were dealt with in accordance with their own laws and by their own religious heads or their appointees, although they did pay a poll tax for policing to the central state. Muhammad had stated explicitly during his lifetime that abrahamic religious groups (still a majority in times of the Umayyad Caliphate), should be allowed to practice their own religion, provided that they paid the jizya taxation. The welfare state of both the Muslim and the non-Muslim poor started by Umar ibn al Khattab had also continued. Muawiya's wife Maysum (Yazid's mother) was also a Christian. The relations between the Muslims and the Christians in the state were stable in this time. The Umayyads were involved in frequent battles with the Christian Byzantines without being concerned with protecting themselves in Syria, which had remained largely Christian like many other parts of the empire. Prominent positions were held by Christians, some of whom belonged to families that had served in Byzantine governments. The employment of Christians was part of a broader policy of religious assimilation that was necessitated by the presence of large Christian populations in the conquered provinces, as in Syria. This policy also boosted Muawiya's popularity and solidified Syria as his power base.

What religion never held prominent positions in the Caliphate?
