Problem: Madrasa:

Ibn Sīnā refers to the secondary education stage of maktab schooling as a period of specialisation when pupils should begin to acquire manual skills, regardless of their social status. He writes that children after the age of 14 should be allowed to choose and specialise in subjects they have an interest in, whether it was reading, manual skills, literature, preaching, medicine, geometry, trade and commerce, craftsmanship, or any other subject or profession they would be interested in pursuing for a future career. He wrote that this was a transitional stage and that there needs to be flexibility regarding the age in which pupils graduate, as the student's emotional development and chosen subjects need to be taken into account.

What type of skills did Ibn Sina state children should learn in primary education?

A: unanswerable


Problem: 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.
How long has copper been in use?

Answer: at least 10,000 years


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The language possesses five vowels (or six, under the St. Petersburg Phonological School), which are written with different letters depending on whether or not the preceding consonant is palatalized. The consonants typically come in plain vs. palatalized pairs, which are traditionally called hard and soft. (The hard consonants are often velarized, especially before front vowels, as in Irish). The standard language, based on the Moscow dialect, possesses heavy stress and moderate variation in pitch. Stressed vowels are somewhat lengthened, while unstressed vowels tend to be reduced to near-close vowels or an unclear schwa. (See also: vowel reduction in Russian.)
Who says Russian has 6 vowels?
A: St. Petersburg Phonological School


Context and question: In contrast, Botswana has recently been forced to ban trophy hunting following a precipitous wildlife decline. The numbers of antelope plummeted across Botswana, with a resultant decline in predator numbers, while elephant numbers remained stable and hippopotamus numbers rose. According to the government of Botswana, trophy hunting is at least partly to blame for this, but many other factors, such as poaching, drought and habitat loss are also to blame. Uganda recently did the same, arguing that "the share of benefits of sport hunting were lopsided and unlikely to deter poaching or improve [Uganda's] capacity to manage the wildlife reserves."
What other African country has also recently banned trophy hunting?
Answer: Uganda


Question: Executive authority in Bermuda is vested in the monarch and is exercised on her behalf by the Governor. The governor is appointed by the Queen on the advice of the British Government. The current governor is George Fergusson; he was sworn in on 23 May 2012. There is also a Deputy Governor (currently David Arkley JP). Defence and foreign affairs are carried out by the United Kingdom, which also retains responsibility to ensure good government. It must approve any changes to the Constitution of Bermuda. Bermuda is classified as a British Overseas Territory, but it is the oldest British colony. In 1620, a Royal Assent granted Bermuda limited self-governance; its Parliament is the fifth oldest in the world, behind the Parliament of the United Kingdom, the Tynwald of the Isle of Man, the Althing of Iceland, and Sejm of Poland. Of these, only Bermuda's and the Isle of Man's Tynwald have been in continuous existence since 1620.
Is there an answer to this question: Who is currently the governor of Bermuda?

Answer: George Fergusson


Problem: Cubism:

It was against this background of public anger that Jean Metzinger and Albert Gleizes wrote Du "Cubisme" (published by Eugène Figuière in 1912, translated to English and Russian in 1913). Among the works exhibited were Le Fauconnier's vast composition Les Montagnards attaqués par des ours (Mountaineers Attacked by Bears) now at Rhode Island School of Design Museum, Joseph Csaky's Deux Femme, Two Women (a sculpture now lost), in addition to the highly abstract paintings by Kupka, Amorpha (The National Gallery, Prague), and Picabia, La Source, The Spring (Museum of Modern Art, New York).
