Problem: British Isles:

As with most of Europe, prehistoric Britain and Ireland were covered with forest and swamp. Clearing began around 6000 BC and accelerated in medieval times. Despite this, Britain retained its primeval forests longer than most of Europe due to a small population and later development of trade and industry, and wood shortages were not a problem until the 17th century. By the 18th century, most of Britain's forests were consumed for shipbuilding or manufacturing charcoal and the nation was forced to import lumber from Scandinavia, North America, and the Baltic. Most forest land in Ireland is maintained by state forestation programmes. Almost all land outside urban areas is farmland. However, relatively large areas of forest remain in east and north Scotland and in southeast England. Oak, elm, ash and beech are amongst the most common trees in England. In Scotland, pine and birch are most common. Natural forests in Ireland are mainly oak, ash, wych elm, birch and pine. Beech and lime, though not native to Ireland, are also common there. Farmland hosts a variety of semi-natural vegetation of grasses and flowering plants. Woods, hedgerows, mountain slopes and marshes host heather, wild grasses, gorse and bracken.

Problem: The ad fontes principle also had many applications. The re-discovery of ancient manuscripts brought a more profound and accurate knowledge of ancient philosophical schools such as Epicureanism, and Neoplatonism, whose Pagan wisdom the humanists, like the Church fathers of old, tended, at least initially, to consider as deriving from divine revelation and thus adaptable to a life of Christian virtue. The line from a drama of Terence, Homo sum, humani nihil a me alienum puto (or with nil for nihil), meaning "I am a human being, I think nothing human alien to me", known since antiquity through the endorsement of Saint Augustine, gained renewed currency as epitomising the humanist attitude. The statement, in a play modeled or borrowed from a (now lost) Greek comedy by Menander, may have originated in a lighthearted vein as a comic rationale for an old man's meddling but it quickly became a proverb and throughout the ages was quoted with a deeper meaning, by Cicero and Saint Augustine, to name a few, and most notably by Seneca. Richard Bauman writes:
Who was the least influential supporter of the ideals of Terence?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Fears decreased when Stalin died in 1953 and Nikita Khruschev emerged as the Soviet Union's new leader. Soon, life in Soviet Armenia began to see rapid improvement. The church, which suffered greatly under Stalin, was revived when Catholicos Vazgen I assumed the duties of his office in 1955. In 1967, a memorial to the victims of the Armenian Genocide was built at the Tsitsernakaberd hill above the Hrazdan gorge in Yerevan. This occurred after mass demonstrations took place on the tragic event's fiftieth anniversary in 1965.
When did Stalin pass away?
A: 1953

Context and question: Hokkien originated from Quanzhou. After the Opium War in 1842, Xiamen (Amoy) became one of the major treaty ports to be opened for trade with the outside world. From mid-19th century onwards, Xiamen slowly developed to become the political and economical center of the Hokkien-speaking region in China. This caused Amoy dialect to gradually replace the position of dialect variants from Quanzhou and Zhangzhou. From mid-19th century until the end of World War II, western diplomats usually learned Amoy Hokkien as the preferred dialect if they were to communicate with the Hokkien-speaking populace in China or South-East Asia. In the 1940s and 1950s, Taiwan also held Amoy Hokkien as its standard and tended to incline itself towards Amoy dialect.
What port became one of the major treaty ports after the Opium War?
Answer: Xiamen

Question: By the 1890s the profound effect of adrenal extracts on many different tissue types had been discovered, setting off a search both for the mechanism of chemical signalling and efforts to exploit these observations for the development of new drugs. The blood pressure raising and vasoconstrictive effects of adrenal extracts were of particular interest to surgeons as hemostatic agents and as treatment for shock, and a number of companies developed products based on adrenal extracts containing varying purities of the active substance. In 1897 John Abel of Johns Hopkins University identified the active principle as epinephrine, which he isolated in an impure state as the sulfate salt. Industrial chemist Jokichi Takamine later developed a method for obtaining epinephrine in a pure state, and licensed the technology to Parke Davis. Parke Davis marketed epinephrine under the trade name Adrenalin. Injected epinephrine proved to be especially efficacious for the acute treatment of asthma attacks, and an inhaled version was sold in the United States until 2011 (Primatene Mist). By 1929 epinephrine had been formulated into an inhaler for use in the treatment of nasal congestion.
Is there an answer to this question: Who developed the method to get epinephrine in it's pure form?

Answer: Jokichi Takamine

Performers who have studied classical music extensively are said to be "classically trained". This training may be from private lessons from instrument or voice teachers or from completion of a formal program offered by a Conservatory, college or university, such as a B.mus. or M.mus. degree (which includes individual lessons from professors). In classical music, "...extensive formal music education and training, often to postgraduate [Master's degree] level" is required.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): To what level is training for classical music often required?
Ah, so..
postgraduate
