Problem: Tibet:

Although spoken Tibetan varies according to the region, the written language, based on Classical Tibetan, is consistent throughout. This is probably due to the long-standing influence of the Tibetan empire, whose rule embraced (and extended at times far beyond) the present Tibetan linguistic area, which runs from northern Pakistan in the west to Yunnan and Sichuan in the east, and from north of Qinghai Lake south as far as Bhutan. The Tibetan language has its own script which it shares with Ladakhi and Dzongkha, and which is derived from the ancient Indian Brahmi script.

What runs from northern Pakistan to Ladakhi?

Problem: The rule of law is the legal principle that law should govern a nation, as opposed to being governed by arbitrary decisions of individual government officials. It primarily refers to the influence and authority of law within society, particularly as a constraint upon behaviour, including behaviour of government officials. The phrase can be traced back to 16th century Britain, and in the following century the Scottish theologian Samuel Rutherford used the phrase in his argument against the divine right of kings. The rule of law was further popularized in the 19th century by British jurist A. V. Dicey. The concept, if not the phrase, was familiar to ancient philosophers such as Aristotle, who wrote "Law should govern".
Which Scottish theologian is first credited with using the phrase "rule of law"?

Answer: Samuel Rutherford

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
After the expulsion of the German population ethnic Russians, Belarusians, and Ukrainians were settled in the northern part. In the Soviet part of the region, a policy of eliminating all remnants of German history was pursued. All German place names were replaced by new Russian names. The exclave was a military zone, which was closed to foreigners; Soviet citizens could only enter with special permission. In 1967 the remnants of Konigsberg Castle were demolished on the orders of Leonid Brezhnev to make way for a new "House of the Soviets".
In what year did Leonid Brezhnev come to power?
A: unanswerable

Question: In 1644, Rene Descartes theorized that pain was a disturbance that passed down along nerve fibers until the disturbance reached the brain, a development that transformed the perception of pain from a spiritual, mystical experience to a physical, mechanical sensation[citation needed]. Descartes's work, along with Avicenna's, prefigured the 19th-century development of specificity theory. Specificity theory saw pain as "a specific sensation, with its own sensory apparatus independent of touch and other senses". Another theory that came to prominence in the 18th and 19th centuries was intensive theory, which conceived of pain not as a unique sensory modality, but an emotional state produced by stronger than normal stimuli such as intense light, pressure or temperature. By the mid-1890s, specificity was backed mostly by physiologists and physicians, and the intensive theory was mostly backed by psychologists. However, after a series of clinical observations by Henry Head and experiments by Max von Frey, the psychologists migrated to specificity almost en masse, and by century's end, most textbooks on physiology and psychology were presenting pain specificity as fact.
Is there an answer to this question: What did Henry von Frey and Max Head make?

Problem: Eritrea:

Lions are said to inhabit the mountains of the Gash-Barka Region. There is also a small population of elephants that roam in some parts of the country. Dik-diks can also be found in many areas. The endangered African wild ass can be seen in Denakalia Region. Other local wildlife include bushbucks, duikers, greater kudus, klipspringers, African leopards, oryxs and crocodiles., The spotted hyena is widespread and fairly common. Between 1955 and 2001 there were no reported sightings of elephant herds, and they are thought to have fallen victim to the war of independence. In December 2001 a herd of about 30, including 10 juveniles, was observed in the vicinity of the Gash River. The elephants seemed to have formed a symbiotic relationship with olive baboons, with the baboons using the water holes dug by the elephants, while the elephants use the tree-top baboons as an early warning system.

In what year did the war of independence end?
