Problem: Dissolution of the Soviet Union:

On July 16, 1989, the Popular Front of Azerbaijan held its first congress and elected Abulfaz Elchibey, who would become President, as its Chairman. On August 19, 600,000 protesters jammed Baku’s Lenin Square (now Azadliq Square) to demand the release of political prisoners. In the second half of 1989, weapons were handed out in Nagorno-Karabakh. When Karabakhis got hold of small arms to replace hunting rifles and crossbows, casualties began to mount; bridges were blown up, roads were blockaded, and hostages were taken.

When was Abulfaz Elchibey elected to Chairman of the Popular Front?

Problem: Though based upon Mahayana, Tibeto-Mongolian Buddhism is one of the schools that practice Vajrayana or "Diamond Vehicle" (also referred to as Mantrayāna, Tantrayāna, Tantric Buddhism, or esoteric Buddhism). It accepts all the basic concepts of Mahāyāna, but also includes a vast array of spiritual and physical techniques designed to enhance Buddhist practice. Tantric Buddhism is largely concerned with ritual and meditative practices. One component of the Vajrayāna is harnessing psycho-physical energy through ritual, visualization, physical exercises, and meditation as a means of developing the mind. Using these techniques, it is claimed that a practitioner can achieve Buddhahood in one lifetime, or even as little as three years. In the Tibetan tradition, these practices can include sexual yoga, though only for some very advanced practitioners.
What type of Buddhism is Tibeto-Mongolian based on?

Answer: Mahayana


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
The university's first chancellor was Joseph Gibson Hoyt. Crow secured the university charter from the Missouri General Assembly in 1853, and Eliot was named President of the Board of Trustees. Early on, Eliot solicited support from members of the local business community, including John O'Fallon, but Eliot failed to secure a permanent endowment. Washington University is unusual among major American universities in not having had a prior financial endowment. The institution had no backing of a religious organization, single wealthy patron, or earmarked government support.
In what year was Joseph Gibson Hoyt born?
A: unanswerable


Context and question: Notably, the most broadly influential innovation of 20th-century American tort law was the rule of strict liability for defective products, which originated with judicial glosses on the law of warranty. In 1963, Roger J. Traynor of the Supreme Court of California threw away legal fictions based on warranties and imposed strict liability for defective products as a matter of public policy in the landmark case of Greenman v. Yuba Power Products. The American Law Institute subsequently adopted a slightly different version of the Greenman rule in Section 402A of the Restatement (Second) of Torts, which was published in 1964 and was very influential throughout the United States. Outside the U.S., the rule was adopted by the European Economic Community in the Product Liability Directive of July 1985 by Australia in July 1992 and by Japan in June 1994.
When was the Greenman rule in Section 402A of the Restatement (Second) of Torts published?
Answer: 1964


Question: The most precise timekeeping device of the ancient world was the water clock, or clepsydra, one of which was found in the tomb of Egyptian pharaoh Amenhotep I (1525–1504 BC). They could be used to measure the hours even at night, but required manual upkeep to replenish the flow of water. The Ancient Greeks and the people from Chaldea (southeastern Mesopotamia) regularly maintained timekeeping records as an essential part of their astronomical observations. Arab inventors and engineers in particular made improvements on the use of water clocks up to the Middle Ages. In the 11th century, Chinese inventors and engineers invented the first mechanical clocks driven by an escapement mechanism.
Is there an answer to this question: What was the most accurate clock=like device in Chaldea?

Answer: unanswerable


Question: In the first year, 400 beer houses opened and within eight years there were 46,000 across the country, far outnumbering the combined total of long-established taverns, pubs, inns and hotels. Because it was so easy to obtain permission and the profits could be huge compared to the low cost of gaining permission, the number of beer houses was continuing to rise and in some towns nearly every other house in a street could be a beer house. Finally in 1869 the growth had to be checked by magisterial control and new licensing laws were introduced. Only then was it made harder to get a licence, and the licensing laws which operate today were formulated.
Is there an answer to this question: How many beer houses existed throughout Britain eight years after the passage of the Beer Act?

Answer:
46,000
