Question: Problem: Zinc:

Zinc serves a purely structural role in zinc fingers, twists and clusters. Zinc fingers form parts of some transcription factors, which are proteins that recognize DNA base sequences during the replication and transcription of DNA. Each of the nine or ten Zn2+ ions in a zinc finger helps maintain the finger's structure by coordinately binding to four amino acids in the transcription factor. The transcription factor wraps around the DNA helix and uses its fingers to accurately bind to the DNA sequence.

What role does zinc play in fingers, twists and clusters?
---
A: structural


Problem: Despite repeated efforts by the Tajik government to improve and expand health care, the system remains extremely underdeveloped and poor, with severe shortages of medical supplies.

Public expenditure on health was at 1% of the GDP in 2004.

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Though many of the events were outside the traditional time-period of the Middle Ages, the end of the unity of the Western Church (the Protestant Reformation), was one of the distinguishing characteristics of the medieval period. The Catholic Church had long fought against heretic movements, but during the Late Middle Ages, it started to experience demands for reform from within. The first of these came from Oxford professor John Wycliffe in England. Wycliffe held that the Bible should be the only authority in religious questions, and he spoke out against transubstantiation, celibacy and indulgences. In spite of influential supporters among the English aristocracy, such as John of Gaunt, the movement was not allowed to survive. Though Wycliffe himself was left unmolested, his supporters, the Lollards, were eventually suppressed in England.
Who was one of the English aristocrats who supported the Lollard movement?
A: John of Gaunt


Context and question: The Heian period (平安時代, Heian jidai?) is the last division of classical Japanese history, running from 794 to 1185. The period is named after the capital city of Heian-kyō, or modern Kyōto. It is the period in Japanese history when Buddhism, Taoism and other Chinese influences were at their height. The Heian period is also considered the peak of the Japanese imperial court and noted for its art, especially poetry and literature. Although the Imperial House of Japan had power on the surface, the real power was in the hands of the Fujiwara clan, a powerful aristocratic family who had intermarried with the imperial family. Many emperors actually had mothers from the Fujiwara family. Heian (平安?) means "peace" in Japanese.
The Heian period was known for what types of art?
Answer: poetry and literature


Question: In the everyday world, many individuals sought to divine the future, influence it through magic, or seek vengeance with help from "private" diviners. The state-sanctioned taking of auspices was a form of public divination with the intent of ascertaining the will of the gods, not foretelling the future. Secretive consultations between private diviners and their clients were thus suspect. So were divinatory techniques such as astrology when used for illicit, subversive or magical purposes. Astrologers and magicians were officially expelled from Rome at various times, notably in 139 BC and 33 BC. In 16 BC Tiberius expelled them under extreme penalty because an astrologer had predicted his death. "Egyptian rites" were particularly suspect: Augustus banned them within the pomerium to doubtful effect; Tiberius repeated and extended the ban with extreme force in AD 19. Despite several Imperial bans, magic and astrology persisted among all social classes. In the late 1st century AD, Tacitus observed that astrologers "would always be banned and always retained at Rome".
Is there an answer to this question: What action was not to be sought by state diviners?

Answer: foretelling the future


Question: The first semi-permanent inhabitants of regions near Antarctica (areas situated south of the Antarctic Convergence) were British and American sealers who used to spend a year or more on South Georgia, from 1786 onward. During the whaling era, which lasted until 1966, the population of that island varied from over 1,000 in the summer (over 2,000 in some years) to some 200 in the winter. Most of the whalers were Norwegian, with an increasing proportion of Britons. The settlements included Grytviken, Leith Harbour, King Edward Point, Stromness, Husvik, Prince Olav Harbour, Ocean Harbour and Godthul. Managers and other senior officers of the whaling stations often lived together with their families. Among them was the founder of Grytviken, Captain Carl Anton Larsen, a prominent Norwegian whaler and explorer who, along with his family, adopted British citizenship in 1910.
Is there an answer to this question: When did explorer Carl Anton Larsen become a British citizen?

Answer:
Answer: 1910
