Problem: National Archives and Records Administration:

Archival descriptions of the permanent holdings of the federal government in the custody of NARA are stored in Archival Research Catalog (ARC). The archival descriptions include information on traditional paper holdings, electronic records, and artifacts. As of December 2012, the catalog consisted of about 10 billion logical data records describing 527,000 artifacts and encompassing 81% of NARA's records. There are also 922,000 digital copies of already digitized materials.

How many catalogs sent to people each year could actually be digitized instead?

A: unanswerable


Problem: Despite changing family roles during adolescence, the home environment and parents are still important for the behaviors and choices of adolescents. Adolescents who have a good relationship with their parents are less likely to engage in various risk behaviors, such as smoking, drinking, fighting, and/or unprotected sexual intercourse. In addition, parents influence the education of adolescence. A study conducted by Adalbjarnardottir and Blondal (2009) showed that adolescents at the age of 14 who identify their parents as authoritative figures are more likely to complete secondary education by the age of 22—as support and encouragement from an authoritative parent motivates the adolescence to complete schooling to avoid disappointing that parent.
Are adolescents that have a good relationship with their parents more or less likely to smoke, drink, fight, or engage in unprotected sex?

Answer: less likely


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Opera debuted in 1996; it has never achieved widespread use, having less than 2% browser usage share as of February 2012 according to Net Applications. Its Opera-mini version has an additive share, in April 2011 amounting to 1.1% of overall browser use, but focused on the fast-growing mobile phone web browser market, being preinstalled on over 40 million phones. It is also available on several other embedded systems, including Nintendo's Wii video game console.
When was the Nintendo Wii introduced?
A: unanswerable


Context and question: Formal discipline is administered by congregation elders. When a baptized member is accused of committing a serious sin—usually cases of sexual misconduct or charges of apostasy for disputing Jehovah's Witness doctrines—a judicial committee is formed to determine guilt, provide help and possibly administer discipline. Disfellowshipping, a form of shunning, is the strongest form of discipline, administered to an offender deemed unrepentant. Contact with disfellowshipped individuals is limited to direct family members living in the same home, and with congregation elders who may invite disfellowshipped persons to apply for reinstatement; formal business dealings may continue if contractually or financially obliged. Witnesses are taught that avoiding social and spiritual interaction with disfellowshipped individuals keeps the congregation free from immoral influence and that "losing precious fellowship with loved ones may help [the shunned individual] to come 'to his senses,' see the seriousness of his wrong, and take steps to return to Jehovah." The practice of shunning may also serve to deter other members from dissident behavior. Members who disassociate (formally resign) are described in Watch Tower Society literature as wicked and are also shunned. Expelled individuals may eventually be reinstated to the congregation if deemed repentant by elders in the congregation in which the disfellowshipping was enforced. Reproof is a lesser form of discipline given formally by a judicial committee to a baptized Witness who is considered repentant of serious sin; the reproved person temporarily loses conspicuous privileges of service, but suffers no restriction of social or spiritual fellowship. Marking, a curtailing of social but not spiritual fellowship, is practiced if a baptized member persists in a course of action regarded as a violation of Bible principles but not a serious sin.[note 4]
Who administers formal discipline?
Answer: congregation elders


Question: In 1911 arsphenamine, the first synthetic anti-infective drug, was developed by Paul Ehrlich and chemist Alfred Bertheim of the Institute of Experimental Therapy in Berlin. The drug was given the commercial name Salvarsan. Ehrlich, noting both the general toxicity of arsenic and the selective absorption of certain dyes by bacteria, hypothesized that an arsenic-containing dye with similar selective absorption properties could be used to treat bacterial infections. Arsphenamine was prepared as part of a campaign to synthesize a series of such compounds, and found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to that time was incurable and led inexorably to severe skin ulceration, neurological damage, and death.[citation needed]
Is there an answer to this question: In what year was arsphenamine discovered?

Answer: 1911


Problem: A cappella:

In July 1943, as a result of the American Federation of Musicians boycott of US recording studios, the a cappella vocal group The Song Spinners had a best-seller with "Comin' In On A Wing And A Prayer". In the 1950s several recording groups, notably The Hi-Los and the Four Freshmen, introduced complex jazz harmonies to a cappella performances. The King's Singers are credited with promoting interest in small-group a cappella performances in the 1960s. In 1983 an a cappella group known as The Flying Pickets had a Christmas 'number one' in the UK with a cover of Yazoo's (known in the US as Yaz) "Only You". A cappella music attained renewed prominence from the late 1980s onward, spurred by the success of Top 40 recordings by artists such as The Manhattan Transfer, Bobby McFerrin, Huey Lewis and the News, All-4-One, The Nylons, Backstreet Boys and Boyz II Men.[citation needed]
