The design architecture of USB is asymmetrical in its topology, consisting of a host, a multitude of downstream USB ports, and multiple peripheral devices connected in a tiered-star topology. Additional USB hubs may be included in the tiers, allowing branching into a tree structure with up to five tier levels. A USB host may implement multiple host controllers and each host controller may provide one or more USB ports. Up to 127 devices, including hub devices if present, may be connected to a single host controller. USB devices are linked in series through hubs. One hubbuilt into the host controlleris the root hub.
How many USB ports may a host controller provide?
****
The answer: one or more USB ports

Although the Arenafootball2 league played its tenth season in 2009, a conference call in December 2008 resulted in enough votes from owners and cooperation from the AFLPA for the AFL to suspend the entire 2009 season in order to create "a long-term plan to improve its economic model". In doing so, the AFL became the second sports league to cancel an entire season, after the National Hockey League cancelled the 2004-05 season because of a lockout. The AFL also became the third sports league to lose its postseason (the first being Major League Baseball, which lost its postseason in 1994 because of a strike). Efforts to reformat the league's business model were placed under the leadership of Columbus Destroyers owner Jim Renacci and interim commissioner Policy.
In what month and year was it decided to suspend the 2009 Arena Football League season?
****
The answer: December 2008

The problem: Answer a question about this article:
The product claimed to be the strongest beer made is Schorschbrau's 2011 Schorschbock 57 with 57,5%. It was preceded by The End of History, a 55% Belgian ale, made by BrewDog in 2010. The same company had previously made Sink The Bismarck!, a 41% abv IPA, and Tactical Nuclear Penguin, a 32% abv Imperial stout. Each of these beers are made using the eisbock method of fractional freezing, in which a strong ale is partially frozen and the ice is repeatedly removed, until the desired strength is reached, a process that may class the product as spirits rather than beer. The German brewery Schorschbrau's Schorschbock, a 31% abv eisbock, and Hair of the Dog's Dave, a 29% abv barley wine made in 1994, used the same fractional freezing method. A 60% abv blend of beer with whiskey was jokingly claimed as the strongest beer by a Dutch brewery in July 2010.
What is a strong ale called when it is frozen partially, and then the ice is removed again and again?
****
The answer: fractional freezing

When a historic document survives only in translation, the original having been lost, researchers sometimes undertake back-translation in an effort to reconstruct the original text. An example involves the novel The Saragossa Manuscript by the Polish aristocrat Jan Potocki (17611815), who wrote the novel in French and anonymously published fragments in 1804 and 181314. Portions of the original French-language manuscript were subsequently lost; however, the missing fragments survived in a Polish translation that was made by Edmund Chojecki in 1847 from a complete French copy, now lost. French-language versions of the complete Saragossa Manuscript have since been produced, based on extant French-language fragments and on French-language versions that have been back-translated from Chojecki's Polish version.
What do researchers use back-translation to try to reconstruct when a document survives only in translation?
****
The answer:
the original text
