Problem: ASCII:

The inherent ambiguity of many control characters, combined with their historical usage, created problems when transferring "plain text" files between systems. The best example of this is the newline problem on various operating systems. Teletype machines required that a line of text be terminated with both "Carriage Return" (which moves the printhead to the beginning of the line) and "Line Feed" (which advances the paper one line without moving the printhead). The name "Carriage Return" comes from the fact that on a manual typewriter the carriage holding the paper moved while the position where the typebars struck the ribbon remained stationary. The entire carriage had to be pushed (returned) to the right in order to position the left margin of the paper for the next line.

Which advances the paper where the typebars strike the ribbon?

A: unanswerable


Problem: From 1805 to 1847, Detroit was the capital of Michigan (first the territory, then the state). Detroit surrendered without a fight to British troops during the War of 1812 in the Siege of Detroit. The Battle of Frenchtown (January 18–23, 1813) was part of a United States effort to retake the city, and American troops suffered their highest fatalities of any battle in the war. This battle is commemorated at River Raisin National Battlefield Park south of Detroit in Monroe County. Detroit was finally recaptured by the United States later that year.
In which War was Detroit captured by the British?

Answer: War of 1812


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the 19th century, a house near Ephesus in Turkey was found, based on the visions of Anne Catherine Emmerich, an Augustinian nun in Germany. It has since been visited as the House of the Virgin Mary by Roman Catholic pilgrims who consider it the place where Mary lived until her assumption. The Gospel of John states that Mary went to live with the Disciple whom Jesus loved,[Jn 19:27] identified as John the Evangelist.[citation needed] Irenaeus and Eusebius of Caesarea wrote in their histories that John later went to Ephesus, which may provide the basis for the early belief that Mary also lived in Ephesus with John.
With whom is it believed that Mary lived with in Ephesus?
A: John


Context and question: Japan saw the release of the Satellaview, a modem which attached to the Super Famicom's expansion port and connected to the St.GIGA satellite radio station. Users of the Satellaview could download gaming news and specially designed games, which were frequently either remakes of or sequels to older Famicom titles, released in installments. Satellaview signals were broadcast from April 23, 1995 through June 30, 2000. In the United States, the similar but relatively short-lived XBAND allowed users to connect to a network via a dial-up modem to compete against other players around the country.
What kind of games were downloaded on XBAND  to compete in Japan?
Answer: unanswerable


Question: The earliest known use of the phrase Brytish Iles in the English language is dated 1577 in a work by John Dee. Today, this name is seen by some as carrying imperialist overtones although it is still commonly used. Other names used to describe the islands include the Anglo-Celtic Isles, Atlantic archipelago, British-Irish Isles, Britain and Ireland, UK and Ireland, and British Isles and Ireland. Owing to political and national associations with the word British, the Government of Ireland does not use the term British Isles and in documents drawn up jointly between the British and Irish governments, the archipelago is referred to simply as "these islands". Nonetheless, British Isles is still the most widely accepted term for the archipelago.
Is there an answer to this question: What is the earliest English usage of the term Brytish Illes?

Answer: a work by John Dee


Question: Finally, an introduced species may unintentionally injure a species that depends on the species it replaces. In Belgium, Prunus spinosa from Eastern Europe leafs much sooner than its West European counterparts, disrupting the feeding habits of the Thecla betulae butterfly (which feeds on the leaves). Introducing new species often leaves endemic and other local species unable to compete with the exotic species and unable to survive. The exotic organisms may be predators, parasites, or may simply outcompete indigenous species for nutrients, water and light.
Is there an answer to this question: What does introducing new spinosas often do?

Answer:
unanswerable
