QUES: IBM started working on a prototype system loosely based on Codd's concepts as System R in the early 1970s. The first version was ready in 1974/5, and work then started on multi-table systems in which the data could be split so that all of the data for a record (some of which is optional) did not have to be stored in a single large "chunk". Subsequent multi-user versions were tested by customers in 1978 and 1979, by which time a standardized query language SQL[citation needed] had been added. Codd's ideas were establishing themselves as both workable and superior to CODASYL, pushing IBM to develop a true production version of System R, known as SQL/DS, and, later, Database 2 (DB2).

When was IBM's system released?
What is the answer?
ANS: 1974/5

QUES: In October 1810, six months after Fryderyk's birth, the family moved to Warsaw, where his father acquired a post teaching French at the Warsaw Lyceum, then housed in the Saxon Palace. Fryderyk lived with his family in the Palace grounds. The father played the flute and violin; the mother played the piano and gave lessons to boys in the boarding house that the Chopins kept. Chopin was of slight build, and even in early childhood was prone to illnesses.
Where did Frederic live with his family while they were in Warsaw?

ANS: the Palace grounds

Compared to other team sports, the National Football League preseason is very structured. Every NFL team plays exactly four pre-season exhibition games a year, two at home and two away, with the exception of two teams each year who play a fifth game, the Pro Football Hall of Fame Game. These exhibition games, most of which are held in the month of August, are played for the purpose of helping coaches narrow down the roster from the offseason limit of 90 players to the regular-season limit of 53 players. While the scheduling formula is not as rigid for preseason games as they are for the regular season, there are numerous restrictions and traditions that limit the choices of preseason opponents; teams are also restricted on what days and times they can play these games. Split-squad games, a practice common in baseball and hockey, where a team that is scheduled to play two games on the same day splits their team into two squads, are prohibited. The NFL has played exhibition games in Europe, Japan, Canada, Australia (including the American Bowl in 1999) and Mexico to spread the league's popularity (a game of this type was proposed for China but, due to financial and logistical problems, was eventually canceled). The league has tacitly forbidden the playing of non-league opponents, with the last interleague game having come in 1972 and the last game against a team other than an NFL team (the all-NFL rookie College All-Stars) was held in 1976. Exhibition games are quite unpopular with many fans, who resent having to pay regular-season prices for two home exhibition games as part of a season-ticket package. Numerous lawsuits have been brought by fans and classes of fans against the NFL or its member teams regarding this practice, but none have been successful in halting it.[citation needed] The Pro Bowl, traditionally played after the end of the NFL season (since 2011 is played the week prior to the Super Bowl), is also considered an exhibition game.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many preseason exhibition games does an NFL team play?
Ah, so.. four

Question: The World Bank collects a range of data on corruption, including survey responses from over 100,000 firms worldwide and a set of indicators of governance and institutional quality. Moreover, one of the six dimensions of governance measured by the Worldwide Governance Indicators is Control of Corruption, which is defined as "the extent to which power is exercised for private gain, including both petty and grand forms of corruption, as well as 'capture' of the state by elites and private interests." While the definition itself is fairly precise, the data aggregated into the Worldwide Governance Indicators is based on any available polling: questions range from "is corruption a serious problem?" to measures of public access to information, and not consistent across countries. Despite these weaknesses, the global coverage of these datasets has led to their widespread adoption, most notably by the Millennium Challenge Corporation.
Try to answer this question if possible: Which organization is most notable for adopting the global coverage of these studies?
Answer: Millennium Challenge Corporation

Input: Read this: Old English nouns had grammatical gender, a feature absent in modern English, which uses only natural gender. For example, the words sunne ("sun"), mona ("moon") and wif ("woman/wife") were respectively feminine, masculine and neuter; this is reflected, among other things, in the form of the definite article used with these nouns: seo sunne ("the sun"), se mona ("the moon"), t wif ("the woman/wife"). Pronoun usage could reflect either natural or grammatical gender, when those conflicted (as in the case of wif, a neuter noun referring to a female person).
Question: what did not have a gender in Old English?

Output:
unanswerable
