Problem: In 1562 Francisco de Ibarra headed a personal expedition in search of the mythical cities of Cibola and Quivira; he traveled through the present-day state of Chihuahua. Francisco de Ibarra is thought to have been the first European to see the ruins of Paquime. In 1564 Rodrigo de Rio de Loza, a lieutenant under Francisco de Ibarra, stayed behind after the expedition and found gold at the foot of the mountains of the Sierra Madre Occidental; he founded the first Spanish city in the region, Santa Barbara in 1567 by bringing 400 European families to the settlement. A few years later in 1569 Franciscan missionaries led by Fray Agustin Rodriguez from the coast of Sinaloa and the state of Durango founded the first mission in the state in Valle de San Bartolome (present-day Valle de Allende). Fray Agustin Rodriguez evangelized the native population until 1581. Between 1586 and 1588 a epidemic caused a temporary exodus of the small population in the territory of Nueva Vizcaya.
Through which present-day state did he travel?
The answer is the following: Chihuahua

Elementary and secondary public schools are overseen by the North Carolina Department of Public Instruction. The North Carolina Superintendent of Public Instruction is the secretary of the North Carolina State Board of Education, but the board, rather than the superintendent, holds most of the legal authority for making public education policy. In 2009, the board's chairman also became the "chief executive officer" for the state's school system. North Carolina has 115 public school systems, each of which is overseen by a local school board. A county may have one or more systems within it. The largest school systems in North Carolina are the Wake County Public School System, Charlotte-Mecklenburg Schools, Guilford County Schools, Winston-Salem/Forsyth County Schools, and Cumberland County Schools. In total there are 2,425 public schools in the state, including 99 charter schools. North Carolina Schools were segregated until the Brown v. Board of Education trial and the release of the Pearsall Plan.
Who holds most legal authority for making education policy?
the board

Input: Madrasa
At the beginning of the Caliphate or Islamic Empire, the reliance on courts initially confined sponsorship and scholarly activities to major centres. Within several centuries, the development of Muslim educational institutions such as the madrasah and masjid eventually introduced such activities to provincial towns and dispersed them across the Islamic legal schools and Sufi orders. In addition to religious subjects, they also taught the "rational sciences," as varied as mathematics, astronomy, astrology, geography, alchemy, philosophy, magic, and occultism, depending on the curriculum of the specific institution in question. The madaris, however, were not centres of advanced scientific study; scientific advances in Islam were usually carried out by scholars working under the patronage of royal courts. During this time,[when?] the Caliphate experienced a growth in literacy, having the highest literacy rate of the Middle Ages, comparable to classical Athens' literacy in antiquity but on a much larger scale. The emergence of the maktab and madrasa institutions played a fundamental role in the relatively high literacy rates of the medieval Islamic world.

What group of people had the highest literacy rates during the Middle Ages?
Output: Caliphate

Input: Article: On 6 September 2007, Belgian-based International Polar Foundation unveiled the Princess Elisabeth station, the world's first zero-emissions polar science station in Antarctica to research climate change. Costing $16.3 million, the prefabricated station, which is part of the International Polar Year, was shipped to the South Pole from Belgium by the end of 2008 to monitor the health of the polar regions. Belgian polar explorer Alain Hubert stated: "This base will be the first of its kind to produce zero emissions, making it a unique model of how energy should be used in the Antarctic." Johan Berte is the leader of the station design team and manager of the project which conducts research in climatology, glaciology and microbiology.

Now answer this question: What unique characteristic does the Princess Elizabeth station feature?

Output: zero-emissions

Article: The military history of the American side of the war involved different strategies over the years. The bombing campaigns of the Air Force were tightly controlled by the White House for political reasons, and until 1972 avoided the main Northern cities of Hanoi and Haiphong and concentrated on bombing jungle supply trails, especially the Ho Chi Minh Trail. The most controversial Army commander was William Westmoreland whose strategy involved systematic defeat of all enemy forces in the field, despite heavy American casualties that alienated public opinion back home.

Question: What two northern Vietnamese cities did the US avoid bombing at the outset of the war?
Ans: Hanoi and Haiphong

Input: American Idol
The most popular contestants are usually not revealed in the results show. Instead, typically the three contestants (two in later rounds) who received the lowest number of votes are called to the center of the stage. One of these three is usually sent to safety; however the two remaining are not necessarily the bottom two. The contestant with the fewest votes is then revealed and eliminated from the competition. A montage of the eliminated contestant's time on the show is played and they give their final performance. However, in season six, during the series' first ever Idol Gives Back episode, no contestant was eliminated, but on the following week, two were sent home. Moreover, starting in season eight, the judges may overturn viewers' decision with a "Judges' Save" if they unanimously agree to. "The save" can only be used once, and only up through the top five. In the eighth, ninth, tenth, and fourteenth seasons, a double elimination then took place in the week following the activation of the save, but in the eleventh and thirteenth seasons, a regular single elimination took place. The save was not activated in the twelfth season and consequently, a non-elimination took place in the week after its expiration with the votes then carrying over into the following week.

How many time can the judges save be used each season?
Output:
once
