Pelayos' plan was to use the Cantabrian mountains as a place of refuge and protection from the invading Moors. He then aimed to regroup the Iberian Peninsula's Christian armies and use the Cantabrian mountains as a springboard from which to regain their lands from the Moors. In the process, after defeating the Moors in the Battle of Covadonga in 722 AD, Pelayos was proclaimed king, thus founding the Christian Kingdom of Asturias and starting the war of Christian reconquest known in Portuguese as the Reconquista Crista.

In which battle did Pelayos defeat the Moors?
Answer: Battle of Covadonga

Problem: In soil, microorganisms that reside in the rhizosphere (a zone that includes the root surface and the soil that adheres to the root after gentle shaking) carry out nitrogen fixation, converting nitrogen gas to nitrogenous compounds. This serves to provide an easily absorbable form of nitrogen for many plants, which cannot fix nitrogen themselves. Many other bacteria are found as symbionts in humans and other organisms. For example, the presence of over 1,000 bacterial species in the normal human gut flora of the intestines can contribute to gut immunity, synthesise vitamins, such as folic acid, vitamin K and biotin, convert sugars to lactic acid (see Lactobacillus), as well as fermenting complex undigestible carbohydrates. The presence of this gut flora also inhibits the growth of potentially pathogenic bacteria (usually through competitive exclusion) and these beneficial bacteria are consequently sold as probiotic dietary supplements.
How does the conversion help the vegetation?
The answer is the following: provide an easily absorbable form of nitrogen

The city's K-12 enrollment in district run schools has dropped in the last five years from 156,211 students in 2010 to 130,104 students in 2015. During the same time period, the enrollment in charter schools has increased from 33,995 students in 2010 to 62,358 students in 2015. This consistent drop in enrollment has led the city to close 24 of its public schools in 2013. During the 2014 school year, the city spent an average of $12,570 per pupil, below the average among comparable urban school districts.
Has public school enrollment dropped or increased in the last 5 years?
dropped

Input: Strasbourg
Unlike most other cities, Strasbourg's collections of European art are divided into several museums according not only to type and area, but also to epoch.

Old master graphic arts until 1871 is displayed in the Cabinet des estampes et dessins. Decorative arts until 1681 ("German period") are displayed in the Musee de l'uvre Notre-Dame, decorative arts from 1681 to 1871 ("French period") are displayed in the Musee des Arts decoratifs. International art (painting, sculpture, graphic arts) and decorative art since 1871 is displayed in the Musee d'art moderne et contemporain. The latter museum also displays the city's photographic library.

Where is the city's photographic library?
Output: Musee d'art moderne et contemporain

Working Title Films has its headquarters in London. London has been the setting for films including Oliver Twist (1948), Scrooge (1951), Peter Pan (1953), The 101 Dalmatians (1961), My Fair Lady (1964), Mary Poppins (1964), Blowup (1966), The Long Good Friday (1980), Notting Hill (1999), Love Actually (2003), V For Vendetta (2005), Sweeney Todd: The Demon Barber Of Fleet Street (2008) and The King's Speech (2010).

Problem: As in the Scheiner system, speeds were expressed in 'degrees'. Originally the sensitivity was written as a fraction with 'tenths' (for example "18/10 DIN"), where the resultant value 1.8 represented the relative base 10 logarithm of the speed. 'Tenths' were later abandoned with DIN 4512:1957-11, and the example above would be written as "18 DIN". The degree symbol was finally dropped with DIN 4512:1961-10. This revision also saw significant changes in the definition of film speeds in order to accommodate then-recent changes in the American ASA PH2.5-1960 standard, so that film speeds of black-and-white negative film effectively would become doubled, that is, a film previously marked as "18 DIN" would now be labeled as "21 DIN" without emulsion changes.
What unit was used in the DIN to express speeds?
The answer is the following:
degrees
