Depopulation, deurbanisation, invasion, and movement of peoples, which had begun in Late Antiquity, continued in the Early Middle Ages. The barbarian invaders, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle Eastonce part of the Eastern Roman Empirecame under the rule of the Caliphate, an Islamic empire, after conquest by Muhammad's successors. Although there were substantial changes in society and political structures, the break with Antiquity was not complete. The still-sizeable Byzantine Empire survived in the east and remained a major power. The empire's law code, the Code of Justinian, was rediscovered in Northern Italy in 1070 and became widely admired later in the Middle Ages. In the West, most kingdoms incorporated the few extant Roman institutions. Monasteries were founded as campaigns to Christianise pagan Europe continued. The Franks, under the Carolingian dynasty, briefly established the Carolingian Empire during the later 8th and early 9th century. It covered much of Western Europe, but later succumbed to the pressures of internal civil wars combined with external invasionsVikings from the north, Magyars from the east, and Saracens from the south.

In what state did barbarian invaders establish kingdoms?
Answer: the Western Roman Empire

Problem: Christianity is the predominant religion of Switzerland (about 71% of resident population and 75% of Swiss citizens), divided between the Catholic Church (38.21% of the population), the Swiss Reformed Church (26.93%), further Protestant churches (2.89%) and other Christian denominations (2.79%). There has been a recent rise in Evangelicalism. Immigration has brought Islam (4.95%) and Eastern Orthodoxy (around 2%) as sizeable minority religions. According to a 2015 poll by Gallup International, 12% of Swiss people self-identified as "convinced atheists."
According to a 2015 Gallup Poll, what percentage of Swiss people are convinced atheists?

Cyprus suffers from a chronic shortage of water. The country relies heavily on rain to provide household water, but in the past 30 years average yearly precipitation has decreased. Between 2001 and 2004, exceptionally heavy annual rainfall pushed water reserves up, with supply exceeding demand, allowing total storage in the island's reservoirs to rise to an all-time high by the start of 2005. However, since then demand has increased annually a result of local population growth, foreigners moving to Cyprus and the number of visiting tourists while supply has fallen as a result of more frequent droughts.
Why has the water supply shrunk in previous years?
more frequent droughts

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.

How long did it take for madaris to spread to smaller cities and towns?
Output: several centuries

Input: Article: Following the discovery of a buffer overflow vulnerability in the Wii version of Twilight Princess, an exploit known as the "Twilight Hack" was developed, allowing the execution of custom code from a Secure Digital (SD) card on the console. A properly designed save file would cause the game to load unsigned code, which could include Executable and Linkable Format (ELF) programs and homebrew Wii applications. Versions 3.3 and 3.4 of the Wii Menu prevented copying exploited save files onto the console until circumvention methods were discovered, and version 4.0 of the Wii Menu patched the vulnerability.

Now answer this question: Which issue of the Wii Menu fixed the issue with Twilight Princess?

Output: 4.0

Problem: In contrast, the Salon Cubists built their reputation primarily by exhibiting regularly at the Salon d'Automne and the Salon des Independants, both major non-academic Salons in Paris. They were inevitably more aware of public response and the need to communicate. Already in 1910 a group began to form which included Metzinger, Gleizes, Delaunay and Leger. They met regularly at Henri le Fauconnier's studio near the Boulevard de Montparnasse. These soirees often included writers such as Guillaume Apollinaire and Andre Salmon. Together with other young artists, the group wanted to emphasise a research into form, in opposition to the Neo-Impressionist emphasis on color.
Which four people usually met at Fauconnier's studio in 1910?
The answer is the following:
Metzinger, Gleizes, Delaunay and Leger
