Problem: In the Low Middle Ages, Catalan went through a golden age, reaching a peak of maturity and cultural richness. Examples include the work of Majorcan polymath Ramon Llull (1232–1315), the Four Great Chronicles (13th–14th centuries), and the Valencian school of poetry culminating in Ausiàs March (1397–1459). By the 15th century, the city of Valencia had become the sociocultural center of the Crown of Aragon, and Catalan was present all over the Mediterranean world. During this period, the Royal Chancery propagated a highly standardized language. Catalan was widely used as an official language in Sicily until the 15th century, and in Sardinia until the 17th. During this period, the language was what Costa Carreras terms "one of the 'great languages' of medieval Europe".
Until what century was Catalan used as the official language in Sardinia?

Answer: 17th


Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Athanasius knew Greek and admitted not knowing Hebrew [see, e.g., the 39th Festal Letter of St. Athan.]. The Old Testament passages he quotes frequently come from the Septuagint Greek translation. Only rarely did he use other Greek versions (to Aquila once in the Ecthesis, to other versions once or twice on the Psalms), and his knowledge of the Old Testament was limited to the Septuagint. Nonetheless, during his later exile, with no access to a copy of the Scriptures, Athanasius could quote from memory every verse in the Old Testament with a supposed reference to the Trinity without missing any.[citation needed] The combination of Scriptural study and of Greek learning was characteristic of the famous Alexandrian School.
What was not a characteristic of the school?
A: unanswerable


Context and question: The Prussian General Staff developed by Moltke proved to be extremely effective, in contrast to the traditional French school. This was in large part due to the fact that the Prussian General Staff was created to study previous Prussian operations and learn to avoid mistakes. The structure also greatly strengthened Moltke's ability to control large formations spread out over significant distances. The Chief of the General Staff, effectively the commander in chief of the Prussian army, was independent of the minister of war and answered only to the monarch. The French General Staff—along with those of every other European military—was little better than a collection of assistants for the line commanders. This disorganization hampered the French commanders' ability to exercise control of their forces.
Who is essentially considered the commander in chief of the Prussian army?
Answer: The Chief of the General Staff


Question: Historians have divided the history of Cubism into phases. In one scheme, the first phase of Cubism, known as Analytic Cubism, a phrase coined by Juan Gris a posteriori, was both radical and influential as a short but highly significant art movement between 1910 and 1912 in France. A second phase, Synthetic Cubism, remained vital until around 1919, when the Surrealist movement gained popularity. English art historian Douglas Cooper proposed another scheme, describing three phases of Cubism in his book, The Cubist Epoch. According to Cooper there was "Early Cubism", (from 1906 to 1908) when the movement was initially developed in the studios of Picasso and Braque; the second phase being called "High Cubism", (from 1909 to 1914) during which time Juan Gris emerged as an important exponent (after 1911); and finally Cooper referred to "Late Cubism" (from 1914 to 1921) as the last phase of Cubism as a radical avant-garde movement. Douglas Cooper's restrictive use of these terms to distinguish the work of Braque, Picasso, Gris (from 1911) and Léger (to a lesser extent) implied an intentional value judgement.
Is there an answer to this question: What was the second phase of Cubism called? 

Answer: Synthetic Cubism

Howard differed from his Labor predecessor Paul Keating in that he supported traditional Australian institutions like the Monarchy in Australia, the commemoration of ANZAC Day and the design of the Australian flag, but like Keating he pursued privatisation of public utilities and the introduction of a broad based consumption tax (although Keating had dropped support for a GST by the time of his 1993 election victory). Howard's premiership coincided with Al Qaeda's 11 September attacks on the United States. The Howard Government invoked the ANZUS treaty in response to the attacks and supported America's campaigns in Afghanistan and Iraq.
Under what agreement did ANZAC support the US?
A:
unanswerable
