Problem: Under the Capetian dynasty France slowly began to expand its authority over the nobility, growing out of the Île-de-France to exert control over more of the country in the 11th and 12th centuries. They faced a powerful rival in the Dukes of Normandy, who in 1066 under William the Conqueror (duke 1035–1087), conquered England (r. 1066–87) and created a cross-channel empire that lasted, in various forms, throughout the rest of the Middle Ages. Normans also settled in Sicily and southern Italy, when Robert Guiscard (d. 1085) landed there in 1059 and established a duchy that later became the Kingdom of Sicily. Under the Angevin dynasty of Henry II (r. 1154–89) and his son Richard I (r. 1189–99), the kings of England ruled over England and large areas of France,[W] brought to the family by Henry II's marriage to Eleanor of Aquitaine (d. 1204), heiress to much of southern France.[X] Richard's younger brother John (r. 1199–1216) lost Normandy and the rest of the northern French possessions in 1204 to the French King Philip II Augustus (r. 1180–1223). This led to dissension among the English nobility, while John's financial exactions to pay for his unsuccessful attempts to regain Normandy led in 1215 to Magna Carta, a charter that confirmed the rights and privileges of free men in England. Under Henry III (r. 1216–72), John's son, further concessions were made to the nobility, and royal power was diminished. The French monarchy continued to make gains against the nobility during the late 12th and 13th centuries, bringing more territories within the kingdom under their personal rule and centralising the royal administration. Under Louis IX (r. 1226–70), royal prestige rose to new heights as Louis served as a mediator for most of Europe.[Y]

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
On 1 February 1908, the king Dom Carlos I of Portugal and his heir apparent, Prince Royal Dom Luís Filipe, Duke of Braganza, were murdered in Lisbon. Under his rule, Portugal had twice been declared bankrupt – on 14 June 1892, and again on 10 May 1902 – causing social turmoil, economic disturbances, protests, revolts and criticism of the monarchy. Manuel II of Portugal became the new king, but was eventually overthrown by the 5 October 1910 revolution, which abolished the regime and instated republicanism in Portugal. Political instability and economic weaknesses were fertile ground for chaos and unrest during the Portuguese First Republic. These conditions would lead to the failed Monarchy of the North, 28 May 1926 coup d'état, and the creation of the National Dictatorship (Ditadura Nacional).
On what day were King Dom Carlos I and and his heir, Prince Royal Dom Luis Filipe, Duke of Braganza, murdered?
A: 1 February 1908

Question: Since the Spanish transition to democracy (1975–1982), Catalan has been institutionalizated as an official language, language of education, and language of mass media; all of which have contributed to its increased prestige. In Catalonia, there is no parallel of a large, bilingual, European, non-state speech community. The teaching of Catalan is mandatory in all schools, but it is possible to use Spanish for studying in the public education system of Catalonia in two situations, if the teacher assigned to a class chooses to use Spanish, or during the learning process of one or some recently arrived students.  There is also some intergenerational shift towards Catalan.
Is there an answer to this question: Besides as an official  and an educational language, where else is Catalan the prefered language?

Answer: mass media


Problem: A cappella:

The polyphony of Christian a cappella music began to develop in Europe around the late 15th century, with compositions by Josquin des Prez. The early a cappella polyphonies may have had an accompanying instrument, although this instrument would merely double the singers' parts and was not independent. By the 16th century, a cappella polyphony had further developed, but gradually, the cantata began to take the place of a cappella forms. 16th century a cappella polyphony, nonetheless, continued to influence church composers throughout this period and to the present day. Recent evidence has shown that some of the early pieces by Palestrina, such as what was written for the Sistine Chapel was intended to be accompanied by an organ "doubling" some or all of the voices. Such is seen in the life of Palestrina becoming a major influence on Bach, most notably in the aforementioned Mass in B Minor. Other composers that utilized the a cappella style, if only for the occasional piece, were Claudio Monteverdi and his masterpiece, Lagrime d'amante al sepolcro dell'amata (A lover's tears at his beloved's grave), which was composed in 1610, and Andrea Gabrieli when upon his death it was discovered many choral pieces, one of which was in the unaccompanied style. Learning from the preceding two composeres, Heinrich Schütz utilized the a cappella style in numerous pieces, chief among these were the pieces in the oratorio style, which were traditionally performed during the Easter week and dealt with the religious subject matter of that week, such as Christ's suffering and the Passion. Five of Schutz's Historien were Easter pieces, and of these the latter three, which dealt with the passion from three different viewpoints, those of Matthew, Luke and John, were all done a cappella style. This was a near requirement for this type of piece, and the parts of the crowd were sung while the solo parts which were the quoted parts from either Christ or the authors were performed in a plainchant.

Lagrime d'amante al sepolcro dell'amata's well known A cappella composition was written in what year?

A:
1610
