Question: Many of the instruments used to perform medieval music still exist, but in different forms. Medieval instruments included the wood flute (which in the 21st century is made of metal), the recorder and plucked string instruments like the lute. As well, early versions of the organ, fiddle (or vielle), and trombone (called the sackbut) existed. Medieval instruments in Europe had most commonly been used singly, often self accompanied with a drone note, or occasionally in parts. From at least as early as the 13th century through the 15th century there was a division of instruments into haut (loud, shrill, outdoor instruments) and bas (quieter, more intimate instruments).
Is there an answer to this question: What was an early version of the trombone called? 

Answer: sackbut


Question: Spain is a unitary state with a high level of decentralisation, often regarded as a federal system in all but name or a "federation without federalism". The country has been quoted as being "an extraordinarily decentralized country", with the central government accounting for just 18% of public spending, 38% for the regional governments, 13% for the local councils, and the remaining 31% for the social security system. The current Spanish constitution has been implemented in such a way that, in many respects, Spain can be compared to countries which are undeniably federal.
Is there an answer to this question: What type of government doesn't Spain have?

Answer: unanswerable


Question: The humanists' close study of Latin literary texts soon enabled them to discern historical differences in the writing styles of different periods. By analogy with what they saw as decline of Latin, they applied the principle of ad fontes, or back to the sources, across broad areas of learning, seeking out manuscripts of Patristic literature as well as pagan authors. In 1439, while employed in Naples at the court of Alfonso V of Aragon (at the time engaged in a dispute with the Papal States) the humanist Lorenzo Valla used stylistic textual analysis, now called philology, to prove that the Donation of Constantine, which purported to confer temporal powers on the Pope of Rome, was an 8th-century forgery. For the next 70 years, however, neither Valla nor any of his contemporaries thought to apply the techniques of philology to other controversial manuscripts in this way. Instead, after the fall of the Byzantine Empire to the Turks in 1453, which brought a flood of Greek Orthodox refugees to Italy, humanist scholars increasingly turned to the study of Neoplatonism and Hermeticism, hoping to bridge the differences between the Greek and Roman Churches, and even between Christianity itself and the non-Christian world. The refugees brought with them Greek manuscripts, not only of Plato and Aristotle, but also of the Christian Gospels, previously unavailable in the Latin West.
Is there an answer to this question: What was included in this quest for knowledge of the belief system?

Answer: Patristic literature
