Question: Upon the invitation of Duke Konrad I of Masovia, the Teutonic Knights took possession of Prussia in the 13th century and created a monastic state to administer the conquered Old Prussians. Local Old-Prussian (north) and Polish (south) toponyms were gradually Germanised. The Knights' expansionist policies, including occupation of Polish Pomerania with Gdansk/Danzig and western Lithuania, brought them into conflict with the Kingdom of Poland and embroiled them in several wars, culminating in the Polish-Lithuanian-Teutonic War, whereby the united armies of Poland and Lithuania, defeated the Teutonic Order at the Battle of Grunwald (Tannenberg) in 1410. Its defeat was formalised in the Second Treaty of Thorn in 1466 ending the Thirteen Years' War, and leaving the former Polish region Pomerania/Pomerelia under Polish control. Together with Warmia it formed the province of Royal Prussia. Eastern Prussia remained under the Knights, but as a fief of Poland. 1466 and 1525 arrangements by kings of Poland were not verified by the Holy Roman Empire as well as the previous gains of the Teutonic Knights were not verified.

Question: The offices of elder and ministerial servant were restored to Witness congregations in 1972, with appointments made from headquarters (and later, also by branch committees). It was announced that, starting in September 2014, appointments would be made by traveling overseers. In a major organizational overhaul in 1976, the power of the Watch Tower Society president was diminished, with authority for doctrinal and organizational decisions passed to the Governing Body. Since Knorr's death in 1977, the position of president has been occupied by Frederick Franz (19771992) and Milton Henschel (19922000), both members of the Governing Body, and since 2000 by Don A. Adams, not a member of the Governing Body. In 1995, Jehovah's Witnesses abandoned the idea that Armageddon must occur during the lives of the generation that was alive in 1914 and in 2013 changed their teaching on the "generation".
Is there an answer to this question: Who was one of the members of the Governing Body in 1995?

Answer: unanswerable

Question: Two contrasting viewpoints on time divide many prominent philosophers. One view is that time is part of the fundamental structure of the universea dimension independent of events, in which events occur in sequence. Sir Isaac Newton subscribed to this realist view, and hence it is sometimes referred to as Newtonian time. The opposing view is that time does not refer to any kind of "container" that events and objects "move through", nor to any entity that "flows", but that it is instead part of a fundamental intellectual structure (together with space and number) within which humans sequence and compare events. This second view, in the tradition of Gottfried Leibniz and Immanuel Kant, holds that time is neither an event nor a thing, and thus is not itself measurable nor can it be travelled.
Is there an answer to this question: What kind of time did Gottfried Leibniz believe in, as a supporter of Sir Isaac Newton?

Answer: unanswerable

Question: Valencia is a bilingual city: Valencian and Spanish are the two official languages. Spanish is official in all of Spain, whereas Valencian is official in the Valencian Country, as well as in Catalonia and the Balearic Islands, where it receives the name of Catalan. Despite the differentiated denomination, the distinct dialectal traits and political tension between Catalonia and the Valencian Country, Catalan and Valencian are mutually intelligible and are considered two varieties of the same language.
Valencian has been historically repressed in favour of Spanish. The effects have been more noticeable in the city proper, whereas the language has remained active in the rural and metropolitan areas. After the Castille-Aragon unification, a Spanish-speaking elite established itself in the city. In more recent history, the establishment of Franco's military and administrative apparatus in Valencia further excluded Valencian from public life. Valencian recovered its official status, prestige and use in education after the transition to democracy in 1978. However, due to industrialisation in recent decades, Valencia has attracted immigration from other regions in Spain, and hence there is also a demographic factor for its declining social use. Due to a combination of these reasons, Valencia has become the bastion of anti-Catalan blaverism, which celebrates Valencian as merely folkloric, but rejects the existing standard which was adapted from Catalan orthography.
Spanish is currently the predominant language in the city proper but, thanks to the education system, most Valencians have basic knowledge of both Spanish and Valencian, and either can be used in the city. Valencia is therefore the second biggest Catalan-speaking city after Barcelona. Institutional buildings and streets are named in Valencian. The city is also home to many pro-Valencian political and civil organisations. Furthermore, education entirely in Valencian is offered in more than 70 state-owned schools in the city, as well as by the University of Valencia across all disciplines.
Is there an answer to this question: When did Valencian regain its offical status?

Answer:
1978
