Input: Read this: Maintaining continuity with his predecessors, John XXIII continued the gradual reform of the Roman liturgy, and published changes that resulted in the 1962 Roman Missal, the last typical edition containing the Tridentine Mass established in 1570 by Pope Pius V at the request of the Council of Trent and whose continued use Pope Benedict XVI authorized in 2007, under the conditions indicated in his motu proprio Summorum Pontificum. In response to the directives of the Second Vatican Council, later editions of the Roman Missal present the 1970 form of the Roman Rite.
Question: What did Pope John XXIII establish in 1570?

Output: unanswerable


Input: Read this: During a visit in 1885 English journalist George Augustus Henry Sala coined the phrase "Marvellous Melbourne", which stuck long into the twentieth century and is still used today by Melburnians. Growing building activity culminated in a "land boom" which, in 1888, reached a peak of speculative development fuelled by consumer confidence and escalating land value. As a result of the boom, large commercial buildings, coffee palaces, terrace housing and palatial mansions proliferated in the city. The establishment of a hydraulic facility in 1887 allowed for the local manufacture of elevators, resulting in the first construction of high-rise buildings; most notably the APA Building, amongst the world's tallest commercial buildings upon completion in 1889. This period also saw the expansion of a major radial rail-based transport network.
Question: In what year was the APA Building completed?

Output: 1889


Input: Read this: Romanesque architecture in Germany, Poland, the Czech Lands and Austria is characterised by its massive and modular nature. This is expressed in the Gothic architecture of Central Europe in the huge size of the towers and spires, often projected, but not always completed. The west front generally follows the French formula, but the towers are very much taller and, if complete, are surmounted by enormous openwork spires that are a regional feature. Because of the size of the towers, the section of the façade between them may appear narrow and compressed. The eastern end follows the French form. The distinctive character of the interior of German Gothic cathedrals is their breadth and openness. This is the case even when, as at Cologne, they have been modelled upon a French cathedral. German cathedrals, like the French, tend not to have strongly projecting transepts. There are also many hall churches (Hallenkirchen) without clerestory windows.
Question: What is the only design element in German Gothic cathedrals?

Output: unanswerable


Input: Read this: The creation of the Federal Republic of Germany in 1949 was through the unification of the western states (which were previously under American, British, and French administration) created in the aftermath of World War II. Initially, in 1949, the states of the Federal Republic were Baden, Bavaria (in German: Bayern), Bremen, Hamburg, Hesse (Hessen), Lower Saxony (Niedersachsen), North Rhine Westphalia (Nordrhein-Westfalen), Rhineland-Palatinate (Rheinland-Pfalz), Schleswig-Holstein, Württemberg-Baden, and Württemberg-Hohenzollern. West Berlin, while officially not part of the Federal Republic, was largely integrated and considered as a de facto state.
