Input: Read this: In early 1757, Frederick II again took the initiative by marching into the Kingdom of Bohemia, hoping to inflict a decisive defeat on Austrian forces. After winning the bloody Battle of Prague on 6 May 1757, in which both forces suffered major casualties, the Prussians forced the Austrians back into the fortifications of Prague. The Prussian army then laid siege to the city. Following the battle at Prague, Frederick took 5,000 troops from the siege at Prague and sent them to reinforce the 19,000-man army under the Duke of Brunswick-Bevern at Kolin in Bohemia. Austrian Marshal Daun arrived too late to participate in the battle of Prague, but picked up 16,000 men who had escaped from the battle. With this army he slowly moved to relieve Prague. The Prussian army was too weak to simultaneously besiege Prague and keep Daun away, and Frederick was forced to attack prepared positions. The resulting Battle of Kolin was a sharp defeat for Frederick, his first military defeat. His losses further forced him to lift the siege and withdraw from Bohemia altogether.
Question: Where did the Austrians retreat in May of 1757?

Output: the fortifications of Prague


Input: Read this: Samskrita Bharati is an organisation working for Sanskrit revival. The "All-India Sanskrit Festival" (since 2002) holds composition contests. The 1991 Indian census reported 49,736 fluent speakers of Sanskrit. Sanskrit learning programmes also feature on the lists of most AIR broadcasting centres. The Mattur village in central Karnataka claims to have native speakers of Sanskrit among its population. Inhabitants of all castes learn Sanskrit starting in childhood and converse in the language. Even the local Muslims converse in Sanskrit. Historically, the village was given by king Krishnadevaraya of the Vijayanagara Empire to Vedic scholars and their families, while people in his kingdom spoke Kannada and Telugu. Another effort concentrates on preserving and passing along the oral tradition of the Vedas, www.shrivedabharathi.in is one such organisation based out of Hyderabad that has been digitising the Vedas by recording recitations of Vedic Pandits.
Question: How many fluent Sanskrit speakers were reported in 2002?

Output: unanswerable


Input: Read this: The simplest model capacitor consists of two thin parallel conductive plates separated by a dielectric with permittivity ε . This model may also be used to make qualitative predictions for other device geometries. The plates are considered to extend uniformly over an area A and a charge density ±ρ = ±Q/A exists on their surface. Assuming that the length and width of the plates are much greater than their separation d, the electric field near the centre of the device will be uniform with the magnitude E = ρ/ε. The voltage is defined as the line integral of the electric field between the plates
Question: What does the line integral of the electric field between the plates of a capacitor represent?

Output: The voltage


Input: Read this: In France, simultaneously, the towering figure of the Gothic Revival was Eugène Viollet-le-Duc, who outdid historical Gothic constructions to create a Gothic as it ought to have been, notably at the fortified city of Carcassonne in the south of France and in some richly fortified keeps for industrial magnates. Viollet-le-Duc compiled and coordinated an Encyclopédie médiévale that was a rich repertory his contemporaries mined for architectural details. He effected vigorous restoration of crumbling detail of French cathedrals, including the Abbey of Saint-Denis and famously at Notre Dame de Paris, where many of whose most "Gothic" gargoyles are Viollet-le-Duc's. He taught a generation of reform-Gothic designers and showed how to apply Gothic style to modern structural materials, especially cast iron.
Question: What famous French cathedral was ruined by Viollet-le-Duc?

Output:
