Input: Read this: Fryderyk Chopin was born in Żelazowa Wola, 46 kilometres (29 miles) west of Warsaw, in what was then the Duchy of Warsaw, a Polish state established by Napoleon. The parish baptismal record gives his birthday as 22 February 1810, and cites his given names in the Latin form Fridericus Franciscus (in Polish, he was Fryderyk Franciszek). However, the composer and his family used the birthdate 1 March,[n 2] which is now generally accepted as the correct date.
Question: What was the latin form of Frédéric's full name?

Output: Fridericus Franciscus


Input: Read this: There were 72.1 million visitors to the city's museums and monuments in 2013. The city's top tourist attraction was the Notre Dame Cathedral, which welcomed 14 million visitors in 2013. The Louvre museum had more than 9.2 million visitors in 2013, making it the most visited museum in the world. The other top cultural attractions in Paris in 2013 were the Basilique du Sacré-Cœur (10.5 million visitors); the Eiffel Tower (6,740,000 visitors); the Centre Pompidou (3,745,000 visitors) and Musée d'Orsay (3,467,000 visitors). In the Paris region, Disneyland Paris, in Marne-la-Vallée, 32 km (20 miles) east of the centre of Paris, was the most visited tourist attraction in France, with 14.9 million visitors in 2013.
Question: How many people visited the Louvre in 2013?

Output: 9.2 million


Input: Read this: After Christianization, the Roman Catholic Church and local rulers led German expansion and settlement in areas inhabited by Slavs and Balts, known as Ostsiedlung. During the wars waged in the Baltic by the Catholic German Teutonic Knights; the lands inhabited by the ethnic group of the Old Prussians (the current reference to the people known then simply as the "Prussians"), were conquered by the Germans. The Old Prussians were an ethnic group related to the Latvian and Lithuanian Baltic peoples. The former German state of Prussia took its name from the Baltic Prussians, although it was led by Germans who had assimilated the Old Prussians; the old Prussian language was extinct by the 17th or early 18th century. The Slavic people of the Teutonic-controlled Baltic were assimilated into German culture and eventually there were many intermarriages of Slavic and German families, including amongst the Prussia's aristocracy known as the Junkers. Prussian military strategist Karl von Clausewitz is a famous German whose surname is of Slavic origin. Massive German settlement led to the assimilation of Baltic (Old Prussians) and Slavic (Wends) populations, who were exhausted by previous warfare.
Question: Who conquered the Catholic German Teutonic Knights?

Output: unanswerable


Input: Read this: As a side effect of the electrochemical processes used by neurons for signaling, brain tissue generates electric fields when it is active. When large numbers of neurons show synchronized activity, the electric fields that they generate can be large enough to detect outside the skull, using electroencephalography (EEG) or magnetoencephalography (MEG). EEG recordings, along with recordings made from electrodes implanted inside the brains of animals such as rats, show that the brain of a living animal is constantly active, even during sleep. Each part of the brain shows a mixture of rhythmic and nonrhythmic activity, which may vary according to behavioral state. In mammals, the cerebral cortex tends to show large slow delta waves during sleep, faster alpha waves when the animal is awake but inattentive, and chaotic-looking irregular activity when the animal is actively engaged in a task. During an epileptic seizure, the brain's inhibitory control mechanisms fail to function and electrical activity rises to pathological levels, producing EEG traces that show large wave and spike patterns not seen in a healthy brain. Relating these population-level patterns to the computational functions of individual neurons is a major focus of current research in neurophysiology.
Question: What type of test is used to tell that a brain is active even during sleep?

Output:
EEG
