Input: Read this: General Electric switched to use the ASA scale in 1946. Meters manufactured since February 1946 were equipped with the ASA scale (labeled "Exposure Index") already. For some of the older meters with scales in "Film Speed" or "Film Value" (e.g. models DW-48, DW-49 as well as early DW-58 and GW-68 variants), replaceable hoods with ASA scales were available from the manufacturer. The company continued to publish recommended film values after that date, however, they were now aligned to the ASA scale.
Question: Beginning what year were cameras built with the ASA meter?

Output: 1946


Input: Read this: Within the city there have been two tram networks in operation. A proposal to develop a horse-drawn tram (linking the city's railway termini) was made by American George Francis Train in the 1860s, and implemented in 1872 by the Cork Tramway Company. However, the company ceased trading in 1875 after Cork Corporation refused permission to extend the line, mainly because of objections from cab operators to the type of tracks which – although they were laid to the Irish national railway gauge of 5 ft 3in – protruded from the road surface.[citation needed]
Question: Why did the cab operators not like the tracks?

Output: protruded from the road surface


Input: Read this: Michel Foucault claims that the contemporary concept of police as a paid and funded functionary of the state was developed by German and French legal scholars and practitioners in Public administration and Statistics in the 17th and early 18th centuries, most notably with Nicolas Delamare's Traité de la Police ("Treatise on the Police"), first published in 1705. The German Polizeiwissenschaft (Science of Police) first theorized by Philipp von Hörnigk a 17th-century Austrian Political economist and civil servant and much more famously by Johann Heinrich Gottlob Justi who produced an important theoretical work known as Cameral science on the formulation of police. Foucault cites Magdalene Humpert author of Bibliographie der Kameralwissenschaften (1937) in which the author makes note of a substantial bibliography was produced of over 4000 pieces of the practice of Polizeiwissenschaft however, this maybe a mistranslation of Foucault's own work the actual source of Magdalene Humpert states over 14,000 items were produced from the 16th century dates ranging from 1520-1850.
Question: What was von Hornigk's career?

Output: Political economist and civil servant


Input: Read this: The Germanic languages are traditionally divided into three groups: West, East and North Germanic. They remained mutually intelligible throughout the Migration Period. Dutch is together with English and German part of the West Germanic group, that is characterized by a number of phonological and morphological innovations not found in North and East Germanic. The West Germanic varieties of the time are generally split into three dialect groups: Ingvaeonic (North Sea Germanic), Istvaeonic (Weser-Rhine Germanic) and Irminonic (Elbe Germanic). It appears that the Frankish tribes fit primarily into the Istvaeonic dialect group with certain Ingvaeonic influences towards the northwest, still seen in modern Dutch.
Question: In what historical period did the different types of Germanic languages stop being collectively understood?

Output:
the Migration Period
