You will be given a definition of a task first, then some input of the task.
In this task, you are given a set of context paragraphs, some supporting facts and an answer of a question. Your task is to generate question for given answer based on set of context paragraphs, supporting facts and an answer.

Context_1 : Leica Camera AG is a German company that manufactures optics and high end cameras. The company was founded by Ernst Leitz in 1924. The name Leica is derived from the first three letters of his surname (Leitz) and the first two of the word camera: lei-ca. Context_2 : The "benefit financing model" (BFM) is an actuarial forecasting model designed to help analysts project the condition of Unemployment Trust Fund (UTF) a number of years into the future, and quickly assess the financial impact of various economic scenarios and possible law changes. This model was constructed to be highly comprehensive yet flexible enough to adapt to individual state needs. It is considered a useful tool in unemployment insurance benefit financing and trust fund forecasting. Context_3 : 4+1 is a view model designed by Philippe Kruchten for "describing the architecture of software-intensive systems, based on the use of multiple, concurrent views". The views are used to describe the system from the viewpoint of different stakeholders, such as end-users, developers and project managers. The four views of the model are logical, development, process and physical view. In addition selected use cases or scenarios are used to illustrate the architecture serving as the 'plus one' view. Hence the model contains 4+1 views: Context_4 : The Contax G1 and Contax G2 are interchangeable-lens cameras sold by Kyocera under the Contax brand in competition with the Leica M7, Cosina Voigtlander Bessa-R, and Konica Hexar RF. The G1 was introduced in 1994 with the G2 joining it in 1996. In 2005, Kyocera announced it would cease all activity related to the manufacture of Contax cameras at the end of the year, effectively spelling the end of the G system. Context_5 : This is a list of Leica cameras. Leica Camera AG is a German optics company which produces Leica cameras. The predecessor of the company, formerly known as Ernst Leitz GmbH, is now three companies: Leica Camera AG, Leica Geosystems AG, and Leica Microsystems AG, producing cameras, geosurvey equipment, and microscopes, respectively. The Leica cameras are grouped by camera model and year of release. Context_6 : The Leica M mount is a camera lens mount introduced in 1954 with the Leica M3, and a range of lenses. It has been used on all the Leica M series up to the current film Leica M7 and digital Leica M. Context_7 : In asset pricing and portfolio management the FamaFrench three-factor model is a model designed by Eugene Fama and Kenneth French to describe stock returns. Fama and French were professors at the University of Chicago Booth School of Business, where Fama still resides. The three factors are (1) market risk, (2) the outperformance of small versus big companies, and (3) the outperformance of high book/market versus small book/market companies. However, the size and book/market ratio themselves are not in the model. For this reason, there is academic debate about the meaning of the last two factors. Context_8 : The Leica M7 is a 35 mm rangefinder camera introduced by Leica AG in 2002 as a direct successor to the M6. The electronic Leica M7 is a departure from previous mechanical designs for the M series. Context_9 : The Modular Ocean Model (MOM) is a three-dimensional ocean circulation model designed primarily for studying the ocean climate system. The model is developed and supported primarily by researchers at the National Oceanic and Atmospheric Administration's Geophysical Fluid Dynamics Laboratory (NOAA/GFDL) in Princeton, USA. Context_10 : The healthcare error proliferation model is an adaptation of James Reason's Swiss Cheese Model designed to illustrate the complexity inherent in the contemporary healthcare delivery system and the attribution of human error within these systems. The healthcare error proliferation model explains the etiology of error and the sequence of events typically leading to adverse outcomes. This model emphasizes the role organizational and external cultures contribute to error identification, prevention, mitigation, and defense construction. fact_1 : The Leica M7 is a 35 mm rangefinder camera introduced by Leica AG in 2002 as a direct successor to the M6. fact_2 : Leica Camera AG is a German company that manufactures optics and high end cameras. Answer: German
Output:
Leica M7 is a model designed by the company of what nationality?
