Question: Information:  - Mathematics (from Greek  "máthma", knowledge, study, learning) is the study of topics such as quantity (numbers), structure, space, and change. There is a range of views among mathematicians and philosophers as to the exact scope and definition of mathematics.  - In mathematics graph theory is the study of "graphs", which are mathematical structures used to model pairwise relations between objects. A graph in this context is made up of "vertices", "nodes", or "points" which are connected by "edges", "arcs", or "lines". A graph may be "undirected", meaning that there is no distinction between the two vertices associated with each edge, or its edges may be "directed" from one vertex to another; see Graph (discrete mathematics) for more detailed definitions and for other variations in the types of graph that are commonly considered. Graphs are one of the prime objects of study in discrete mathematics.  - The Lamsade is a French laboratory located in the Paris Dauphine University, it was created by Bernard Roy in 1976. Lamsade stands for "Laboratoire d'Analyse et de Modélisation des Systèmes pour l'Aide à la Décision". About 70 employees work for this laboratory and six masters (of which two are research-oriented) are associated with the Lamsade. Two main research topics are the computer science and operations research.  - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries.  - ELECTRE is a family of multi-criteria decision analysis methods that originated in Europe in the mid-1960s. The acronym ELECTRE stands for: ELimination Et Choix Traduisant la REalité (ELimination and Choice Expressing REality).  - Bernard Roy ( born in 1934 ) is an emeritus professor at the Université Paris - Dauphine . In 1974 he founded the `` Laboratoire d'Analyse et de Modélisation des Systèmes pour l'Aide à la Décision '' ( Lamsade ) . He has worked on graph theory and on multi-criteria decision analysis ( MCDA ) , having created the ELECTRE family of methods . The name ELECTRE stands for `` ELimination Et Choix Traduisant la REalité '' .    After reading the paragraphs above, we are interested in knowing the entity with which 'bernard roy' exhibits the relationship of 'languages spoken or written'. Find the answer from the choices below.  Choices: - french  - greek  - turkish
