Information: - The Czechoslovak First League was the premier football league in the Czechoslovakia from 1925 to 1993, with the exception of World War II. Czechoslovakia was occupied by German forces who formed Gauliga Sudetenland and Gauliga Bohmen und Mahren leagues on occupied territories. Until 1934-35 season no teams from Slovakia participated in the league. - The Czechoslovak Cup was a football cup competition held in Czechoslovakia. It was officially created in 1960 and folded in 1993 with the split between Czech Republic and Slovakia. - FC Spartak Trnava is a Slovak professional football club based in Trnava. Historically, it is one of the most successful clubs in country, having won both the Czechoslovak First League and the Czechoslovak Cup five times, and reaching the semi-final of the European Cup once and the quarter-final twice. The club's official anthem is Il Silenzio. - Jasroslav Masrna ( born 5 August 1950 ) is a former Slovak football player , who played for FC Spartak Trnava . - Trnava (also known by other alternative names) is a city in western Slovakia, to the north-east of Bratislava, on the Trnavka river. It is the capital of a "kraj" (Trnava Region) and of an "okres" (Trnava District). It is the seat of a Roman Catholic archbishopric (15411820 and then again since 1977). The city has a historic center. Because of the many churches within its city walls, Trnava has often been called ""parva Roma"", i.e. "Little Rome", or more recently, the "Slovak Rome".

(Question)
Information: - Aerodynamics, from Greek "aer" (air) + (dynamics), is a branch of fluid dynamics concerned with studying the motion of air, particularly when it interacts with a solid object, such as an airplane wing. Aerodynamics is a sub-field of fluid dynamics and gas dynamics, and many aspects of aerodynamics theory are common to these fields. The term "aerodynamics" is often used synonymously with gas dynamics, with the difference being that "gas dynamics" applies to the study of the motion of all gases, not limited to air. Formal aerodynamics study in the modern sense began in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag have been recorded much earlier. Most of the early efforts in aerodynamics worked towards achieving heavier-than-air flight, which was first demonstrated by Wilbur and Orville Wright in 1903. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed the scientific basis for ongoing developments in heavier-than-air flight and a number of other technologies. Recent work in aerodynamics has focused on issues related to compressible flow, turbulence, and boundary layers and has become increasingly computational in nature. - LAPCAT ( Long - Term Advanced Propulsion Concepts and Technologies ) was a 36 - month European FP6 study to examine ways to produce engines for a Mach 4 - 8 hypersonic speed aircraft . The project ended in April 2008 . It was funded by the European Commission research and development fund ( rather than ESA ) , and cost 7 million euros . LAPCAT II , a 10 million euro , four - year , follow on project , started in October 2008 . The study aims to refine some of the results of the first study '' allowing the definition of a detailed development roadmap '' of a Mach five vehicle . - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. - The European Court of Justice (ECJ), officially just the Court of Justice, is the highest court in the European Union in matters of European Union law. As a part of the Court of Justice of the European Union it is tasked with interpreting EU law and ensuring its equal application across all EU member states. The Court was established in 1952 and is based in Luxembourg. It is composed of one judge per member state currently 28 although it normally hears cases in panels of three, five or 15 judges. The court has been led by president Koen Lenaerts since 2015. - The European Commission (EC) is an institution of the European Union, responsible for proposing legislation, implementing decisions, upholding the EU treaties and managing the day-to-day business of the EU. Commissioners swear an oath at the European Court of Justice in Luxembourg, pledging to respect the treaties and to be completely independent in carrying out their duties during their mandate. - In aerodynamics, a hypersonic speed is one that is highly supersonic. Since the 1970s, the term has generally been assumed to refer to speeds of Mach 5 and above. Given the information above, choose from the list below the object entity that exhibits the relation 'instance of' with the subject 'lapcat'. Choices: - aerodynamics - airplane - application - area - branch - capital - century - computer - court - currency - day - economic union - european commission - fluid - home - institution of the european union - law - member - motion - number - part - passport - people - study - term - theory - three - trade - union - wind tunnel
