Problem: Please answer a question about the following article about Cork (city):
Cork was one of the most rail-oriented cities in Ireland, featuring eight stations at various times. The main route, still much the same today, is from Dublin Heuston. Originally terminating on the city's outskirts at Blackpool, the route now reaches the city centre terminus of Kent Station via Glanmire tunnel. Now a through station, the line through Kent connects the towns of Cobh and Midleton east of the city. This also connected to the seaside town of Youghal, until the 1980s.[citation needed]
How many rail stations has cork had over the years?
A: eight
Problem: Please answer a question about the following article about Group (mathematics):
The convergence of these various sources into a uniform theory of groups started with Camille Jordan's Traité des substitutions et des équations algébriques (1870). Walther von Dyck (1882) introduced the idea of specifying a group by means of generators and relations, and was also the first to give an axiomatic definition of an "abstract group", in the terminology of the time. As of the 20th century, groups gained wide recognition by the pioneering work of Ferdinand Georg Frobenius and William Burnside, who worked on representation theory of finite groups, Richard Brauer's modular representation theory and Issai Schur's papers. The theory of Lie groups, and more generally locally compact groups was studied by Hermann Weyl, Élie Cartan and many others. Its algebraic counterpart, the theory of algebraic groups, was first shaped by Claude Chevalley (from the late 1930s) and later by the work of Armand Borel and Jacques Tits.
What theory did Hermann Weyl study in addition to locally compact groups?
A: The theory of Lie groups
Problem: Please answer a question about the following article about History of science:
The scientific revolution is a convenient boundary between ancient thought and classical physics. Nicolaus Copernicus revived the heliocentric model of the solar system described by Aristarchus of Samos. This was followed by the first known model of planetary motion given by Johannes Kepler in the early 17th century, which proposed that the planets follow elliptical orbits, with the Sun at one focus of the ellipse. Galileo ("Father of Modern Physics") also made use of experiments to validate physical theories, a key element of the scientific method.
Johannes Kepler created a model of what?
A:
planetary motion
