Multilingualism is typical of the European Union. Yet, as the number of member countries increases, more and more pressure will push for a common language. English is the likely candidate, particularly in view of the fact that it's the most widely studied foreign language. This is true in Europe as well as the rest of the world. Some people already view English as a basic subject alongside of the national language (s), math, and science. Will the European Union solve its linguistic "problems" and choose English as the only language? I think a more likely scenario is that several major languages will be chosen as official ones, which is what what has happened in the UN.
