Teacher: Now, understand the problem? Solve this instance: Passage: Spain is a unitary state with a high level of decentralisation, often regarded as a federal system in all but name or a "federation without federalism". The country has been quoted as being "an extraordinarily decentralized country", with the central government accounting for just 18% of public spending, 38% for the regional governments, 13% for the local councils, and the remaining 31% for the social security system. The current Spanish constitution has been implemented in such a way that, in many respects, Spain can be compared to countries which are undeniably federal.
Student:
What type of state isn't Spain?
