Problem: FC Barcelona:

Like Maradona, Ronaldo only stayed a short time before he left for Internazionale. However, new heroes emerged, such as Luis Figo, Patrick Kluivert, Luis Enrique and Rivaldo, and the team won a Copa del Rey and La Liga double in 1998. In 1999, the club celebrated its centenari, winning the Primera Division title, and Rivaldo became the fourth Barcelona player to be awarded European Footballer of the Year. Despite this domestic success, the failure to emulate Real Madrid in the Champions League led to van Gaal and Nunez resigning in 2000.

How long did Ronaldo remain with Barcelona?

Problem: Federations often employ the paradox of being a union of states, while still being states (or having aspects of statehood) in themselves. For example, James Madison (author of the US Constitution) wrote in Federalist Paper No. 39 that the US Constitution "is in strictness neither a national nor a federal constitution; but a composition of both. In its foundation, it is federal, not national; in the sources from which the ordinary powers of the Government are drawn, it is partly federal, and partly national..." This stems from the fact that states in the US maintain all sovereignty that they do not yield to the federation by their own consent. This was reaffirmed by the Tenth Amendment to the United States Constitution, which reserves all powers and rights that are not delegated to the Federal Government as left to the States and to the people.

Those of English and Irish ancestry are present in large numbers in all the urban/suburban areas across the state. Some native white Floridians, especially those who have descended from long-time Florida families, may refer to themselves as "Florida crackers"; others see the term as a derogatory one. Like whites in most of the other Southern states, they descend mainly from English and Scots-Irish settlers, as well as some other British American settlers.
