premise: The Icelandic national under-18 basketball team is the representative for Iceland in international Under-18 age basketball competitions, and it is organized and run by the Icelandic Basketball Federation. The team represents Iceland at the FIBA Europe Under-18 Championship. It is coached by Friðrik Ingi Rúnarsson.
hypothesis: Friðrik Ingi Rúnarsson is a player on the basketball team.
reason: He's the coach of the team so he can't be a player. It's difficult because this isn't mentioned explicitly and requires some complex understanding of the subject.
