eusong1-7, Exercise 1: Neighbours voting for neighbours

Model answer (any two reasons):

1. Shared taste. Neighbouring countries often have similar music, languages and traditions, so they may genuinely like the same songs.
2. Diaspora. People living in one country may vote for the entry of the country they came from, which looks like a bloc but is a vote by individuals.
3. Shared history and media. Countries that see each other's television know each other's performers.
4. A pattern is not a deal. A statistical pattern shows that results follow geography, not that anyone traded votes.

Conclusion: regional voting exists, and its causes are mixed.
