I want to know the answer to the following question:
What Greek volleyball club is the most successful in the country?
All the background I'm provided with is that "Olympiacos is the most successful volleyball club in the country having won the most domestic titles and being the only Greek club to have won European titles; they have won two CEV Cups, they have been CEV Champions League runners-up twice and they have played in as many as 12 Final Fours in the European competitions, making them one of the most traditional volleyball clubs in Europe.". Is that enough to answer the question?
Answer: yes
