I want to know the answer to the following question:
How many UEFA Championship League titles has Barcelona won?
All the background I'm provided with is that "In international club football, Barcelona has won five UEFA Champions League titles, a record four UEFA Cup Winners' Cup, a shared record five UEFA Super Cup, a record three Inter-Cities Fairs Cup and a record three FIFA Club World Cup trophies.". Is that enough to answer the question?
Answer: yes
