I want to know the answer to the following question:
About how many people visited the 2008 European Beer Festival?
All the background I'm provided with is that "This newly established Danish interest in British cask beer and the British pub tradition is reflected by the fact that some 56 British cask beers were available at the 2008 European Beer Festival in Copenhagen, which was attended by more than 20,000 people.". Is that enough to answer the question?
Answer: yes
