I want to know the answer to the following question:
In which facility is the London Symphony Orchestra based?
All the background I'm provided with is that "The city is also home to many orchestras and concert halls, such as the Barbican Arts Centre (principal base of the London Symphony Orchestra and the London Symphony Chorus), Cadogan Hall (Royal Philharmonic Orchestra) and the Royal Albert Hall (The Proms).". Is that enough to answer the question?
Answer: yes
