I want to know the answer to the following question:
Where did the torch relay begin in London for the 2008 Olympics?
All the background I'm provided with is that "The torch relay leg held in London, the host city of the 2012 Summer Olympics, on April 6 began at Wembley Stadium, passed through the City of London, and eventually ended at O2 Arena in the eastern part of the city.". Is that enough to answer the question?
Answer: yes
