I want to know the answer to the following question:
How much did the second world tour make in dollars?
All the background I'm provided with is that "Achieving the accomplishment of becoming her longest-running Hot 100 single in her career, "Halo"'s success in the US helped Beyoncé attain more top-ten singles on the list than any other woman during the 2000s.". Is that enough to answer the question?
