I want to know the answer to the following question:
How many commercial airports did the British Airports Authority originally operate?
All the background I'm provided with is that "For example, in the United Kingdom the state-owned British Airports Authority originally operated eight of the nation's major commercial airports - it was subsequently privatized in the late 1980s, and following its takeover by the Spanish Ferrovial consortium in 2006, has been further divested and downsized to operating just five.". Is that enough to answer the question?
Answer: yes
