I want to know the answer to the following question:
Which group did David Attenborough join while on sabbatical?
All the background I'm provided with is that "This unit is now famed throughout the world for producing high quality programmes with Attenborough such as Life on Earth, The Private Life of Plants, The Blue Planet, The Life of Mammals, Planet Earth and Frozen Planet.". Is that enough to answer the question?
Answer: no
