I want to know the answer to the following question:
How many elders did John Batman claim to have negotiated with?
All the background I'm provided with is that "In May and June 1835, the area which is now central and northern Melbourne was explored by John Batman, a leading member of the Port Phillip Association in Van Diemen's Land (now known as Tasmania), who claimed to have negotiated a purchase of 600,000 acres (2,400 km2) with eight Wurundjeri elders.". Is that enough to answer the question?
Answer: yes
