I want to know the answer to the following question:
What is the span of population density per million square kilometers of researchers in Antarctica?
All the background I'm provided with is that "The number of people conducting and supporting scientific research and other work on the continent and its nearby islands varies from about 1,000 in winter to about 5,000 in the summer, giving it a population density between 70 and 350 inhabitants per million square kilometres (180 and 900 per million square miles) at these times.". Is that enough to answer the question?
Answer: yes
