I want to know the answer to the following question:
What percent of the Aboriginal population of North America was killed in the first hundred years after first contact by smallpox and measles?
All the background I'm provided with is that "Contact with European diseases such as smallpox and measles killed between 50 and 67 per cent of the Aboriginal population of North America in the first hundred years after the arrival of Europeans.". Is that enough to answer the question?
Answer: yes
