I want to know the answer to the following question:
What are the two main native Alaskan language families?
All the background I'm provided with is that "Most of Alaska's native languages belong to either the Eskimo–Aleut or Na-Dene language families however some languages are thought to be isolates (e.g. Haida) or have not yet been classified (e.g. Tsimshianic).". Is that enough to answer the question?
Answer: yes
