I want to know the answer to the following question:
What is one of the two major highlands that stretch from the gulf of mexico to the Arctic ocean?
All the background I'm provided with is that "The Laurentian Highlands, the Interior Plains and the Interior Highlands lie between the two coasts, stretching from the Gulf of Mexico northward, far beyond the national boundary, to the Arctic Ocean.". Is that enough to answer the question?
Answer: yes
