I want to know the answer to the following question:
What country do the Appalachian mountains extend into?
All the background I'm provided with is that "The range is mostly located in the United States but extends into southeastern Canada, forming a zone from 100 to 300 mi (160 to 480 km) wide, running from the island of Newfoundland 1,500 mi (2,400 km) southwestward to Central Alabama in the United States.[discuss]". Is that enough to answer the question?
Answer: yes
