Scout believes the world is ending because it was snowing outside. She had never seen snow before.
The correct answer is 'Yellowstone National Park, the West's oldest national park, is the site of Old Faithful'. 'Yellowstone National Park', 'West', and 'Old Faithful' are all proper nouns, so they need to be capitalized. 'National park' does not need to be capitalized, because 'park' is a common noun, and 'national' is just an adjective describing it.
