I think undergraduates. I´m going to second guess myself and say alumni. Wait, I talked it over with myself and I think I wrote the right answer first. Lol, hope this helps.
Correlative conjunctions are conjunctions that are used to connect equal or balanced clauses. These include neither/nor, either/or, both/and, not..only, but...also and whether/or. From the given conjunctions above, the choice that is not a correlative conjunction is option c. both..yet. The pair of both should not be "yet" but "and".
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.
Hope this helps!
