add a comma or semicolon if needed. otherwise, submit the text without any additional punctuation.\n\nprofessor tyler nordgren promotes the beauty of the night sky in americas national parks lassen volcanic natural park, bryce canyon national park, and acadia national park are some of his favorites for stargazing.
Answer
Explanation:
Step1: Analyze Sentence Structure
The first part of the sentence introduces Professor Nordgren's promotion of the night sky in national parks. The second part lists specific parks as examples. A semicolon is needed to separate two independent clauses (each could stand as a sentence) that are related in content.
Step2: Apply Punctuation
Insert a semicolon between "parks" and "Lassen" to properly separate the two clauses.
Answer:
Professor Tyler Nordgren promotes the beauty of the night sky in America's national parks; Lassen Volcanic Natural Park, Bryce Canyon National Park, and Acadia National Park are some of his favorites for stargazing.
