Answer
Brief Explanations:
A run - on sentence combines two or more independent clauses without proper punctuation or conjunctions. The given sentence has a single independent clause "the Potomac Park Levee System was installed to protect the National Mall and surrounding areas in Washington, D.C., from flooding" with an introductory phrase "First completed in 1939". It is grammatically correct and not a run - on.
Answer:
no
