insert one dash where needed.\nbeneath the church of santa maria della concezione in rome, italy, lies a burial chamber a six-room crypt filled with the skulls and other bones of about four thousand monks.
Answer
Brief Explanations:
To clarify the relationship between "burial chamber" and "a six - room crypt" (where the latter defines the former), we need to insert an em - dash (the provided dash) between them. So the corrected sentence is: "Beneath the church of Santa Maria della Concezione in Rome, Italy, lies a burial chamber — a six - room crypt filled with the skulls and other bones of about four thousand monks."
Answer:
Insert the dash between "chamber" and "a", so the sentence becomes: "Beneath the church of Santa Maria della Concezione in Rome, Italy, lies a burial chamber — a six - room crypt filled with the skulls and other bones of about four thousand monks."
