What is the name of the national anthem?

What does this answer mean?

The name of the national anthem is "The Star-Spangled Banner."

The words were written by Francis Scott Key, a lawyer and poet, during the War of 1812. In September 1814, after watching British ships bombard Fort McHenry, which protected the harbor of Baltimore, Maryland, Key saw the large American flag still flying over the fort at dawn. That sight inspired his poem, first called "Defence of Fort McHenry," which was later set to music.

The song was popular for more than a century before it became official. Congress made "The Star-Spangled Banner" the national anthem on March 3, 1931, and President Herbert Hoover signed the law.

The "banner" in the title is the flag, and the stars on it are the "star-spangled" part. That connects this question to the questions about the flag's stars and stripes.

At the interview, say "The Star-Spangled Banner."
