Final answer:
The passage aims to explain the origins of The Star-Spangled Banner, which was written by Francis Scott Key after the British bombarded Fort McHenry in 1814 during the War of 1812.
Step-by-step explanation:
The passage in question most likely aims to C) tell about the origins of The Star-Spangled Banner. This is supported by the context provided, which mentions that Francis Scott Key wrote the poem 'In Defense of Fort McHenry' after witnessing the British bombardment of Baltimore's Fort McHenry in 1814. Key's poem, which expresses his awe at seeing the American flag still flying after a night of intense battle, was later set to music and became the United States national anthem, known as 'The Star-Spangled Banner'.
This event occurred during the larger context of the War of 1812, which had causes and consequences significant to the development of American national identity and the consolidation of its independence from Britain.
