Final answer:
The word 'worldwide' from John F. Kennedy's "Civil Rights Address" emphasizes the universal impact of civil rights by indicating the struggle is global.
Step-by-step explanation:
The diction in John F. Kennedy's "Civil Rights Address" that emphasizes that everyone is impacted by civil rights is the word worldwide. This term conveys that the struggle for civil rights is not confined to any single nation or region but is a global issue affecting all who aspire to be free. The use of worldwide in this context highlights the universality of civil rights and the fact that the protection of these rights is a concern that transcends national boundaries. Other terms like committed, promote, and rights also play essential roles in the sentence, but worldwide is the one that most broadly emphasizes the impact on everyone, regardless of their location.
