Final answer:
Obama's statement, 'Tonight is a particular honor for me...,' reflects the rhetorical technique of anaphora.
Step-by-step explanation:
When Obama stated, 'Tonight is a particular honor for me....,' he was using the rhetorical technique of anaphora. Anaphora is a repeated grammatical structure for rhetorical effect, in which the same word or phrase is repeated at the beginning of successive clauses or sentences. In this case, Obama repeated the word 'Tonight' to emphasize the significance and personal meaning of the event for him.
