Final answer:
The phrase provided is alliteration, not antithesis, because it does not contrast ideas but instead uses repetitive sounds for literary effect.
Step-by-step explanation:
The phrase “The deafening din of dynamite” is not an example of antithesis, but rather an example of alliteration due to the repetition of the initial 'd' sound. Antithesis involves a contrast of ideas or words in a parallel construction.
An example of antithesis would be “To err is human; to forgive, divine” by Alexander Pope, where human fallibility is contrasted with divine perfection.
