Here are the correct matches for each example with the appropriate rhetorical technique:
- Rhetorical question: "What's in a name?"
- Metaphor: Cookies are my Kryptonite.
- Metaphor (or imagery): The frost is glittering crystals on the trees.
- Anaphora: "It was the best of times, it was the worst of times, it was the age of foolishness...."
(Note: The description for "The frost is glittering crystals on the trees" leans towards metaphor or imagery rather than a separate technique, and the line "It was the best of times, it was the worst of times..." is a classic example of anaphora due to its repetitive structure.)
