Here are the matches for each example with the correct rhetorical technique:
- "give me liberty, or give me death" - allusion
- 'what kind of peace do I mean? what kind of peace do I seek? Not a pax America enforced on the world by weapons of war" - anaphora
- cookies are my Achilles' heel. - allusion
- How many of us could run a marathon - hypophora (the actual term used applies more closely to the rhetorical question format, where the speaker poses a question but does not provide an immediate answer).
Please adjust as necessary if you're focusing on specific instances of rhetorical techniques. For clarity, "couples" can also apply to different terms depending on interpretation; the response to the marathon question can be interpreted as a rhetorical question as well.
