It is effective in that the rhetorical devices emphasise the message the author is trying to send:
- hypophora this is the exclamation and tone that the message sends forth
- parallelism is the comparison that the author makes between liberty or death, the author is declaring that life and liberty are one or the other
- repetition is the authors use of Give me which suggest that the author is in some way speaking to someone asking them to make a decision, likely someone with power
