Final answer:
The paraphrase that best encapsulates Shakespeare's lines from 'Sonnet 65' is about the fragility of life against the relentless force of time.
Step-by-step explanation:
The best paraphrase of the lines from Shakespeare's "Sonnet 65" is 'How can something as fragile as life resist the destructive force of time?' This paraphrase captures the essence of the original text, which questions the ability of the delicate and transient aspects of nature (represented by 'summer's honey breath') to endure the relentless passage of time (described as 'wreckful siege of battering days'). The sonnet reflects on the theme of the impermanence of beauty and the inevitable decay brought by time.
