(The claim states that) Headphones should be modified for a safe volume level to protect hearing. (Some may disagree because) People would like to hear large amounts of volume, that may damage their ears. They may be destined for free-will, and choose to live their life the way they want. So what if manufacturers choose this way of making headphones, they may see some sales drop as many people don't actually care how loud things are.
        
                    
             
        
        
        
The right answer is the last one: The natural imagery is developed throughout to indicate that nature continues long after humans do. The theme of this poem by the renowned American poet Henry Wadsworth Longfellow (1807-1882) is about the unavoidable passage of time for humans and the repetitive essence and continuity of nature, which, unlike the former (who, as the traveler in the poem, one day stop going back to the shore) is endlessly rising, falling, and returning, like the tide. The elements from nature that are mentioned in the poem - the tide, the sea, the waves - are beautifully personified by Longfellow, making the comparison between the temporality of human life and the permanency of nature even more poignant.
