The answer is: Do not make my love look older.
In Shakespeare's "Sonnet 19," he addresses time and begs it not to grow lines in his love's face. He allows time to execute detructive acts, but he refuses to let it perform the most atrocious act - to make his love look older. He claims that youthfulness must remain unaffected by the progress of time.
Rosaline exemplifies false love because she is only briefly mentioned and never shown, and while Romeo made claims that he loved her, she's forgotten almost immediately after Juliet makes an appearance.
Juliet is an example of true love, because Romeo devoted his heart and ultimately his life to her. He even planned to denounce his last name if it meant they could be together
The example that best describes it is the 1st one; since "dramatic irony" occurs when the audience (<em>readers</em>) understands what's going to happen, and knows about certain characters' actions, or event, and the characters are unaware of it; hence the characters actions go on a different way.
The tactic is used to make the audience more involved; thus it often creates this feeling of being powerless in the readers' mind, to do anything about it.
So the best statement is: "<em>The reader knows that the human neighbors plan to destroy Animal Farm</em>"
