Final answer:
Helmholz finds amusement in the concept of romantic love, tragic endings, and emotional intensity in Romeo and Juliet.
Step-by-step explanation:
Helmholz bursts into laughter when John reads to him from Romeo and Juliet because of three things that amuse him. These include:
- The concept of romantic love, which is a key theme in the play. Helmholz may find amusement in the idealistic and passionate portrayal of love between Romeo and Juliet.
- The tragic endings in the play, where the young lovers meet a fate of death. This could be seen as darkly ironic or comical to Helmholz.
- The emotional intensity throughout the play, which includes moments of heightened drama and extreme emotions. Helmholz may find amusement in the melodramatic aspects of the story.
