Final answer:
The boys' behavior can be attributed to their exposure to Superman on TV and their limited understanding of reality at their young age. Children are curious and may imitate actions they see, even if they are dangerous. Parental supervision and clear boundaries are vital to prevent such incidents.
Step-by-step explanation:
The boys' behavior can be explained by their exposure to the concept of flying through watching Superman on television. At the age of 4, children are still in the early stages of development and have difficulty distinguishing between reality and fantasy. They may imitate or attempt to reenact actions they see, even if they are dangerous or impossible.
Children at this age are also curious and eager to explore their environment. Seeing Superman fly may have sparked their curiosity and desire to try it themselves, leading them to climb onto the roof and attempt to experiment with flying.
It is important for parents to supervise and guide children's behavior, especially when it comes to dangerous activities. Engaging in open communication and setting clear boundaries can help prevent such situations.
