What strategy do the children employ when trying to communicate effectively with Mr. Benedict?

The children communicate effectively with Mr. Benedict by using Morse Code, which is a method of encoding textual information in a series of dots and dashes. This strategic choice allows them to convey their message discreetly and without drawing unnecessary attention to themselves or their surroundings. Morse Code can be particularly useful in situations where silence is necessary or where they must avoid detection, showcasing their resourcefulness and creativity in communication.

Using elaborate drawings, simple gestures, or loud voices may not effectively convey complex messages or maintain the level of secrecy required in their context. Morse Code allows for a nuanced exchange that aligns with their need for careful and clever communication as they work together to solve problems and strategize their next moves. This approach reflects the children's adaptability and intelligence in utilizing available methods to achieve their goals while cooperating with Mr. Benedict.
