This code defines a simple `KnowledgeBase` class for storing facts and a `ReasoningEngine` to answer questions based on those facts. The example usage demonstrates adding some basic knowledge about the sky and clouds, and then querying the system with a question related to why the sky can appear green at sunrise.
