This code snippet defines a basic reasoning engine in Python that adds and queries knowledge about different topics. It includes an `add_knowledge` method to populate the knowledge base with facts, and an `infer` method to make simple inferences based on those facts. The `example_usage` function demonstrates how to use this class.
