This code defines a `KnowledgeBase` class for storing facts and a `ReasoningEngine` class that uses this knowledge base to answer questions by querying for relevant facts. The example usage demonstrates adding some basic facts about Paris and then reasoning about the Eiffel Tower, which shares its city with the given facts.
