This code defines a `Fact` dataclass to hold statements and their statuses (truth values). It also includes a function `create_fact_checker()` which returns another function capable of checking the validity of given statements against a predefined set of facts. An example usage is provided at the bottom of the script, showing how to create and use this fact checker.
