        return "verified" in fact.statement.lower()

    for fact in facts:
        if check_fact(fact):
            fact.verified = True


# Example usage:
facts = [
    Fact("The sky is blue and verified by a scientist."),
    Fact("The grass is green"),
    Fact("Water freezes at 0 degrees Celsius, which is verified by multiple sources.")

create_fact_checker(facts)

for fact in facts:
    print(f"Statement: {fact.statement} | Verified: {fact.verified}")
```

This code defines a `Fact` class and a function `create_fact_checker` that updates the verification status of given facts based on a simple rule. The example usage demonstrates how to use this capability.
