The other three tests of the worthiness of an argument are consistency, testability, and fruitfulness. The argument in question is consistent since there are no contradictions between the premises and the conclusion. It is also testable, as we can verify the relationships between the siblings using additional information or by asking them directly. Lastly, the argument is fruitful, as it tells us something new about the relationship between Linda and Susan. Therefore, if the premises are true, the argument is valid and worthy of acceptance.
