Assume that the premise(s) of the following argument are true. Apply the other three tests of the worthiness of an argument in their proper order: "Susan is John's younger sister. Linda is John's elder sister. So, Linda is Susan's elder sister." That argument is an example of ________.

A) a fallacy masquerading as a valid inference
B) a fallacy masquerading as a warranted inference
C) a fallacy of relevance
D) a circular argument
E) an argument that is worthy of acceptance, if the premises were in fact true

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.
