"You really must try out to be selected in the basketball team because my uncle who teaches philosophy says that you have real potential." Identify the logical fallacy committed in the above argument.

The argument appeals to an inappropriate authority.

A philosophy-teaching uncle is cited to judge basketball potential.

Expertise in philosophy gives no competence in athletic selection.

The authority lies outside the field of the claim being made.

Citing such an unfit expert is the appeal to inappropriate authority.
