Which of the following are incorrectly capitalized? doctor Nelson Appalachian mountains ethiopian cuisine uncle Pauly algebra I T. S. Eliot society

"Appalachian mountains" is incorrect since "Mountains" should be capitalized as well because it's a proper title. And "Ethiopian" should be capitalized as well since it is a location. "Uncle Pauly" and "TS Eliot Society" should be capitalized since they are proper names.
