question: even:odd:integer
choices.label: A B C D
choices.text: plant:animal:organism teaching assistant:lecturer:professor platoon commander:company commander:battalion commander rational:irrational:axiom
explanation: "even" and "odd" contradict each other, "even" and "odd" belong to "integer". both "plant" and "animal" belong to "organism", while bacteria, fungi, etc. also belong to "organism" "teaching assistant", "lecturer" and "professor" are all titles, "teaching assistant" and "lecturer" are not "professor" "platoon commander", "company commander" and "battalion commander" are all titles, "platoon commander" and "company commander" are not "battalion commander" "rational" and "irrational" contradict each other, but have no obvious logical relationship with "axiom".
