Odd-one-out (animal classification): Identify the item that does not fit the common biological category. Items to compare by family/diet (hoofed herbivores vs. carnivores/scavengers): Giraffe, Hyena, Deer, Rhinoceros Choose the single word that is different from the rest.

Given data

• Giraffe, Deer, Rhinoceros: herbivorous hoofed mammals (ungulates).
• Hyena: carnivorous/scavenging mammal (family Hyaenidae), not an ungulate.

Concept/Approach Classify by biological family/diet. Three are herbivorous ungulates; one is a carnivore.

Decision Thus, the odd-one-out is Hyena.
