Which sluggish tailless Australian marsupial has gray fur and ears?

• A. Wombat
• B. Kangaroo
• C. Tasmanian devil
• D. Koala

Answer: (D)

Think about a tree-dwelling marsupial known for moving slowly and having distinctive large ears with gray fur. That description points to the koala. Koalas spend most of their time in eucalyptus trees and conserve energy by moving at a slow pace on their leaf diet. Their fur is the soft gray color, and their ears are large and fluffy, which makes them stand out. They are tailless, which helps separate them from other marsupials like kangaroos that have tails and use them for balance. Wombats are sturdier burrowers with shorter tails, and Tasmanian devils are typically smaller and darker, so they don’t fit the given description as well.
