Which is a normal 3-year-old milestone?

• A. Stand on one foot and balance
• B. Run a marathon
• C. Solve algebra
• D. Read a picture book

Answer: (A)

Balancing ability and gross-motor control are being assessed here. A typical 3-year-old can stand on one foot for a brief moment while keeping balance, showing developing unilateral stability that underpins later skills like hopping and running. The other options require levels of endurance, cognitive math, or reading development that aren’t expected for a child this age—running a marathon is an endurance feat for adults, solving algebra is beyond preschool math, and fluent reading isn’t usually present at age three (picture-book interaction may occur, but not full reading). So standing on one foot and balancing is the normal 3-year-old milestone.
