Why has the zebra never been domesticated and used as a regular means of riding?
Correct Answer
B. It's Skin Rolls From Side To Side
Explanation
The zebra has never been domesticated and used as a regular means of riding because its skin rolls from side to side. This rolling motion makes it difficult for a rider to maintain balance and stability while riding the zebra. Unlike horses, which have a smooth and stable back, the zebra's rolling skin makes it an unsuitable option for riding purposes.

How do salmon find their way back to their home river to spawn every year?
Correct Answer
C. Smell Of The River
