Passage A
The Giraffe
The giraffe is the tallest modern land animal. It can be over 5. 5 meters tall. Its neck bone may be 1. 9 meters long. Yet the giraffe has only seven bones in its neck, the same number as in the human. Even a small bird has many more bones in its neck than in a tall giraffe. Each bone in a giraffe’s neck is very long, while the bones in a human’s neck are small. That makes the difference. A female giraffe gives birth to one baby at a time. The baby, called a calf, is about 1. 9 meters tall at birth. By the age of eight it is full-grown. The giraffe can live for 30 years; the giraffe is good at running; it can run 30 kilometers per hour. The giraffe likes to live together, usually 7-10 a group. The giraffe eats mostly leaves. Because it has a long neck, it can reach the leaves high up on the trees.
