Read the passage below carefully and choose the correct option A, B, C, or D.

     The giraffe is the tallest living animal. It can reach a height of more than 5.5 meters. Giraffes live in eastern Africa. The scientific name of the giraffe is Giraffa Camelopardalis.

     Giraffes have a short body, but their legs and neck are very long. The coat is light brown with reddish brown spots. Many giraffes have two short horns between the ears. Giraffes have large nostrils and a good sense of smell. Giraffes have long tongues of between 45 and 50 centimeters.

     Giraffes are plant eaters. They can reach leaves at the top of trees. But they do not eat grass. It is very hard for them to reach the ground because the neck is stiff. To drink, a giraffe must spread its legs far apart to reach down.

     Giraffes live in herds of up to twenty animals. They use their good eyesight to watch for danger. Lions, cheetahs, and crocodiles are the giraffe's enemies. Giraffes will try to gallop away from danger, but they can fight if necessary. They can run about 50 kilometers an hour.

     A female giraffe gives birth to one calf at a time. The newborn can usually follow its mother around within hours. Giraffes live about 20 to 25 years.

     Giraffes are still common in eastern Africa. They are protected there inside national parks. In Other places, however, hunting has reduced the number of giraffes.
