Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct option to each of the questions that follow.

     Kangaroos are marsupials, which means that their young are born at a very early stage of development and continue to develop outside the mother's body, usually in a pouch on the mother's belly. Kangaroos have large, powerful hind legs and a long, strong tail. They use their tails for balance while jumping. Kangaroos can travel at speeds up to 30 miles per hour and can leap some 30 feet in a single bound. Kangaroos use their small front legs to grasp objects.

     There are four different kangaroo species: the red kangaroo, eastern grey kangaroo, western grey kangaroo, and antilopine kangaroo. The red kangaroo is the largest marsupial, and males can grow up to six feet tall. Red kangaroos live in groups called mobs. Eastern grey kangaroos also live in mobs and can be found in forests and woodlands along the eastern coast of Australia. Western grey kangaroos live in the southern part of Western Australia and can be found in large numbers in the area around Perth. Antilopine kangaroos are found in northern Australia and New Guinea.

     Kangaroos are herbivores, which means that they eat plants. They mainly eat grass, but they will also eat shrubs and trees if food is scarce. Kangaroos are nocturnal animals, which means that they are most active during the night. During the day, kangaroos rest in the shade or in caves. The average lifespan of a kangaroo is six years.
