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.
When imagining a rhino, you may picture a tank-like rhino with a three-foot horn on the African savannah. But there are five different species of rhinos three that live in Asia and two that live in Africa. Javan rhinos inhabit Asian rainforests on the island of Java. The island lies in the ocean south of Vietnam and north of Australia. Javan rhinos have only one, small horn about 10 inches long, setting them apart from their African relatives.
Poaching has been a past and present threat for Javan rhinos. Farmers have killed rhinos invading their fields or threatening crops. Poachers hunt rhinos for their horns, which are used in traditional Asian medicine. As a result, Javan rhinos are the most endangered large mammal, with only 67 known to exist. All Javan rhinos live in one national park called Ujung Kulon National Park.
But even at Ujung Kulon, Javan rhinos face challenges. An eruption of the nearby Anak Krakatau volcano could destroy the world's population of Javan rhinos. Despite being protected, human activity has invaded the park and damaged the rhino habitat. And an invasive palm tree has choked out much of the rhino's native food supply.
Organisations, like the Rhino Foundation of Indonesia, work with park staff to improve protections for the Javan rhino found in Ujung Kulon. In addition, the World Wildlife Fund developed plans to introduce a second population of Javan rhinos in another protected park to reduce the likelihood of extinction.
