Read the text and for questions 1-5, choose the correct answer (A, B or C).

Komodo National Park in Indonesia is extremely beautiful. Its protected land and sea area total over 1,800 km2.

This beautiful park is 1/3 land and 2/3 sea with numerous volcanic islands. Visitors can also enjoy its sandy beaches, rolling hills and majestic mountains. The sea is perfect for snorkelling as people enjoy its clear blue water and coral reefs.

The park is home to many amazing animals and plants. It is actually named after a famous lizard: the Komodo dragon. Don't get too close, this 3-metre lizard is dangerous. Many people join tour groups where experienced guides keep them safe while showing them everything the islands have to offer from deer to water buffalo. Some tourists take boat tours to see the sea turtles, whales, and dolphins.

The plant life on the park is also worth seeing. Fruit trees offer coconuts and mangoes, while colourful flowers like orchids offer a great picture opportunity.
