Task 1.1 Read the text and answer the questions.
Komodo National Park in Indonesia is extremely beautiful. Its protected land and sea area total over 1,800 km2.

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.
