The following text is for questions 13 to 16. Komodo Dragons Not Under Stress: Head of Komodo National Park     The head of East Nusa Tenggara's (NTT) Komodo National Park, Sudiyono, has denied reports saying that komodo dragons at the park are under stress as a result of tourists.     "The komodo dragons are comfortable, so far. There may be a change in attitude, but they're not stressed. When the animal is stressed out, they become aggressive and until now there hasn't been any aggressive behavior," Sudiyono explained.     His remarks came as a response to reports aying that an increase in the number of visitors at the park caused stress on the lizard species, the largest in the world.     Sudiyono said no special studies were carried out that proved the komodo dragons were stressed, however, he noted that the dragons were more aggressive if they were disturbed while eating.     "The komodo dragons will be more aggressive when they are eating or being disturbed while eating. If they have finished eating but they see something moving, thetr instincts will tell them that [the moving object] is food," he said.     Speaking on recent cases in which visitors were attacked by komodo dragons, Sudiyono said the attacks occurred because the visitors were not with their guide. Visitors must be accompanied by a guide at all times, according to park rules. ·     In regard to the rising number of visitors, Sudiyono said the situation was automatically controlled by the limited number of available guides and the visitors taking part in other activities, such as diving, snorkeling, and island-hopping.     Head of the NTT tourism office, Maurius Ardu Jelamu, previously expressed concerns over the supposedly stressed-out komodo dragons.     "I've received a lot of insight from foreign tourists, some from Singapore and Europe. When they visited, they saw how visit patterns were not managed well due to the high number of visitors in the park," he said.
