Answer:
The main events in Rikki-Tikki-Tavi are as follows:
1. Rikki-Tikki-Tavi is a mongoose who is adopted by a family living in India.
2. He discovers that the garden is infested with two cobras, Nag and Nagaina, who are determined to kill the family.
3. Rikki-Tikki-Tavi bravely fights the cobras and defeats them, saving the family from danger.
4. He then goes on to fight and defeat a dangerous snake called Karait, who had been terrorizing the village.
The complications that make it hard for Rikki-Tikki-Tavi to reach his goals are:
1. The cobras are much larger and more powerful than Rikki-Tikki-Tavi, making it difficult for him to defeat them.
2. The cobras are also very cunning and use their intelligence to try and outwit Rikki-Tikki-Tavi.
3. The cobras have allies in the form of other snakes and animals, which makes it harder for Rikki-Tikki-Tavi to fight them alone.
4. The cobras also have access to a secret underground tunnel which they can use to escape from Rikki-Tikki-Tavi if necessary.
