My questions and answers about the plot of the book.

Sometimes when you open a new book, there are some questions about a plot. Now I'll try to answer some of them.

1) Did Pi became mad, because of the mental diversion "escapism" by means of entertainment or recreation, as an "escape" from the perceived unpleasant or banal aspects of daily life?
I think he wasn't mad, that was a normal reaction to the situation he had, because trying to remove themselves from the rigors of daily life and replace the harsh realities on fiction and fantasy was the only way out not to have a persistent feelings of depression or general sadness and to be aside from the problems.
2) Why does the tiger have such a strange name Richard Parker?
There are a number of strange coincidences with the name Richard Parker:in the book of Edgar Allan Poe's "The Narrative of Arthur Gordon Pym of Nantucket," published in 1838,there is a sailor Parker who survived after the crash of his vehicle  with three other members of the team, but they ate him, not to die of hunger. In 1884, a ship called Mignorette has sunk in the ocean, and only four people were rescued, among them there was the cabin boy named Richard Parker, who was later killed and then who was eaten by the other three survivors. Yann Martel, the author of the novel "Life of Pi", named a Bengal tiger "Richard Parker", because of these events.
3) What was the the cause of shipwreck?
It's impossible to know the certain reason of the crash, but probably the ship could encounter with floating debris.
4) Why the main hero pulled out  the net and didn't take bananas?
He took the net mechanically but later it was useful for him for fishing.
5)Did Pi run wild in the absence of comfortable conditions?
In my opinion, this story makes us think if people differ from wild animals in such case when they don't have to wear clothes and when they are kept away from ready meals. After all, Pi realized that he became wild when he heard his  growl eating fish which was not very different from Richard Parker's growl and he was wild because the clothes after  a few months was completely torn.
6)Why Pi didn't kill the tiger to still hunger?
The compassion, responsibility which Pi expressed in relation to the tiger showed that he would never  kill him, and even on the contrary he  feeded him and took him to the shores of Mexico, as he had promised him that they would survive, the courage that he has shown in all that time without losing self-control gave us the understanding what noble-minded knightly nature he had.
