" I read the book but i have short term memory."
Well, at least you remembered the title.
The trick to tackling question like these, is to relay the question in the answer.
For example..
"What is the setting of the story? "
The setting of the story is a historical/modern/newage/ one, where.... blah blah. The time setting resembles... I know this because ....
The problem the characters face in the book is.....
"Who are the main characters?"
Now even someone with short term memory could know that!
Good luck.. and use this to learn how to answer these questions, so you can tackle them yourself in the future.
As i've said.. i've not read the book, so i can not help you.
