I'd like to remind members that this site is called The AnswerBank and here we don't make members feel bad for asking questions - and certainly not members who may be children. If you're not going to be helpful or if you're going to be rude, don't answer.
Having said that, Noa, you'll be more likely to get help from people here if you show that you've already put some effort into what we assume is your homework or coursework, and you are asking because you are still struggling. Being more specific about exactly what part of the question you need help with, what you've managed to do so far - and stating that you have actually read the book - may bring you more helpful answers.
