What is the holy book of your faith, and how does it compare to others

This is specific to your religion of preference. I can not answer this for you, however, I can explain it a little bit. They are asking you to compare your religion's (faith's) holy book to that of another religion's book, for example if you are a Christian your holy book is considered the "Holy Bible" and you would compare the principals and similarities of that book to the book of Torah (Judaism), or Tripitaka (Buddhism), or Quran (Islam) Its really up to you, all you need to do is compare your holy book to others (if you don't have one just use one that you know best and compare it to others) 
There are a lot of religions out there you would be surprised, look some up online it will help.
