I can't really help because I did not read the story. they want you to describe how the tiger was representing Rob in the story so go back in the book and read some paragraphs to get ideas.
Yes, there have been many times when you have to lie to get out of a situation. For example, I remember a time when I was being asked humiliating questions by a total stranger, so I lied and said that I had to go due to family issues including my mother. It is okay to lie in uncomfortable situations.
