This question needs to be looked from two perspectives.
The first perspective is that of the characters from the book, The Giver, themselves. From their perspective it is possible as we can see from the novel when they almost showed no emotion to the news that Gabe will be released. This is due to the circumstances of the book where everyone is thought to be detached and they do not even understand the concept of love. Only Jonas gets attached to Gabe.
Second is our own perspective and it is nigh impossible for a person not to get attached to a baby for whom it is caring at least a little bit. The emotional attachment develops quickly for almost all of the people. So the contract in the real world probably would not work at all.
the answer is A - lost in the woods
The difference is the money
This question refers to Chapter 17 of <em>The Catcher in the Rye</em>. In this story, Holden and Sally are a couple. However, it is clear that, although they share some sort of bond, the two are not deeply in love, and at times, do not even like each other. Nevertheless, Holden is eager to do something to change his life, and decides to ask Sally to run away with him.
Sally does not entertain this notion at all. However, she still listens to Holden's plan. He wants the two of them to run away immediately. He tells Sally that he has saved $180, and that, with that money, they can stay in the cabin camps for a while. Afterwards, he might get a job, they might get a house with a brook, or they might get married.
The plans are never particularly clear, and in the end, they do not amount to any concrete action.
