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 theme of Christina Georgina Rossetti's poem "Helen Grey" is, beauty isn't everything. We know this to be true because the Rossetti describes Helen Grey as "handsome" and "proud" but also says "But so you miss that modest charm / Which is the surest charm of all." This shows the reader that Helen Grey is very attractive and takes pride in her attraction. However, she has let her beauty go to her head, resulting in an unpleasant personality that no man has found her attractive. The last four lines of the poem "Helen Grey" support the its main theme by drawing the reader's attention to the reality of age and time. Time will continue to go by causing Helen to grow old, wrinkly, and gray. Time will pass and with it, Helen's beauty shall pass too. If she does not change her ways, she will be left with and unattractive personality, and face.
The people will have journeyed to the center of the earth. I think this because it is the title. This is fantasy because the center of the earth is too hot to travel to. The people will probably get burnt next.
