Give one or two scenes in the novel that deal with the idea of self sacrifice for the benefit of the group.

One example of scacrifice can be found on pg. 144, when Minerva asks the others to put her bed on the floor of the barn, while the others sleep in the loft. In this way, she is the only one taken by the Recruiters... she scarifuces herself, so that those she sees as her family will stay safe.
