Did you read giver?
Why does the Nurturing Center release one of every set of identical twins?
a) The staff is sadistic
b) It is inconvenient to have identical people walking around
c) They need to practice their releasing techniques
d) One twin is always seriously ill at birth
i have read the book and the movie, the answer is B) they wanted a perfect society and 2 identical people walking around would be confusing, so they weighed the babies and the heavier one lived and the lighter one was released
