In the book the giver what does jonas learn about "releasing" while he is volunteering?

Answer:Jonas learns that releasing is not what he always thought.

Explanation:

"Releasing" as it is used in the book The Giver by Lois Lowry, is something that the society he lives in does with the elders after they have reached a certain age. The citizens are told that they go somewhere else, but in reality the patients are given a serum which in turn kills them silently.
