Why does the Soundkeeper lock all the sounds up in her vault?

• A. She thinks people don't appreciate them
• B. She wants to catalog them
• C. She fears loud noises
• D. She runs a library

Answer: (A)

Sounds are valuable and deserve to be noticed, not just heard and forgotten. The Soundkeeper locks all the sounds away because she believes people don’t appreciate them when they’re around; locking them in a vault is her way of protecting and cherishing sound, hoping to keep its specialness intact. When Milo unlocks and releases them, we see how much we miss and value sounds once they’re gone from daily life. This explains why the chosen reason fits best. The other ideas don’t align with her aim—she’s not trying to catalog them, nor is she driven by a fear of loud noises, and she isn’t running a library.
