How does Milo get a sound out of the Soundkeeper's fortress?

• A. By clapping.
• B. On the tip of his tongue.
• C. By singing.
• D. By knocking on the door.

Answer: (B)

The idea being tested is how sounds are released in the story: sounds are stored and must be spoken to be freed. The moment uses a common expression about speech—the sound is “on the tip of his tongue,” meaning it’s ready to be spoken and released with a small articulatory push of the tongue. In the Soundkeeper’s fortress, Milo frees a sound by saying it, not by clapping, knocking, or singing—those actions create sound themselves but don’t release a specific stored sound. So the best answer captures that the sound is ready to be spoken and can come out with a simple utterance.
