What does Lily say about people having steel plates in their head?

• A. They forget their memories.
• B. They try to keep the sad thoughts away.
• C. They cannot think at all.
• D. They remember every detail.

Answer: (B)

Lily’s line uses a metaphor to show how people try to shield themselves from painful thoughts and feelings. When she says others have steel plates in their heads, she means they build emotional barriers to keep sadness from surfacing. That’s why the best choice is that they try to keep the sad thoughts away—it's about suppression of painful emotions, not about literally forgetting everything or being unable to think.

This isn’t about forgetting memories completely, being unable to think, or remembering every detail. It’s about avoiding and dulling the impact of sorrow, which fits Lily’s observation of how adults cope with hurt.
