What did Peak realize about Josh's letters after learning that mail could be received?

• A. Josh had received every letter over the years and had not returned any.
• B. Josh had never received any letters.
• C. Josh had burned the letters.
• D. Josh had moved away.

Answer: (A)

Understanding how mail delivery works in this situation helps here: Peak discovers that letters can indeed reach Josh, and that over the years he has received each one but never sent a response. That makes the option about Josh having kept every letter and not returning any the most consistent with what Peak realizes. It shows that the letters were arriving and accumulating, not that no letters existed or that he burned or moved away. The key point is that the letters were delivered and kept, while there was no reply in return.
