Final answer:
The feeling of the book carrying voices from the past can be found in old letters and diaries.
Step-by-step explanation:
The answer is c) Old letters and diaries. In the given excerpt, Naomi describes the book as feeling heavy with voices from the past. This suggests that the book holds a sense of history and carries the memories, experiences, and stories of the people who have interacted with it. Similarly, old letters and diaries can evoke the same feeling as they provide a glimpse into the lives and thoughts of previous generations, capturing their voices and preserving their stories. These artifacts connect us intimately to history, preserving the essence of human existence across generations, and allowing us to hear echoes of the past through their pages.
