Answer:
I tried to picture those hands sowing seeds long ago, when Grandfather and the other Wampanoag people lived in Massachusetts.
Explanation:
This is the detail that most clearly gives this passage a reflective tone. In these lines, the author talks about his grandfather, and the stories he use to tell. We learn that the grandfather is Native American, and the stories cause the speaker to reflect on the past of these people and the experiences that they have gone through.
