What evidence supports the idea that Bobby moved into Jamie's neighborhood?

The choice indicating that Jamie can see Bobby driving from his front yard provides direct evidence of Bobby's presence in Jamie's neighborhood. This observation suggests that Bobby is now a resident close enough for Jamie to notice when he is driving by, indicating a physical move into the area. The visibility from Jamie's front yard implies a level of proximity that aligns with the idea of Bobby having moved nearby.

The other options do not provide clear evidence of Bobby's move into the neighborhood. Receiving a letter does not indicate his location; their childhood friendship does not relate to their current residences, and frequent visits to Bobby's house would imply that Jamie is visiting rather than Bobby living in the neighborhood. Therefore, seeing Bobby driving is the most compelling evidence supporting the idea that he moved into Jamie's neighborhood.
