In a large rectangular room, there are four people: Jia, Kwame, Lucia, and Navin. The room has two solid partitions that reach from the floor to the ceiling and are placed parallel to each other, dividing the room into three equal sections. The partitions do not reach the walls, leaving a gap that allows a person to walk from one section to another simply by going around either end of the partitions. Jia, Kwame, Lucia, and Navin are each standing in different sections of the room:

- Jia is in the section on the far left.
- Kwame is in the middle section.
- Lucia is in the section on the far right.
- Navin is in the middle section, but at the opposite end of where Kwame is standing.

Given that each person can only see directly in front of them and the partitions block any line of sight across different sections, who can see whom? If Jia decides to move to the far right section where Lucia is, passing around the far end of the partitions so that she does not cross paths with Kwame or Navin, what changes about who can see whom? Additionally, if Navin then decides to follow Jia by walking around the same end of the partitions and enters the rightmost section where Jia and Lucia are, who is visible to Kwame? Provide a brief response.
As the room is divided by two solid partitions, Jia cannot see any of the other three as she is in the far left section, and the partitions block her view. Kwame and Navin are in the same middle section, but they are standing at opposite ends; thus, they cannot see each other either because of their position. Lucia, in the far right section, is also isolated visually by the partitions and unable to see any of the others.

When Jia decides to move to the far right section where Lucia stands, she moves around the end of the partitions and therefore remains out of sight of Kwame and Navin throughout her traverse. Upon entering the far right section, Jia becomes visible to Lucia since they are now in the same open space. Kwame and Navin are still unable to see Jia, as the partitions continue to obstruct the view.

Finally, if Navin follows Jia around the end of the partitions to the section on the right, Kwame remains in the middle section alone and now cannot see anyone, as Navin has also moved to the section where Jia and Lucia are, and the partitions block all lines of sight between different sections. In the far right section, Navin would become visible to both Jia and Lucia, and they would be visible to him once he enters. Therefore, in the far-right section, Jia can see and be seen by both Lucia and Navin, Lucia can see and be seen by both Jia and Navin, and Navin can see and be seen by both Jia and Lucia. Kwame, now on his own in the middle section, cannot see any of the others.
