In a large clothing store, Nia is working as a sales associate in the women's section. This area is specifically designed with multiple changing rooms arranged in a semi-circular formation. Each changing room is separated by a curved partial partition that doesn't reach all the way to the ceiling or floor, allowing for some visibility towards the ceiling and floor areas shared between two changing stalls. The partitions are designed with a translucent frosted material that obscures clear view while letting light pass through. At the entrance of each stall is a curtain, rather than a door, which can be pulled closed for privacy but doesn't seal the stall completely on the sides.

Qasim is the store's security officer who is currently standing at a vantage point near the women's section, where he has a clear line of sight to the entrance of the changing area but cannot directly see into the stalls. His position is strategically chosen so that he can monitor the flow of customers going into and out of the changing area, as a measure against theft, but also to preserve the privacy of the customers within the stalls.

On a busy afternoon, Ga-Eun enters the changing area with several pieces of clothing to try on. She picks a changing stall in the middle of the semicircle and pulls the curtain closed behind her. After a moment, Saoirse enters the changing area as well and chooses the stall adjacent to Ga-Eun's, separated by the frosted partition. 

As Ga-Eun is trying on clothes, she accidentally drops a bracelet which rolls under the partition into Saoirse's stall. At the same moment, Saoirse is standing on a bench in her stall, adjusting her dress in the mirror that is mounted high up on the partition wall.

Considering the setup of the changing area and the positions of Qasim, Nia, Ga-Eun, and Saoirse:

1. Can Ga-Eun see Saoirse as she stands on the bench without Saoirse noticing her?
2. When Ga-Eun's bracelet rolls into Saoirse's stall, can Qasim see this from his vantage point?
3. If the bracelet rolls far enough to reach the curtain entrance of Saoirse's stall, could Nia, who is walking by the entrance of the changing area, potentially see it without entering the stall area?

Provide a brief response.
1. Due to the frosted partitions between the changing stalls being designed to prevent a clear view, Ga-Eun cannot directly see the majority of Saoirse's actions. However, since the partitions do not stretch all the way to the ceiling, Ga-Eun might catch a glimpse of Saoirse's reflection in the high-mounted mirror from Ga-Eun's position if she looks up. Moreover, with Saoirse standing on the bench, part of her may be above the top of the partition, depending on her height. But since Saoirse's attention is focused on adjusting her dress and the partitions are designed to obscure the view, it is unlikely that Saoirse would notice Ga-Eun unless she actively looks over the top of the partition into Ga-Eun's stall.

2. From the description, Qasim's point of view allows him to monitor the entrance and exit of the changing area for security purposes, not the inside of the stalls. Therefore, even if the bracelet were to roll under the partition, Qasim would not be able to see this event from his location. He is positioned to respect the privacy of the customers, and the line of sight to the floor level of the stalls would likely be obstructed by the semi-circular arrangement and the partial curtains at the entrances. 

3. As for Nia, given that she is walking by the entrance of the changing area and the curtains do not seal the stalls completely, she may catch sight of the bracelet if it rolls far enough to extend into the gap at the entrance of the stall. This would be more likely if the curtain is not fully closed or if the bracelet has enough momentum to push against the curtain, creating a subtle motion that might catch Nia's attention. However, her ability to see the bracelet also depends on the transparency and the gap size of the curtain entrance as well as the level of attention she is paying to her surroundings while she passes by.
