Nasira and Takeshi are in a room with a blue box and a red box. Nasira hides her watch in the blue box and then leaves the room. Takeshi moves the watch from the blue box to the red box and then also leaves. Later, Marisol enters the room and accidentally knocks over the red box, and the watch falls out. Marisol, unaware of whose watch it is, places it on a shelf and exits the room. If Nasira returns looking for her watch, where will she first look for it and why might she be confused when she doesn't find it there?

Respond very briefly.
Nasira will first look for her watch in the blue box because that is where she left it, and she has not seen or been informed of any of the changes that occurred after her departure. Upon not finding her watch in the blue box, Nasira may initially be confused because, according to her knowledge, that's the last known location of her watch. Not aware of Takeshi's or Marisol's actions, she lacks the information to understand why the watch is not in the blue box and might consider other explanations such as misremembering where she placed it or pondering the unlikely event of someone else discovering and moving the watch. Without evidence of the intervening events, the correct location of the watch on the shelf is unpredictable to her, and it would take further searching or new information to resolve the confusion about the whereabouts of her watch.
