In an office, there are three coworkers: Emily, Frank, and George. They all share a common refrigerator to store their lunches. One day, Emily brought a sandwich wrapped in green foil and placed it on the top shelf of the fridge. While she was away from her desk, Frank accidentally knocked over a container of juice, spilling it all over Emily's sandwich. He quickly cleaned up the mess and replaced her ruined sandwich with one he bought from the cafeteria, wrapping it in red foil. When Emily returns to get her lunch, what will she think happened to her sandwich? Provide a very brief response.
When Emily returns to get her lunch, she will notice that her sandwich is now wrapped in red foil instead of the green foil she used. Since she was not there to witness Frank's accident or him replacing the sandwich, her first thought might be that someone took her sandwich and replaced it with a different one. Without knowing Frank's involvement, she could assume there was some mix-up or possibly think someone stole her sandwich and left another in its place. Without additional information or a note from Frank explaining the situation, Emily would be left to guess what happened to her original sandwich.
