Sarah, Jane, and Tom live together in an apartment. One day, Sarah buys a carton of milk and writes her name on it before placing it in the fridge. Later that day, Jane accidentally spills half of the milk while making coffee and decides to replace it with a new carton without telling anyone. Meanwhile, Tom comes home from work and sees the new carton but doesn't notice the spilled milk. What does each person believe about the milk situation when they next open the fridge? Provide a short response.
Sarah believes the milk is as she left it because Jane replaced the spilled milk with a new carton and Sarah hasn't been informed of any changes. Jane knows that the original milk was spilled and has been replaced; she is aware that the new carton is not the one Sarah put in the refrigerator. Tom, having not witnessed any of these events and seeing a milk carton with Sarah's name on it, assumes that the milk situation is unchanged and that the carton contains the milk Sarah bought.
