The fact "To understand the event "Frank dropped a glass of water.", it is important to know that Frank lost his grip on the glass of water he was holding in his hand." is illustrated with the story:1. If a glass of water is very cold and the room temperature is fairly warm, then condensation forms on the outside of the glass.2. If the outside of the glass is wet, it makes it more likely that you could drop the drink.3. If Franks hands were greasy from eating fried chicken then he'd lose his grip on the glass.4. If Frank was very hot and tired, this could also make him drop the water glass.
