In this task, we ask you to write an event that is not likely to happen after a certain event or is not likely to have happened before it. Pay attention that you will be asked the correct question, and you need to answer it incorrectly. For example, "earning money" usually appears before "spending money". Even though there exist multiple wrong answers, we only need a single wrong answer. Please try to keep your "answer" as simple as possible. Concise and simple "answer" is preferred over those complex and verbose ones.
