You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task, we ask you to write an answer to a question about the events that may happen before or after a certain event. For example, "earning money" usually appears before "spending money". Note that a lot of the questions could have more than one correct answer. We only need a single most-likely answer. Please try to keep your "answer" as simple as possible. Concise and simple "answer" is preferred over those complex and verbose ones.
