In this task, we ask you to write an answer to a question about when an event happened. For example, "going to school" usually happens during the day (not at 2 A.M). 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.
