In this task, based on a given sentence, we ask you to write a question that involves the ordering of events, i.e., the understanding of how events are usually ordered. For example, "earning money" usually appears before "spending money". Don't create questions which have explicit mentions of answers in the text. Instead, it has to be implied from what is given. In other words, we want you to use "instinct" or "common sense". Note that the written questions are not required to have a single correct answer.
