Teacher:In this task, we ask you to write a question that asks about "event duration", based on a given sentence. The question will likely start with "How long". Your question should be answerable based on the common knowledge of how long certain events usually last. 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.
Teacher: Now, understand the problem? Solve this instance: Sentence: Despite his quick climb up the legal ladder, Bailey has always found time to help out in causes he feels strongly about.
