Provided the input sentence, you're expected to write a question that involves event "frequency", which refers to how often an event is likely to be repeated. For example, "taking showers" typically occurs ~5 times a week, "going to Saturday market" usually happens every few weeks/months, etc. 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". Also, the written questions are not required to have a single correct answer.
Example: Sentence: Jack played basketball after school, after which he was very tired.
Example solution: How often does Jack play basketball?
Example explanation: "Playing basketball" typically happens few times (1-7) per week, so it is a "frequency" question.

Problem: Sentence: For example, what if you place a cake in the oven and you leave it in too long?.

Solution: How often do you leave cakes in the oven too long?
