You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
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.

Sentence: Jack played basketball after school, after which he was very tired.
Solution: How often does Jack play basketball?
Why? "Playing basketball" typically happens few times (1-7) per week, so it is a "frequency" question.

New input: Sentence: A plant uses a lot of energy to produce nectar.
Solution:
How often do plants use energy to produce nectar?
