Given the task definition, example input & output, solve the new input case.
Turn the given fact into a question by a simple rearrangement of words. This typically involves replacing some part of the given fact with a WH word. For example, replacing the subject of the provided fact with the word "what" can form a valid question. Don't be creative! You just need to rearrange the words to turn the fact into a question - easy! Don't just randomly remove a word from the given fact to form a question. Remember that your question must evaluate scientific understanding. Pick a word or a phrase in the given fact to be the correct answer, then make the rest of the question. You can also form a question without any WH words. For example, "A radio converts electricity into?"
Example: Fact: pesticides can harm animals.
Output: What can harm animals?
It's a good question because it is formed by simply replacing the word "pesticides" with "what".

New input case for you: Fact: techniques used to precisely control the output control insulin secretion.
Output:
techniques used to precisely control the output do what?
