The question that would best be answered by an experiment is: "Does taking a pre-workout supplement increase the number of calories burned during a workout?"
This question involves testing a hypothesis by manipulating a variable (the intake of a pre-workout supplement) and measuring the effect on another variable (the number of calories burned), which is characteristic of experimental research.
