question: Our assignment was to dial up the electric stimulation and measure how high the current needed to go at a given frequency in order to establish sensory threshold ( when you first begin to feel a tingle ) and motor threshold ( when muscles first begin to twitch ) . We started with 2 Hz which is two pulses per second . Then we delivered 25 Hz or 25 pulses per second . Finally , we went up to 100 Hz or 100 pulses of electrical stimulation per second .

OPTIONS:
- They are testing out current frequencies on the human body .
- They are testing out how to electrocute someone .
- They are testing out electric currents on muscles .
- None of the above choices .
Q: What might be a fact about what they are testing ?
