Answer: The given statement is false.
Step-by-step explanation:
It is possible that someone might forget to switch off the electrical socket and as a result, the person will accidentally receive an electrical shock.
Thus, we cannot say that electrical socket was left switched on to punish somebody.
Hence, we can conclude that the statement receiving an electrical shock when you forget to turn off the power before working on an electrical socket is an example of a negative punishment, is false.
