Answer:
We must complete the blanks in:
"People can become part of a _______. When a person becomes part of an electrical______, that person can be shocked.
"
Suppose that you have an open circuit, now, if a person touches both ends of the circuit, now the circuit can be closed and the current can flow in this circuit, also flowing through the human body, putting in danger the life of the person.
This also can happen with closed circuits where the human body can be inserted, for example, this can happen when you touch a bare wire in an electrical thing, in this case your body is now another part of the circuit, and the current will flow into your body.
So the completed sentence would be:
People can become part of a circuit. When a person becomes part of an electrical circuit, that person can be shocked.
