5. Two wires carrying electricity can create a spark if they come too close together. This spark can start a fire. Wires carrying electricity are usually covered with plastic to keep them from starting a fire. Why does covering wires with plastic help prevent them from starting a fire?
a)
A.) Plastic makes the wires stronger.
b)
B.) Plastic makes the wires cooler.
c)
C.) Plastic keeps the electricity from escaping.
d)
D.) Plastic acts as a barrier to prevent the wires from touching.
