Detailed Solution

The above statement is True.
We get an electric shock when electric current passes through our body to the ground when we touch the live wire.
If we are standing above a plastic or dry wood chair, then even on touching the live wire, we will not get any electric shock because plastic and wood are bad conductors of electric current and they break the circuit. Since the electric circuit is not completed the current will not flow at all and we will not get an electric shock.
