Electrons would easily move through the person if there was no rubber around the wire.
Explanation: The black rubber is an insulator that blocks current. The metal wire inside is a conductor that carries electrons. If the insulation were gone and a person touched the live wire while grounded, current would flow through the person and cause a shock.
