 1.electric current will flow through the circuit because the toothpick is a conductor. 
 2.electric current will flow through the circuit because the toothpick is an insulator. 
 3.electric current will not flow through the circuit because the toothpick is a conductor. 
 4.electric current will not flow through the circuit because the toothpick is an insulator.
