Question

When testing a plugged-in but partly disassembled toaster, you should push the rack down with a

a. wooden stick.
b. piece of wire.
c. finger.
d. narrow wrench

Answer 1

A wooden stick would be best.
The wire and the wrench are both metal and therefore are able to conduct electricity.
Using your finger is obviously dangerous.
Wood is not a conductor so it is the best answer.
