What's in a Breadboard?

Take a look at your breadboard. Gently pull back a little tab of the sticky backing to observe what's underneath. (Do not take the backing off! Only peel a little bit.) Here's what's underneath:

You should see metal strips below the sticky backing. The pin holes on the front of the breadboard allow any wires you stick in the holes to touch the metal strips on the back.

Questions

Please answer the questions below.

Look at any row on your breadboard (let's say, row 12). What would happen if you put the two legs of an LED bulb in pins next to each other in the same row (row 12)?

The LED bulb would light, because the current is forced to go in one leg of the LED bulb and out the other.
The LED bulb would light, because the metal strip allows current to skip the LED bulb and go quickly through the metal strip instead (short circuit).
The LED bulb would not light, because the current is forced to go in one leg of the LED bulb and out the other.
The LED bulb would not light, because the metal strip allows current to skip the LED bulb and go quickly through the metal strip instead (short circuit).
