What's in a Breadboard? continued...

From the website Sparkfun: An LED inserted into a breadboard. Notice how each leg of the LED is placed on either side of the ravine. This prevents the connections to the LED from being shorted.

Questions

Please answer the questions below.

How is it possible that putting the legs of an LED bulb in pins across the "ravine" from each other does not result in a short circuit (the LED bulb will light)?

The metal strip is connected across the ravine, so the circuit can complete itself.
The metal strip is connected across the ravine, so the current is forced to go in one side of the LED and out the other.
The metal strip is not connected across the ravine, so the current is forced to go in one side of the LED and out the other.
The metal strip is not connected across the ravine, so the circuit cannot complete itself.

Would the LED bulb light if the prongs were put in different rows?

Yes, as long as the edges of the prongs are not connected with a metal strip, the current will not short circuit and the bulb will light.
No, putting the prongs in different rows breaks the circuit and does not allow current to flow.
