Worked Solution

Step 1: Standard MOE circuit symbols: Circle with X is a bulb; parallel lines are a battery. Step 2: A switch is shown as dots and a line. If the line is slanted up (not touching the other dot), it is open. Step 3: Open switches break the circuit.

Correct answer: A line slanted upwards from one dot
