Observe the diagram. How many bulbs would turn on if a student closed switch C and switch D?

• A. 0 bulbs

• B. 1 bulb

• C. 2 bulbs

• D. 3 bulbs

Study the picture carefully. A student designed the circuit shown. What would most likely happen if the student closed Switch 1, Switch 2, and Switch 4?

• F. Bulb A would light up and the bell would ring, but Bulb B would not light up.

• G. Bulb B would light up, but Bulb A would not light up and the bell would not ring.

• H. Neither of the bulbs would light up, and the bell would not ring.

• J. Both of the bulbs would light up, but the bell would not ring.
