Jay uses various objects to complete a circuit. He compares how bright a bulb glows using each object. His results are shown here.

Which object is the BEST electrical conductor?

• nail

• eraser

• crayon

• pencil lead

The circuit in this picture has a battery, a light bulb, and three switches. All of the switches are open, and the light bulb is off.

Which of these combination of switches could be closed and cause the light bulb to remain off?

• X and Y

• Y and Z

• X and Z

• X, Y,, and Z
