Which detail from the article provides the best example of the central idea in Part A?

• “In a normal electric circuit, an electric current powers an appliance, such as a refrigerator or TV.”

• “Every such appliance has a certain amount of resistance to the current flow, which keeps the current from reaching very large values.”

• “Although houses today often contain circuit breakers rather than fuses, fuses are still around.”

• “. . . the wire in the fuse heats up quickly and melts, breaking the circuit and preventing a fire from breaking out.”

Which step of the experiment is repeated multiple times in “Short Circuit”?

• Use an alligator clip to attach a copper wire to a battery terminal.

• Attach one end of an iron wire to the other battery terminal.

• Use a second alligator clip to attach the other end of the copper wire to the iron wire.

• Shorten the distance between the second alligator clip and the battery.

A result occurs when the step is repeated in the experiment. Which phrase from “Short Circuit” shows the result of the repeated step that is the answer to Part A?

• “. . . deliberately chosen to have very low resistance.”

• “. . . voltage of the battery pushes electrons through the circuit . . .”

• “. . . more current flows . . .”

• “. . . which keeps the current from reaching very large values.”
