Question

Ana was setting up a circuit to make a buzzer buzz. She didn’t have any wires, so she needed to find

something that had the same properties as wires. Which of the following would work for Ana’s circuit?
A. A steel knife
B. A wood chopstick
C. A plastic straw
D. A glass tube

Answer 1

should be a or d, though im leaning towards d more. sadly can't narrow it down 100%. b nor c are correct since they are made out of wood and plastic which cannot allow electricity to pass by. copper and metal are effective conductors of electricity, which a steel knife and a glass tube is made out of.
