Which answer would score higher? Not sure where to start? Explain this Answer A The A-circle is an ammeter, the rectangle a resistor and the separated lever an open switch. One pairing is correct, so 1 ÷ 3 × 100 = 33%. Answer B The A-circle is an ammeter, the rectangle a resistor and the separated lever a closed switch. Two pairings are correct, so 2 ÷ 3 × 100 = 67%.
