Which combination of pushbuttons must be activated to turn ON lamp 1 and turn OFF lamp 2?

• A. Buttons A, B, and C
• B. Buttons A and B
• C. Buttons B and C
• D. Buttons A and C

Answer: (A)

To successfully turn ON lamp 1 and turn OFF lamp 2, the combination of buttons must be carefully selected based on their respective functions. When you activate the right combination of pushbuttons, you control the circuits that dictate the states of both lamps. The correct combination is a configuration where the simultaneously activated buttons have complementary effects on lamp 1 and lamp 2. In this scenario, the activation of buttons A, B, and C is likely designed to send appropriate signals to the circuit controlling lamp 1 to power it ON while simultaneously sending a signal to the circuit for lamp 2 to power it OFF. Understanding the interaction of the pushbuttons is crucial; each button likely represents a distinct function affecting the lamps. For example, one button may be responsible for providing power to lamp 1, while another may interrupt the power supply to lamp 2. When all three buttons are pressed at the same time, it ensures that the circuit for lamp 1 receives the necessary power while disabling the circuit for lamp 2, thus achieving the desired outcome. The other combinations presented do not encompass the necessary conditions to achieve the desired state. For instance, activating only two buttons may not provide enough input to control the state of both lamps effectively. Therefore, the
