Worked Solution

Step 1: For current to flow, batteries must be arranged in a continuous direction (positive to negative). Step 2: If the same poles (e.g., + to +) face each other, the voltages oppose each other. Step 3: This results in no current flow.

Correct answer: The batteries were connected with positive poles facing each other.
