Explanation:
Initially the bulb was not glowing because one cell was not able to provide sufficient voltage to cause the current to glow the bulb.
When one more cell is added in the circuit the voltage across the circuit doubles and it becomes sufficient to increase the current. This current heat the filament of bulb sufficiently and bulb glows.

Answer:
✓ Addition of another cell increased the current through the bulb sufficiently to make it glow.
