Answer:
If you turn off one light bulb, then the others would go out. If one burns, the others burn, too. Do an experiment.
Step-by-step explanation:
All household electrical circuits are wired in parallel with each other; there's nothing special about fluorescent lights. This is so that the full 120 volts is presented to each device. If you put devices in series, they will "share" the voltage, say 70 volts to one device and 50 volts to the second (adding up to the 120 volts in the circuit).
