Answer 2

the best answer will be is D “[The] bulb did not glow for long, however. It produced light for only thirteen hours.” Because, Swan's light bulb didn't last as long as Edison's and required more current to operate at the same power level as Edison's. Higher current meant you need thicker wire to power it. Good Luck! I hope this helps!!!
