Passage: The ceiling light in my kitchen started to flicker.It was time to change the light bulb . A new package of bulbs was in the junk drawer . Since I only needed 1 bulb I pulled it out and put the package back . I placed the bulb on the back shelf along with a paper towel . Of course , I made sure the light switch was off so I would not be shocked . I climbed the ladder and carefully unscrewed the cover , setting it down on the back shelf . The new bulb screwed in easily . I wiped the cover with my towel and screwed it back , as well . I climbed down the ladder , put it away and disposed of the bulb and towel.When I flipped the switch the bulb came on without a flicker . Question: What did they unscrew? Option1: the new bulb Option2: the light cover
the light cover
