Task: Question Answering
Input (English): Passage: I had to change a light bulb on a light fixture on the ceiling of the den . I got my ladder from the garage and carried it to the den . I made sure the light switch on the wall was in the OFF position .  I set up the ladder under the light fixture and made sure the ladder was secure .  I unscrewed the light bulb by turning it to the left and removed it from the socket . I carefully climbed down the ladder and took the light bulb to the cupboard in the garage where I keep spare light bulbs . I chose a similar light bulb to the one I had just retrieved and took it to the den .  I climbed up the ladder with the new light bulb and screwed it into the socket by turning it to the right .  I made sure that the light bulb was screwed in correctly .  I then carefully climbed down the ladder and turned on the light switch to check to see if the new bulb lit up .  I then put the old light bulb in a box to be recycled . Question: What did they close up? Option1: the ladder Option2: The light fixture.
Output (English): the ladder
