Task: Question Answering
Input (English): Passage: I was reading a great book in my favorite chair when suddenly the light went out . I flicked the switch on my reading lamp , but it did me no good . It looked like that light bulb had burned out . I went to the hall closet and poked around , and luckily I found just what I needed , a package of light bulbs just like the one that had burned out . I brought one of the new bulbs back to the living room , and unscrewed the old used-up light bulb . I put it on the kitchen counter so I would see it in the morning and remember to recycle it at our city 's transfer station . The light shone bright and clear . I settled back into my chair with a sigh , and opened my book again . Question: When did they screw the new lightbulb into the light socket? Option1: before unscrewing the old used-up light bulb Option2: after unscrewing the old used-up light bulb
Output (English): after unscrewing the old used-up light bulb
