Task: Question Answering
Input (English): Passage: I 'm not a great swimmer so every summer I take a swimming class and try to improve on some basic skills . Last time I signed up and paid for the class . Then when the class started I went to the pool with my bag full of pool gear . I made sure I had a rubberband for my long hair to tie it up , my swimsuit , goggles , kick board , flip flops , shampoo and conditioner , shower gel and a sponge and a few towels . In the locker room I put a quarter in a locker to open it up and I changed into my suit and tied my hair up . I walked out to the pool and found my teacher . The teacher checked to make sure I had everything I needed then said I could come in the pool and wait for the class to start . When the rest of the students were there we started class just by trying to put our face in the water . It was fun too ! I went to the shower and washed up then got dressed and went home . The locker kept the quarter as a fee for using the locker . Question: When did they lock the locker? Option1: after walking to pool Option2: after changing into suit
Output (English): after changing into suit
