Task: Question Answering
Input (English): Passage: I took swimming classes as a kid in an indoor pool . First I would get changed into my swimming trunks and store my regular clothes in a locker at the pool . Then I 'd carefully walk to where my instructor was in the pool . It was important to walk slowly because if you ran there would be a higher risk of slipping on water that got outside the pool . Then I 'd hop into the water and start treading around to keep myself afloat as I got warmed up and awaited instructions . Then I would try to replicate the motions slowly and deliberately . Then I 'd go back and forth the length of the pool a few times practicing the stroke , dive , or movement . At the end I 'd have fun jumping off the diving boards . Question: They watched the instructor as they demonstrated a stroke and listened to who explaining the technique? Option1: Themselves. Option2: The instructor.
Output (English): The instructor.
