Passage: I went skiing in the mountains during my vacation from work . I had never been before . On my ski trip , I woke up early , ate breakfast , and put on my ski clothes . I wore a sweater , ski pants , a big jacket , a hat , thick gloves , goggles , and boots . I talked to the man at the lodge , who helped me rent skis and ski poles , and sign up for a lesson . I paid for the skis and went outside to the small hill . I put on my skis , and the ski instructor came outside and asked if I was ready to start my lesson . I was nervous , but I said yes . The instructor told me how I should position my skis , and how to start , go faster , slow down , and stop . It was scary but I 'm glad I went . Question: When did they skid down the hill by themselves? Option1: after the instructor gave them lessons Option2: when the rocks fell
after the instructor gave them lessons
