Task: Question Answering
Input (English): Passage: Last night my mom started choking while we were eating and she could not breath . My little brother and I noticed that she was turning blue and we got very afraid . I remembered the special class at school about calling 911 in an emergency , so I called 911 . I told her that my mom was choking and turning blue and we needed help . The nice lady , her name was Mary , asked me how old I was and if I knew my address . I felt stupid because I could only remember the street name and the city I lived in , but Mary said to calm down and she would help me . Mary told me to stay near my mom until the ambulance came and open the door for them as soon as I saw the lights , so I did . Luckily the men from the ambulance squeezed my mom real tight from behind and she spit up the food she was choking on , it was gross . I never got to talk to Mary again , but she helped a lot , I am very thankful for 911 . Question: When did they call 911? Option1: after the ambulance came Option2: last night
Output (English): last night
