Task: Question Answering
Input (English): I ran out into the hallway , and joined a crowd going down the stairs . At the third floor , someone at the front of the crowd started saying we couldn't get out . I shouted that we should at least go down and try : it's better than standing in the stairwell . At the second floor , a woman was holding the stairwell door open , gesturing for us to follow . The student lounge was jam - packed , the wide - screen tv was turned on to CNN . 
Question: Why were these students locked in ?
Output (English): There was an emergency going on at the school .
