Task: Question Answering
Input (English): I saw a bust of someone standing in the middle but didn't stop because I was in a hurry to take pictures of the school , afraid that it will be too dark for good photos when the night approached . All the offices and classrooms were closed . I was walking along the quiet corridor when I saw a notice board saying " Working Class . No entrance " Perhaps that's a late class . 
Question: Why was the writer in a hurry to take photos ?
Output (English): Because soon it would be too dark .
