Task: Question Answering
Input (English): Context: My hair was such a knotted monster that after spraying nearly a quater of a bottle of detangler on it the poor hairdresser resorted to just cutting the knots out , which was needless to say a lot more then the two inches I told her to . But it looks nice , and it 's so light and so very knot free . I should n't complain . 
Question: Why did I spray nearly a quarter of a bottle of detangler on it ?
Output (English): Because I wanted it to become untangled .
