Task: Question Answering
Input (English): Context: My sister works as a junior doctor in Edinburgh , and this week she had to call Kew Gardens to ask them to i d some mushrooms as they were treating a woman who had eaten some whilst out for a walk and was now violently ill . It all turned out okay , but I had no idea that Kew offered such a good service . I have to admit that I think that mushrooms and toadstools are just about the cutest things in the world ever , and have been meaning to crochet up some for ages . 
Question: Why did a woman eat mushrooms when she was out for a walk ?
Output (English): Because she thought they would be safe to eat .
