Task: Question Answering
Input (English): Context: I was walking up to our mailbox when coming home one evening . To get to it , I have to walk through a small dirt walkway . Well , it 's not really a walkway , but I 'd rather step on that and duck under trees instead of walking on the lawn . I noticed that the heels on my new shoes were sinking in as I walked . 
Question: Why was the brand new shoes ruined ?
Output (English): The lawn was dirty .
