Task: Question Answering
Input (English): Context: Because he did n't . As he thought all this , he realized his hand was still on her , lightly touching the skin at the edge of her uniform .

Instead he flattened his hand , letting his whole palm feel her heart pounding . 
Question: Why did he choose to step between and separate the people fighting ?
Output (English): He stepped in because he was concerned about the one person who was fighting .
