Teacher: Given a paragraph about movies, and a set of conversational question answers about the paragraph, generate a relevant question to the topic of the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`.
Teacher: Now, understand the problem? If you are still confused, see the following example:
CONTEXT: The balance of power had shifted considerably since the first set of quotes. King Joffrey is dead, and his younger brother Tommen is now king. Unlike his wild card of an elder brother, Tommen is gentler and more prone to manipulation by his new bride. The Lannisters impeccable image has also been shattered. They failed to prevent the assassination of their king in the midst of his own wedding day, and the suspected assassin is the king's Lannister uncle. Not only do they look incompetent, they are divided among themselves. On the other hand, the Tyrells' situation is much stronger now. Tommen is already wrapped around Margaery's pretty little finger, and she knows that the assassination was orchestrated in part by her own family. In Margaery's eyes, the Lannisters look disoriented and lost. Putting on a show trial for one of their own, whom she knows is innocent of any wrongdoing. Whatever power Cersei held over Margaery has now been diminished. <sep>  Q: What was Margaery's motivation to call Cersei 'sister' again? A: Whatever power Cersei held over Margaery has now been diminished.
Solution: Why has it been diminished?
Reason: The question is valid since it is on the same topic and a follow-up of the previous answer in the conversation. The question asks about the reason why the power held over Margaery by Cersei have diminished.

Now, solve this instance: CONTEXT: Ben could've escaped whenever he wanted, he wanted to ensure that Dan sees him off in the train to Yuma, The reason being he wants Dan to succeed in his endeavor because of the promise he made to his son and his wife and also he sympathizes with Dan on the fact that he used to be a soldier and his life changed after he sustained the injury in the war and wanted to give him the fulfillment of sending the notorious criminal to the jail. So when Charlie kills him against his orders Ben gets angry on that issue and he no longer cares for the group and he kills them all and goes in the train simply to fulfill Dan once again and once the train departs he flees on his horse.  <sep>  Q: do you think he chose to help him out of guilt? A: he sympathizes with Dan on the fact that he used to be a soldier and his life changed after he sustained the injury in the war 
Student:
that sounds about tight, so you think even mass murderers can change?
