Given a paragraph about movies, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.
One 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. <sep> FOLLOWUP_Q: Why has it been diminished?
Solution is here: King Joffrey is dead, and his younger brother Tommen is now king.
Explanation: The answer why Cersei's power over Margaery has now diminished is clearly mentioned in the passage.

Now, solve this: CONTEXT: Because Sam was their top earner and with the change in casinos after their trial, they kept him around to keep earning. He had already proven himself during his previous trials about his license and not only that, he survived the bombing. This had two implications, first is that he wasn't like Nicky and the second, he had far too much press after he survived the bombing as he was the center of attention with the gaming board. They really couldn't kill him without proving they (the bosses) were involved.  <sep>  Q: Why was Sam "Ace" Rothstein spared by the bosses? A: Because Sam was their top earner and with the change in casinos after their trial, they kept him around to keep earning  <sep> FOLLOWUP_Q: The bosses decide to eliminate anyone involved or with knowledge of the skim
Solution:
He had already proven himself during his previous trials about his license and not only that, he survived the bombing
