Given the task definition, example input & output, solve the new input case.
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:`.
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.
Output: Why has it been diminished?
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.

New input case for you: CONTEXT: The point is that it's not about being smart.. It's about knowing what you are talking about and and having the guts to hold a position. We see, in the scene prior to the elevator sequence, that the other CIA officials are all hedging their bets about the location of Bin Laden, Chastain's character is the only one who will commit to being certain. This is why, even though, all of them are smart... he discounts that as being the deciding factor. Being knowledgeable, and committed to an opinion, even an internally unpopular one, carries more weight with him Which is why, in the very next scene, the Director talks to Chastain's character to weigh her up for himself. He's convinced, not only by her certainty but by the fact that the only thing she's done for the CIA in her 12 years...is hunt Bin Laden.  <sep>  Q: What is the meaning of the elevator scene in Zero Dark Thirty? A: We see, in the scene prior to the elevator sequence, that the other CIA officials are all hedging their bets about the location of Bin Laden 
Output:
Why is she so certain?
