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:`.
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?
Example solution: King Joffrey is dead, and his younger brother Tommen is now king.
Example explanation: The answer why Cersei's power over Margaery has now diminished is clearly mentioned in the passage.

Problem: CONTEXT: The biggest reason is that they weren't prepared for an attack. The Lannister army wasn't supposed to be there, but rather defending King's Landing and Casterly Rock. Lady Tyrell even goes on to say that fighting was never really the Tyrell's strong suit, so in-universe it wasn't a surprise that they fell so quickly. Also, wealth doesn't equate to army size. Just because the Tyrell's have a lot of money doesn't mean that they have a huge army. In fact, house Lannister is in significant debt because of it's huge army and all of the fighting they've had to do over the last few years.  <sep>  Q: How was a powerful house so easily defeated? A: The biggest reason is that they weren't prepared for an attack  Q: In GOT season 7 episode 3, we see the Lannister army invade and defeat house Tyrell in Highgarden. The fight was so one-sided A: The Lannister army wasn't supposed to be there, but rather defending King's Landing and Casterly Rock  <sep> FOLLOWUP_Q: Its established in season 7 episode 1 that the Lannister army is running short of supplies and money and house Tyrell richest house in Westeros.

Solution: Also, wealth doesn't equate to army size. Just because the Tyrell's have a lot of money doesn't mean that they have a huge army
