Given a paragraph about movies and a set of conversational questions and answers about the paragraph, say whether the passage contains sufficient information to answer the follow-up question. Say Yes if it is answerable; otherwise, say No. 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:'.

[EX Q]: CONTEXT: Bran is believed to be dead. When Robb marches to war, Theon Greyjoy betrays the Starks and takes Winterfell. Bran and Rickon escape. Theon eventually has two boys slain at a farm and says that they were Bran and Rickon. As far as the greater world knows, all the Stark men are dead, which leaves Sansa (the oldest girl) as the heir to Winterfell. Whoever marries her will become Lord of that region. <sep> Q: Why is Sansa Stark so important?
[EX A]: Yes

[EX Q]: CONTEXT: SHIELD have been holding the Tesseract for a very long time since Howard Stark found it not long after Captain America went missing (close to World War 2). They have been studying its properties ever since. Also, Loki knows some of its power and secrets from Thanos as explained in the movie. Connect that with the slight influence Loki has over Selvig in credits scene for Thor. So Selvig probably has some breakthroughs in that research, maybe because of his own intellect and maybe because of Loki. The conclusion Hawkeye makes that "doors open from both sides" is just a guess, which is soon proven correct. But Hawkeye and Fury and Selvig are all in the same room a whole lot before this moment, studying the same thing basically. So it's safe to assume they all share any knowledge about that, at least in principle even though Selvig probably more deeply. <sep> Q: How does everyone know so much about the Tesseract? A: Loki knows some of its power and secrets from Thanos as explained in the movie Q: How do all of the Avengers know about the 'powers' of the tesseract? A: Hawkeye and Fury and Selvig are all in the same room a whole lot before this moment, studying the same thing basically. So it's safe to assume they all share any knowledge <sep> FOLLOWUP_Q: So, everyone knows that the Tesseract is powerful, yet, they don't know what it can do?
[EX A]: Yes

[EX Q]: CONTEXT: This has been unanswered for too long, so I'm just going to say it. NO. That is not him. Beyond throwing CGI money away on such an inconsequential shot, if you look at the other man's features you'll notice much different bone and cartilage structures around the eye sockets, more-centered zygomatic bones (cheekbones), and a more acute angle where the nasal bones indent and leave the brow. Plus, this man looks nothing like The Professor / Bernard Fallon (Borden's alter-ego). I see no reason to assume this is anything other than someone reading too much into a slight resemblance. Do I have definitive proof? No, I do not. Also, I have difficulty in seeing any kind of compelling resemblance between the two men. Another thing to consider is that the twins kept public contact at a minimum. They did not seem to "hang out" together. This is explained by Borden's reveal of the so-called "frail" old Chinese magician whose act was basically performed off-stage; ie: the man was fit enough to work heavy bowls of water but presented himself as a feeble old man who required canes and / or assistance to go to and from the theater. That was the real act. Borden would not likely risk exposure by sitting next to himself. <sep> Q: Is Borden's secret revealed as soon as the 11th minute of the movie? A: This has been unanswered for too long, so I'm just going to say it. NO. That is not him <sep> FOLLOWUP_Q: So, Borden doesn't have a twin brother?
[EX A]:
Yes
