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: 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  Q: So, everyone knows that the Tesseract is powerful, yet, they don't know what it can do? A: They have been studying its properties ever since  <sep> FOLLOWUP_Q: I first learned of the Tesseract when reading 'A wrinkle in time', do you think that was used as the inspiration for his Tesseract?
[EX A]: No

[EX Q]: CONTEXT: Agent K (Tommy Lee Jones) witnessed the death of Agent J's (Will Smith) father, who was killed by an alien in an act that could have been prevented by Agent K. Considering the time travel elements of the third movie, and the fact that Agent K from the past was aware of his future after Agent J told him, he has essentially lived with the fact that the father of one of his only friends in the universe died because of his own failures. Since the "past" elements of the movie took place in 1969, this means he's lived with this memory for some 40 years.  <sep>  Q: What happened to Agent K to make him so grumpy and emotionless? A: Agent K (Tommy Lee Jones) witnessed the death of Agent J's (Will Smith) father  <sep> FOLLOWUP_Q: So how did Agent J's father die?
[EX A]: Yes

[EX Q]: CONTEXT: While we will never know as neither boat used their detonator, I would suggest that they had each others, going purely on what was shown and what the film makers were trying to say. The Joker's previous 'gag' - which also failed - was to try and get Gothamites to kill each other for own protection or self interest as he believed it would demonstrate a general moral bankruptcy. 'You failed to kill the lawyer...' - I cannot remember how the rest of the line goes but the boat finale appears to come from a desire to repeat the exercise and Batman puts the emphasis on all of this in his final rebuke. The film also goes a long way to show that both sets of passengers specifically reject the opportunity to kill each other - even for self defence. If a comic source for this plot line does actually show this as a double - bluff then it is still irrelevant to what was actually said and shown in 'The Dark Knight'.  <sep>  Q: What did the Joker's detonators actually target? A: we will never know as neither boat used their detonator  <sep> FOLLOWUP_Q: Were the detonators for their own boat of the other boat?
[EX A]:
Yes
