TASK DEFINITION: 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:'.
PROBLEM: 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?

SOLUTION: No

PROBLEM: CONTEXT: It is not explained, but we can theorize. We don't know when he rented those books. He might have done so before buying his own (to ensure he indeed should buy them), or because the books weren't easy (or cheap) to purchase. Also remember that instead of renting books on a subject he is well versed in, he probably became well versed on the subject thanks to renting those books. Finally, despite those books in his apartment, IIRC we are never told what those books are about. They might have had nothing to do with the seven deadly sins (John Doe wanted to avoid having incriminating evidence on his home, perhaps?), and thus all of his knowledge came from renting the books in the library. The books in his house might have been educational on a ton of other subjects or philosophies. Also keep in mind, the Internet still wasn't a thing back then. And books such as the ones mentioned (on bondage, homicide, or by Italian Dominican friars) might have not been easily found in your regular old book store. Finally, you can also claim that he rented them to make the plot move along, as this was their main lead. <sep> Q: Why did John Doe need to check out books at a public library?

SOLUTION: Yes

PROBLEM: CONTEXT: Largely he gains his confidence from Tony Stark. Their working together and sharing their personal issues caused Banner to rethink the way he thought of "the other guy". Stark coped with his condition by turning it into the Iron Man, and helping others. Banner still feared what "the other guy" would do when unleashed. This was then reinforced after he is induced into becoming the Hulk on the Helicarrier. Upon awaking in the abandoned warehouse and learning the Hulk aimed for it to prevent casualties, Banner came to realize that the Hulk isn't always a danger to others. Thusly he chose to join the other heroes in New York City to defend Earth, whereas earlier in the film he had made it abundantly clear that his only role was to identify the location of the Tesseract. <sep> Q: Why does Banner finally allow the Hulk to come out? A: Banner came to realize that the Hulk isn't always a danger to others <sep> FOLLOWUP_Q: Where does he get the confident he needs to be sure he can point the beast towards the enemy, and not towards the Avengers?

SOLUTION:
Yes
