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:`.
Input: 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  <sep> FOLLOWUP_Q: How do all of the Avengers know about the 'powers' of the tesseract?

Yes
