Teacher: 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:`.
Teacher: Now, understand the problem? If you are still confused, see the following example:
CONTEXT: I think it's deliberately ambiguous. If it's real, the inconsistencies are easily explained by Vidal's fascist belief system. These elements simply are not part of his world. If it's fantasy, then of course only Ofelia can see these thing because she imagined them. I think part of Del Toro's purpose in the film was to maintain the plausibility of both of these interpretations. <sep> Q: Is Ofelia just dreaming things to get herself in a fairy world? A: If it's fantasy, then of course only Ofelia can see these thing because she imagined them  Q: Are the things happening for real but visible only to Ofelia? A: If it's real, the inconsistencies are easily explained by Vidal's fascist belief system. These elements simply are not part of his world  <sep> FOLLOWUP_Q: When Vidal pulls the mandrake root out of Ofelia's mother's bed, is it just a normal root?
Solution: No
Reason: The answer is not mentioned in the text. Hence not answerable.

Now, solve this instance: CONTEXT: Yes, it is very realistic. While ADHD seems to be about kids who have excess energy, what it really is about is the focus and concentration. ADHD is caused because the areas of the brain that control focus and concentration are UNDER-stimulated or under-activated. So, taking a stimulant, for those with ADHD, actually activates/enervates those portions of the brain. It seems to "calm" the afflicted child or adult, but what it's really doing is allowing them to focus their efforts and energy. Now, to someone who does not have under-stimulated brain function in the area of focus and control, it just has the general, overall stimulative effect because it is a stimulant, after all.  <sep>  Q: Realism of the effect of ADHD medicine in Desperate Housewives? A: it is very realistic. While ADHD seems to be about kids who have excess energy, what it really is about is the focus and concentration  Q: Does it have the effect that the show shows on LInette who does not have ADHD? A: to someone who does not have under-stimulated brain function in the area of focus and control, it just has the general, overall stimulative effect because it is a stimulant, after all  <sep> FOLLOWUP_Q: What is the effect on people who do have ADHD?
Student:
Yes
