Example Input: El primer libro del Dr. Weiss sigue siendo un gran libro para todos aquellos a quienes les inquieta el tema de la reencarnación, así no crean en ella.
Example Output: Positive

Example Input: I teach The Odyssey, and let me tell you, this movie does NOT reflect the book well, if you're watching it for testing purposes (and I know you are!) However, I DO show selected scenes (out of sequence because the movie is out of sequence) just because my students think it's fun. WHEN will a GOOD version be made??? I had such hopes for Troy, and meh....My students' favorite part is the inexplicable arm action of the guard who announces "Tele-machos of Ithaka!" Scenery WILL be chewed - even the usually OK Greta Scacci comes off rather poorly.
Example Output: Negative
