Liang: Watching movies in which violence is portrayed as an appropriate way to resolve problems increases levels of aggression in viewers. Ttherefore, children' s access to these movies should be restricted. Sarah: Watching a drama whose characters are violent allows the audience to vicariously experience the emotions associated with aggression and thus be purged of them. Hence, the access by mature audiences to such forms of entertainment should not be restricted. The dialogue provides the most support for inferring that Liang and Sarah agree with each other that ['if violence in certain movies causes violence in viewers, access to those movies should be restricted', 'people who experience an emotion vicariously are likely to purge themselves of that emotion', 'the members of a mature audience are unlikely to believe that violence is sometimes an appropriate way to resolve problems', 'the effects of dramatic depictions of violence on audiences are at least partially understood']
