Liang: Watching movies in which violence is portrayed as an appropriate way to resolve problems increases levels of aggression in viewers.
Liang's first claim
When movies show violence as an appropriate way of resolving problems, it increases levels of aggression in viewers. Does Sarah agree that condoned violent problem-solving increases aggression in viewers?
No she disagrees. She says that watching violent characters purges the viewer of such aggression.
Liang's second claim
Children's access to movies where violence solves problems should be limited. Does Sarah agree that children should be kept from seeing movies where violence solves problems?
She doesn't talk about it. She says that access to these movies for mature audiences should not be restricted.
Evaluate
Usually on Agree questions (which are very rare), the two people fundamentally disagree, and so the correct answer isn't an explicit agreement but rather some underlying background truth or assumption they both accept.
In this case they clearly diverge on whether watching violence in movies increases aggression or purges aggression.
But it looks like they'd agree that .
Sarah doesn't comment on whether children's access to violent movies should be restricted, but given her belief that watching violence purges us of aggression, we'd have no reason to think she's worried about children seeing these movies. However, she did conclude that "we shouldn't restrict access to mature audiences", so maybe she was saying to Liang,
Goal
Ultimately, we will just pick the answer for which we feel like we have the most dual-support, an answer that could be supported if not proved by each paragraph.
