A recent study showed that more than 50 percent of people who commit violent crimes had seen at least one act of violence on television during the preceding week. Many psychologists suggest that exposure to acts of violence, even when they are obviously fictional, can increase a person's propensity to commit violent acts. If government regulators were to ban all violence on television, therefore, we could expect the incidence of violent crimes to decrease by over 50 percent. The two portions in boldface in the passage above play which of the following roles？

听力原文：M: I've just been reading this amazing article about genetic engineering. The things they can do now.
W: I know. It's frightening, isn't it？
M: No, not a bit. I mean if we can produce fruit that doesn't rot, animals that eat less and produce more, what's so scary about that？ W: OK. But you know those new microorganisms that they are producing. Well,you only need a laboratory accident and the effects would be far more disastrous than AIDS, for instance.
M: Why are you always so negative？ )Soon I'll be able have a genetic screening done and they'll be able to tell me what diseases I'm likely to have.
W: OK. But what if they tell you you're going to have a disease for which there's currently no known cure？
M: If I know it's hereditary then I might think twice before having any children.
W: They can take a piece of someone's hair now and tell you all about that person's medical life. Now that could be an incredible invasion of someone's privacy.
M: How do you mean？
W: Look. So at your job interview they ask you for a piece of hair, ring you up ten days later or whatever and tell you they don't want to employ you because you've got such and such a disease and you might die in five years.
M: Don't be absurd.
W: I'm not being absurd.
M: Do you think people would let them get away with that, huh？ What is all this？ It sounds like you've been reading 1984. Why don't you look you on the practical side of things for a change？
What are the man and the woman talking about？
