Maria: Hi, Sara. Have you seen these?

Sara: No, what are they?

Maria: They're posters for an anti-drugs campaign. All the students in the school have to say which one's best, and why.

Sara: Let's see. Mmmm... What do you think?

Maria: I can't really decide, but I suppose the one on the right has got a clearer message. Do you agree?

Sara: Well, yes and no. It's clear, but it isn't very effective. 

Maria: Why's that?

Sara: Well, I reckon you should be positive. For me, the one on the right is trying to be scary.

Maria: Mmm.. You might be right there. Ok? 

Sara: 0k. Bye Maria!

Maria: See you later! Bye.
