Tània - Hi Amadeu. Hve you seen these?
Amadeu - No, what are they?
Tània - They're posters for an anti- racism campaign. All the students in the school have to say wich one's best, and why.
Amadeu - Let's see. Mmm. What do you think?
Tània - I can't really decide, but I suppose that one on the left has got a clearer message. Do you agree?
Amadeu - Well, yas and no. It's clear, but it isn't very effective.
Tània - Why's that?
Amadeu - Well, I reckon you should be positiva. For me, the one on the right is trying to be scary.
Tània - Mmm. You might be right there.
