[The subject is shown pictures of a bird, a rifle, a bullet and a knife and asked to select the one that does not go with the other three]

'The swallow doesn't fit here ... No ... this is a rifle. It's loaded with a bullet and kills the swallow. Then you have to cut the bird up with the dagger, since there's no other way to do it.'

...

But these are weapons, what about the swallow?

'No, it's not a weapon.'

So that means these three go together and the swallow doesn't?

'No, the bird has to be there too, otherwise. there'll be nothing to shoot.'
