Who are these boys?/ They are .../ I don't know
1st slide: test: print out for students. Sorry, it's a screen print, you can't alter it. But you can use the pictures from the 2nd slide to make your own if you wish.
2nd slide: the same pictures to show onto the white board so that students can see the pictures better and in colour.
3rd slide: same slide with answers popping up.
