Why did we choose those ten questions?

The answer to the question above is actually pretty simple.
Us, Keep calm, with a few members of Powerteachers, chose those ten questions because, as well as being clear, well spelt, understandable and clean; they were the ones out of the whole lot that made most sense and the ones we saw more accurate for our level (university level); this meaning, not too easy for us so that they are pips, but also not too difficult that we get stuck and have no idea how to answer them. We worked together as one and we all intervened in the selection of the questions and as always, asked the opinion of the others; so that they all had a chance to say things about the different cards our classmates had made.
