Permenent members of the UN Security Council
and the instruction:
Try to name the five current and two former countries with 'veto power' at the United Nations.
Also, I don't think Taiwan is correct for the Republic of China, wasn't it was based in mainland China when it had the veto power? I'm not too hot on that part of history though so maybe I'm wrong.
I suggested they add the former ones as in this quiz.
