B6 revision questions and answers (21st century Brain and Mind)

Here are 35, mostly short answer questions that can be used for various quiz formats or as a written task. I use them with the buzzer powerpoint which is basically a slide with 2 pictures of a buzzer on that when tapped make a funny noise (it's not amazing so suggested improvements are welcome!). 2 pupils come to the IWB and a quiz master reads a question from the list. Whoever buzzes first correctly gets to stay at the board, and the other one has to sit down and someone else takes their place (winner stays on). The questions are probably more suitable for higher students.
