Last week, the local Primary school was visited by the Government School Inspector who was there to check that teachers were performing well in their respective classes.
He was very impressed with one particular teacher. The Inspector noticed that each time the class teacher asked a question, every child in the class put up their hands enthusiastically to answer it.
More surprisingly, whilst the teacher chose a different child to answer the questions each time, the answers were always correct.
Why would this be?
Need a hint? or the answer?
Hint: 1. The class teacher asked many questions.
2. All the children were normal kids and all of them raised their hands.
3. The children were not prompted beforehand with the questions or answers.
4. Not all the children knew the answers, but they still put up their hands.
Answer: The children were instructed to ALL raise their hands whenever a question was asked. It did not matter whether they knew the answer or not.
If they did not know the answer, however, they would raise their LEFT hand.
If they knew the answer, they would raise their RIGHT hand.
The class teacher would choose a different child each time, but always the ones who had their RIGHT hand raised.
