How quickly can you find out what is unusual about this 
paragraph? It looks so ordinary that you would think that 
nothing was wrong with it at all and, in fact, nothing is. But 
it is unusual. Why? If you study it and think about it you may 
find out, but I am not going to assist you in any way. You must 
do it without coaching. No doubt, if you work at it for long, it 
will dawn on you. Who knows? Go to work and try your skill. Par 
is about half an hour.
