This is an unusual month - Santa, snow, and so on. This is an unusual paragraph, too. How quickly can you find out what is so uncommon about it? It looks so ordinary that you may think nothing is odd about it until you match it with most paragraphs this long. If you put your mind to it and study it you will find out, but nobody may assist you; do it without any coaching. Go to work and try your skill at figuring it out - it's usually about half an hour. Good luck - and don't blow your cool.
