A young college student had stayed up all night studying for his zoology test the next day.As he entered theclassroom,he saw ten birdcages.Each cage was partially covered with a sheet so that only the birds’legs were showing.He sat in the front row because he wanted to d0 the best job possible.The professor announced that the test wouldbe to look at each set of bird legs and give the common name,habitat,genus,species,and identifying characteristic.The student looked at each set of bird legs.They all looked the same to him.He began to get upset.He had stayedup all night studying,and now he had to identify birds by their legs.The more he thought ahout it,the madder he got.
