Jeffery Weld asks:

*Why is it whenever* students don't do well on a national test the news agencies report one or a few particular items that were on the test by stating the test questions, then they believe it is necessary to provide the answers. *If their listeners need the answers, why should we expect students to be able to answer it correctly? *
