Dear Bill and Melinda,
Standardized tests serve the purpose to the test giver and the test maker, not the student. In many/most situations in life where a problem has to be solved there are several options from which to choose.
That sounds like a multiple choice test, but don’t leap to that conclusion just yet. Many times there are more than one right answer, and just as important as the answer is the justification of the thinking behind the chosen answer.
Try to assess that type of thinking on a standardized test. You cannot.
