This is a test question why is it a test question?

Answer:
Test questions appear in certain environments (psychologysts use them in personality tests for instance) to make sure that the patient is paying attention and reading the questions carefully. A sample test question would be: "This is a test question. Please circle letter B". If you fail the different test questions, the test may not be valid.
