Take the following as truth: However, case studies, like any other method GAO uses, have to meet two other criteria of  accuracy and lack of bias, in the sense that the evaluator's personal, preconceived opinions about a situation do not distort reporting and that the evaluator is scrupulously evenhanded in examining all sides of a situation.
Then the following statement: "Most case studies meet criteria relating to accuracy." is true, false, or inconclusive?
Answer: Inconclusive
