The answer to your question would be that the example of an open-ended question is the following one: Why do you think Willie Mays was such a good baseball player?
Close-ended questions are those which can be answered with "yes" or "no" (1, 2 and 4). On contrary, open-ended questions are phrased with a statement that requires a response, they are not yes/no questions.
