Below are six questions that might be found on questionnaires. Comment on each as to whether or not it is a good question. If the question is a good question, explain why you think so. If it is not, explain why. (Assume that no lead-in or screening questions are required. Judge each question on its own merits.)
a. Do you read National Geographic magazine regularly?
b. When did you first start chewing gum?
c. How much discretionary buying power do you have each year?
d. Do you think the president is doing a good job now?
