Although open-ended questions are valuable when exploring topics, it is desirable to have predefined answer options for ease of analysis. Open-ended questions are used in questionnaires during pretesting in order to:

A) uncover common themes so that they can be revised as closed-ended questions.
B) measure attitudes; they cannot be measured with closed-ended questions.
C) justify the fee charged to the client since open-ended are more challenging and time consuming to analyze.
D) measure demographics appropriately.
E) ensure there is an appropriate balance in questioning styles.
