Answer to Question 1

C
Feedback:
Interviews are usually preferable to questionnaires because the quality of the data tends to be higher. Researchers using structured self-reports must decide whether to use interviews or self-administered questionnaires. Questionnaires are less costly than interviews and offer the possibility of anonymity, but interviews yield higher response rates, are suitable for a wider variety of people, and provide richer data than questionnaires.

Answer to Question 2

B
Feedback:
Good closed-ended questions are more difficult to construct than open-ended ones but easier to analyze. Closed-ended questions are also more efficient: people can complete more closed-ended questions than open-ended ones in a given amount of time. People may be unwilling to compose lengthy written responses to open-ended questions in questionnaires. A major drawback of closed-ended questions is that researchers might omit some potentially important responses. Closed-ended questions also can be superficial. Open-ended questions allow for richer information if the respondents are verbally expressive and cooperative. Finally, some respondents object to choosing from alternatives that do not reflect their opinions precisely.
