Open-ended questions allow for more detailed and specific responses, whereas closed-ended questions restrict the possible responses to a limited set of options. Therefore, if you want respondents to provide specific information, open-ended questions are probably better. Choice B is false; studies have found high correlations between ratings made using different numbers of response options. Choice C is false; having too many response categories can lead to confusion and reduced reliability. Choice D is false; ranking can be more efficient than paired comparison when there is a large number of stimuli to rate.
