Marcy developed a survey to administer to parents of college students living on campus. One of the questions on her survey was, "Describe your level of satisfaction with your child's residence life experiences." Marcy found that few people answered this question. This is likely because
◦ the item is unclear.
◦ the item is open-ended.
◦ the respondent is not in a position to answer the item.
◦ the item is sensitive.
