Answer:
A discursive question must be asked.
Step-by-step explanation:
Discursive questions are those in which the interviewee must provide a discourse on what was asked, offering details that support the veracity of his answer. These questions cannot be answered with just "yes" or "no", but they need well-crafted arguments and details.
For this reason, we can say that this type of question is ideal to be asked when the researcher needs answers with more specific information or when facts must be verified.
