Researchers conducted a questionnaire investigating the relationship between daily social media use and academic anxiety in sixth-form students. At the end of the study, the researchers used the following brief statement to debrief the participants:

"Thank you for completing our questionnaire. Your responses will be very helpful for our psychology project. Do you have any questions before you leave?"

Suggest two additional points that should be added to this debriefing statement to better ensure the ethical treatment of the participants.
