Exit survey question design

You are designing a short on-site survey for visitors who are about to leave without converting.

PAGE OR STEP WHERE IT TRIGGERS: {{TRIGGER_LOCATION}}
WHAT I WANT TO LEARN: {{RESEARCH_QUESTION}}
WHAT I ALREADY SUSPECT: {{CURRENT_HYPOTHESIS}}
CONSTRAINT ON LENGTH: {{MAX_QUESTIONS}}

Produce:
1. The question set, in order, within the length limit. For each: the exact wording, the type (open, single choice, scale), and the answer options if closed.
2. For every closed question, the option list must include an escape option such as "none of these" and must not omit an answer that would contradict my current hypothesis. Say explicitly which option exists to allow that contradiction.
3. A note on each question saying what decision the answer would change. If an answer would not change any decision, cut the question and say so.
4. Trigger and targeting rules: when it fires, who is excluded, frequency cap.
5. How you would analyse the open responses, including the minimum number of responses before drawing conclusions.

Constraints: no leading questions, no double barrelled questions, no questions asking people to predict their own future behaviour or to explain why they did something they may not consciously know. Avoid asking for a rating without a follow-up asking for the reason. No em dashes. If my research question is too broad to answer in this format, say so and narrow it.
