If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which dates or experiences does this question ask you to consider?
What would you leave out under the seven-day wording?
What would the thirty-day wording include that the shorter version would not?
Which time-period explanation would make your answer less ambiguous?

Author notes / illustrative keys where applicable:
1. Test the actual recall boundary without supplying an answer.
2. Identify the shorter window’s exclusions.
3. Expose the changed experience set rather than attributing a trend.
4. Find a wording repair to retest with the chosen period.
