Super questionnaire / Paper

When conducting a questionnaire survey among many people, the pen will not become a small problem because researchers cannot guarantee that everyone takes a pen with them. However, the appearance of super questionnaires can solve the problem well. One such super questionnaire divide into two parts. The upper half is a questionnaire, but the bottom half is coated with paint on the bottom. When using it, the respondents just need to tear the bottom half off along the middle line, and then roll it into column shape. The section coated with paint can be used to fill in the questionnaire.
