The questionnaire is fundamental. To show your willingness to engage in communication and express yourself. It helps provide an avenue to know you better. For some girls the single word answers like 'no', 'many', 'some', 'at seaside', and 'none' leave the impression of a taciturn nature, difficult to engage with in without effort. The serious man will study it. When it is absent or reflects a taciturn character, the more conventional girl will forfeit the chance to broaden the scope of interest. It can also help reduce the noise.
