Question 3: Sex
64. The sex (masculine or feminine) of each person must be checked on the questionnaire.
You should not determine the person's sex according to his first name because some first names can be given to people of both sexes. So, it is important that each question be asked for each person.
Example: The first name "Claude" can very well be given to a boy or a girl. It is the same case for the first name "Karol".
