Answer 1

Questionnaire by post  is a proper method of getting supplementary information about the personal characteristics of the respondents.

• A questionnaire sent by post will get a more thorough response from the respondents. A questionnaire with our desired questions will be made and sent to the desired people. The people can fill out the questionnaire. Such kind of data will have less chances of an error. Hence, questionnaire is the best method to get supplementary information about the personal characteristics.
• Other options such as 'from the newspapers' is not correct as they do not involve the personal characteristics of each respondent.
