Answer to Question 1

A personal interview is a form of direct communication in which an interviewer asks respondents questions face-to-face. It offers many unique advantages:
(1) Opportunity for feedback
(2) Opportunity to follow up by probing
(3) Can be longer than other forms of surveys
(4) Item nonresponse is low
(5) Can use props and visual aids
(6) High participation rate

Personal interviews also have some disadvantages:
(1) Respondents are not anonymous and may be reluctant to provide confidential information to another person
(2) Interviewer may influence respondents' answers
(3) Expensive

Answer to Question 2

C
The three single-brand clusters are Heineken, Budweiser Light, and Coor's Light.
