Final answer:

Explanation:
The question, "Have you ever heard of a cola with twice the caffeine of regular colas?" asked by the interviewer during Pepsi Max's telephone survey is an example of a dichotomous question.
This is because it requires a simple 'yes' or 'no' answer, presenting only two possible options to respondents. Dichotomous questions are designed to be straightforward and tend to facilitate quick and easy responses, as they do not allow for elaboration or discussion.
