I've done numerous questionnaires in my life, never a telephone poll though. Employment questionnaires, personality tests, online polls, etc. Quite often you would find that the way the question is phrased, and even more importantly, the multiple-choice answers are phrased, not only leaves a lot to be desired, but makes you want to tear your hair out. Either the question is nudging you in a certain direction, or none of the offered answers is anywhere near what you really think on the subject.
