Question ID:PT31 S2 Q9 Passage:As part of a survey, approximately 10,000 randomly selected individuals were telephoned and asked a number of questions about their income and savings.  Those conducting the survey observed that the older the person being queried, the more likely it was that he or she would refuse to answer any of the questions.  This finding clearly demonstrates that, in general, people are more willing when they are younger than when they are older to reveal personal financial information to strangers over the telephone.
