82. "Two prime examples this decade" is the clue, Sue, and my stab at the answer is "1973 and 1979". These two are prime number years within the decade (1970 to 1979) that the Quiz is all about. A prime number is a number that is only divisible by 1 or itself - if you knew that, I am sorry to be so pedantic.
