Wow !! A great combination of Quant and Verbal
So solve and evaluate each option. On doing so,
A. The generalization is valid only for those birth years that do not end in two zeroes.
- incorrect. eg. 1993 + 9 = 2002.
B. The example does not exhibit the same principle as is expressed in the generalization based on it. - incorrect.
C. The generalization is valid only for those birth years in which the last digit is one greater than the second-to-last digit. - plug in numbers and you find this to be right. Keep it.
D. The example cannot be shown to be correct unless the truth of the generalization is already presupposed. - incorrect.
E. The generalization is valid only for those birth years in which the last digit is greater than five. eg. 1934 + 9 = 1943. Hence, this option is proved wrong.
Thus, C is the only right choice.
