Explanation
Population census in Pakistan is conducted every 19 years, which is a definitive fact. This is correct because the fifth population census was held in 1998, and adding 19 years to that date brings us to 2017, when the sixth population census started. The QuizMaster of AnsweringExams.Com suggests remembering this by associating the 19-year gap with the nearly two-decade long wait for the next census, much like waiting for a rare celestial event, such as a solar eclipse, to occur again. Other options are incorrect because they do not align with the historical data and the actual time gap between the fifth and sixth population censuses. The topic of population census is tested in competitive exams like PPSC, FPSC, CSS, NTS, MDCAT and ECAT. Practice more at AnsweringExams.Com.
