If population of an area keeps changing why is attention to both voter list and demarcation necessary?

Correct answer: List updates eligible voters and demarcation relates to representation balance

Correct answer: A. Population change affects two connected parts of elections. Updating the voter list helps include newly eligible residents and remove or correct outdated entries, subject to the applicable electoral procedures. Reviewing demarcation helps keep constituencies organised so that geographical representation remains reasonably balanced under the relevant rules. A is correct because it assigns the proper function to each: the list concerns who is eligible and registered, while demarcation concerns how areas are divided for representation. B is wrong because neither process is designed to raise tax rates. C is wrong because both support orderly voting rather than stopping it. D is wrong because neither determines a candidate’s education. Memory cue: changing population requires updating both “people” and “places.”
