Why is a major decision reviewed after implementation?

Correct answer: To see whether policy is effective and fair

Direct answer: A is correct. A policy may look suitable before implementation, but its actual results can be understood only after people and institutions experience it. Review means collecting information, comparing the results with the original goals, identifying difficulties, and checking whether benefits are reaching the intended groups. If the policy is ineffective, unfair, too costly, or difficult to apply, the government can modify it. A is correct because review tests both effectiveness and fairness. B is wrong because checking whether voting occurred belongs to an election process, not policy review. C is irrelevant because weather is not the purpose of reviewing a policy. D is wrong because reviewing one decision does not decide whether Parliament as an institution is needed. Memory cue: implementation gives experience; review gives feedback; feedback helps improvement.
