If an area's population was 1000 earlier and later became 1200, what happened?

Answer and explanation

Correct answer: The population increased

Direct answer: A, the population increased. Solve it by comparing the earlier and later values. The earlier population was 1,000 and the later population was 1,200. Because 1,200 is greater than 1,000, the final population is larger. The numerical increase is 1,200 − 1,000 = 200 people. If expressed as a percentage, the increase is 200 ÷ 1,000 × 100 = 20%. The figures alone do not identify the exact cause; births, fewer deaths, immigration or a combination may have contributed. Option A is correct because the later number is higher. Option B is wrong because a decrease would require a later number below 1,000. Option C is wrong because the later population is 1,200, not zero. Option D is wrong because population change does not mean that the geographical area ended. Memory cue: later number greater than earlier number means increase.
