Question

the graph shows population predictions.
predicted population by continent
asia africa
what is the best conclusion you can draw from studying the graph?
by 2100, africas population will reach the level of asias population in 2010.
both africa and asia will reach their highest population level in 2060.
by 2100, asias population will only be 1,000 million more than africas.
both africa and asias populations are larger than any other country in the world.

Explanation:

1. Check Option 1: Asia's 2010 population is ~4200 million; Africa's 2100 population is ~4100 million, so this is false.
2. Check Option 2: Asia's population peaks around 2060 then declines, while Africa's population keeps rising through 2100, so this is false.
3. Check Option 3: In 2100, Asia's population is ~4600 million and Africa's is ~4100 million. The difference is $4600 - 4100 = 500$ million, not 1000 million, so this is false.
4. Check Option 4: Asia and Africa are the two most populous continents, so their total populations are larger than any single country in the world, which is true.

Answer:

D. Both Africa and Asia's populations are larger than any other country in the world.
