the populations of asia and africa will continue to decrease at the same rate.

more people will be living in asia than in africa sometime around 2120.

Explanation:

1. Observe the trends: Asia's population rises then declines, while Africa's population steadily increases.
2. At 2100, Asia's population is ~4800 million, Africa's is ~4200 million. Africa's upward trend and Asia's downward trend mean their populations will cross soon after 2100, likely around 2120, with Africa's population becoming larger.
3. Eliminate other options:

• Asia and Africa do not grow/decrease at the same rate.
• Asia's population will not be larger than Africa's around 2120.

Answer:

More people will be living in Africa than in Asia sometime around 2120.
