Explanation:

The data shows the U.S. median age rising from 20 (1850) to 39 (2050). A rising median age typically reflects an aging population, which is often linked to increasing life expectancy (people living longer) and/or declining birth rates. Options A (poverty), B (population size), and C (income) are not related to median age data provided.

Answer:

D. Life expectancy is increasing.
