Answer 1

The correct answer is A. Continued to gradually rise

Step-by-step explanation:

In demographics, life expectancy refers to the average people in a zone or a country lives and that is directly linked to infant mortality, wards, epidemics, health systems, among others. Because of this, life expectancy varies according to the country and also according to time. In the case of U.S., it has been estimated nowadays life expectancy is around 79 years but this was lower in previous decades, for example during the World Wars life expectancy was around 60 years which means in general terms it has continued to gradually rise in the last decades.
