Step 1
Upon reaching 65 years of age, females are more likely to live longer than their life expectancy measured at birth.
Answer
This statement accurately reflects the data observed in the graph. As indicated, the life expectancy at age 65 has shown a significant upward trend compared to the relatively stable life expectancy at birth, suggesting that reaching age 65 correlates with a higher likelihood of surpassing the life expectancy at birth.
Step 2
Life expectancy measured at age 65 has increased at a greater rate than life expectancy measured at birth.
Answer
The graph substantiates this statement, illustrating that the increase in life expectancy at age 65 appears more pronounced than that measured at birth, particularly from the mid-20th century onwards.
Step 3
Life expectancy trends are mainly due to the reduction in mortality rates among middle-aged and elderly females.
Answer
While this statement may have some truth, the graph does not provide enough detail to conclude that this is the main factor influencing life expectancy trends. It is necessary to consider broader factors such as healthcare advancements.
Step 4
Reduction in the cardiovascular mortality rate was responsible for the differences in life expectancy measured at birth and at age 65 in 1901.
Answer
This statement is not necessarily valid based on the data presented in the graph. There are various factors affecting life expectancy, and attributing it solely to cardiovascular mortality in 1901 is an oversimplification.
