Complete the statistics in the previous tables with the information provided in this table and state whether the following statements are true or false.

In the 19th century, life expectancy in Europe was low due to factors such as a lack of advanced medical knowledge, poor sanitation leading to widespread diseases like cholera and tuberculosis, limited access to clean water, and inadequate nutrition. High infant mortality rates also significantly lowered the average life expectancy.

Life expectancies in poor countries remain low primarily due to limited access to quality healthcare, insufficient clean water and sanitation, widespread malnutrition, and the prevalence of infectious diseases. Other contributing factors include poverty, political instability, and lack of education.

I can also help you with "Activity 3" if you provide the full statements that need to be evaluated as true or false.
