Answer: In Medieval Europe, knights pledged loyalty to vassals, who in turn pledged theirs to powerful lords, and serfs labored in the fields.
Explanation:
A rigid hierarchy refers to one where people who are born into a certain position in life, find it quite hard to move from it or rather one where there are different social classes and people had to be classified in one class for the system to work.
The system during medieval times was much like this. Social classes existed that determined a person's worth in society such as the knights, vassals, Lords and Royals. There was also the serfs who were considered the lowest in the hierarchy.

Explanation
The image shows a pie chart showing the population percentages in Florida in 2013 by age. In this graph there are 5 main groups: Dark blue color that represents the population of 19 years or less, which corresponds to 23.5%; yellow color represents the population from 20 to 39 years old, which corresponds to 25.1%; green color represents the population from 40 to 59 years old, which corresponds to 27.5%; The red color represents the population aged 60 to 79, which corresponds to 18.8%. According to this information, it can be concluded that about 75% of the population is 59 years of age or younger.
This can be verified by adding the percentages of each population 23.5% (19 years or less) plus 25.1% (twenty to thirty-nine years) plus 27.5% (forty to fifty-nine years) add up to 76.1 %.
So the correct answer is D. 59 years and younger.
