Feudalism began with people joining together in response to problems like these, danger from foreign invaders, the lack of a common currency or trade, and food shortages. So therefore they created a "system" called the Feudal System that would help them.
In most of medieval Europe, society was dependent on the feudal system, which was when a king or lord ruled large areas of land. To protect his land from attacks, the king gave parts of it to local lords, who were called vassals. In return, his vassals promised to fight to defend the king's land. If people wanted safety and defense, they had to live in a manor. People in the middle ages created small communities around a king or a lord. Most people lived in a manor, which consisted of a castle, a church, a village, a mill, and the surrounding farmland. These manors were isolated with huge walls, with rare visits from outsiders like merchants. Each manor was self-sufficient, which means that they made everything them selves, like food, clothes, and weapons. Self-sufficiency was very important in these days, because if they weren't able to grow food for them selves, there was no other way for them to get it.
The feudal system worked fine, because everyone had what they wanted and needed such as protection and food. For a peasant it was a very harsh life, if they were born there, they would probably stay there their whole life. Peasants had no rights to do anything except working for their lord, they paid very much for the right to live and grow crops on the lord's land.

Answer: Variability
Explanation:
Variability is the trait that displays variation occurring in sample of experiment and results .Variation can be present in experiment as samples may differ, condition may differ,different measuring aspect, etc.
According to the question, variability is the factor that should be considered to determine degree of difference present between data and how they are separate from each other in terms of sample structure, measurement , rate, influence etc even though it is producing same results.
The topic for the critical thinking quiz can come from any unit.
Critical thinking skills need to be imbibed in students at an early age so that their ability to face real-life situations improves. These simple quiz questions which enhance the thinking of students should be asked often. Thus the thought process can be encouraged and enhanced by asking critical thinking questions.
There are many aspects to critical thinking analysis, evaluation, decision-making, and solving the problem. By critical thinking questions, the students are asked to use their reasoning capacity rather than just memorize the text and answer books. These are the type of questions that will help the student to use his mind in the future also.
These questions can come from any unit and it is very important that the student can analyze the question and answer them. This question cannot be studied. It can only be analyzed and then provided answers to.
