The plague rendered the feudal system.
The black plague was a dangerous and notably infectious disease which influenced all of Europe. It presumably was carried to Italy on a ship, expanding North and West Europe completely, including England. This disease was induced by the bacteria from rats and fleas. This event was declared as the "Black Death" because the inflammation on the skin was blue or black. This virus was spread from fleas and it would feed off of infected mammals like rats due to the dirty contingencies of people.
This disease transformed the feudal system remarkably. It destroyed 1/3 of the European people, and half of the Chinese people as well. The deaths of all these people influenced the commercial and political structure of Europeans, trade, and commerce diminished, and its economy needed to be reconstructed. After the plague desisted, there was a shift among the control of a common person and nobles. However various peasant uprisings were also busted out after the plague as well.
Answer:
The opportunity cost is the value of the Free ticket fee, the pleasure you would derive from going to your favorite venue, and the joy in seeing your favorite artist.
Explanation:
Opportunity cost is defined as the value or benefit of the forgone alternative in the course of making a decision. In this case, you are either faced with enjoying yourself at the event where your best artist will be performing at your favorite venue and at no cost and then performing badly on your ECON test on Friday, or sit back and study on Thursday so you can pass your test and then forget the event. Hence once you choose to study, the opportunity cost is the value of the ticket fee, the pleasure you would derive from going to your favorite venue, and seeing your favorite artist. Missing an autograph from your favorite artist can also be considered part of the opportunity cost.
