The student includes diagrams relevant to the chosen concept and topic, such as the impact of tariffs on the equilibrium price and quantity in the beef market, as well as the effects of government subsidies on the South Korean beef market. However, the diagrams are not accurately labelled, as important changes are not clearly indicated, such as the difference between Sw and Sw + tariff, or the changes in Q. Additionally, while the student discusses the changes in Qd, there is no discussion of the changes in Qs, which is essential for a comprehensive explanation of the diagrams.
