Could you please provide a clear solution and step by step explanation? I would be grateful. Thanks in advance.

Problem 3. (Standard trade model) [week 4] Japan primarily exports manufactured goods, while importing raw materials such as food and oil. Use the relative demand-relative supply graph in figure (6- 5) in your textbook to analyze the impact on Japan's terms of trade of the events below. In each case, (i) draw the diagram using the demand and supply curves of manufactures relative to raw materials, (ii) indicate and show in the graph whether the curves shift to the right or to the left (giving intuition behind your answer) and (iii) indicate and show in the graph how the shifts change the equilibrium world relative price and Japan's terms of trade: c) US engineers develop a fusion reactor that replaces fossil fuel electricity plants. d) A harvest failure in Russia. e) A reduction in Japan's tariffs on imported beef and citrus fruit
