(This question assumes that daily life has returned to the way it usedtobe before the Covid-19 pandemic.) Suppose that technological advancements in high-speed rail transport has led some people to substitute rail travel for driving to their holiday destinations. A study by Professor 0 of Nomash University found that the reduction in car travel led to fewer road trafc accidents and deaths per year, since rail travel is safer (per passenger kilometre) than our travel. a) Using the logic suggested by Professor 0, illustrate and explain with demand and supply curves new a rise in wages paid to all railtransport employees would affect the number of road accidents and deaths per year. (5 marks) (Hint clearly identify which market you will use to analyse the question.) b) How would your conclusion to part (a) change if, in addition to the rise in wages mentioned above, there is a signicant decrease in rental rates for minibuses or passenger vans? Illustrate and explain your reasoning
