Holiday makers from Melbourne to Hobart usually travel by car ferry, as they can take their own cars for visiting interesting places. However, the recent emergence of domestic airlines have caused people to prefer air travel for its very low price and shorter travel time. This has affected the travel by ferry between Melbourne and Hobart and the car hire services in Hobart. We would expect that:是项单选题，答案是
equilibrium quantity traded for travel by ferry has decreased and equilibrium price for car hire has increased.
能帮我解释下吗，我自己理解的是渡船的需求量下降了，整个需求线向左移，使得需求数量减少，满足了答案的前半句话，但是后半句就不对了呀，价格不是也跟着降的吗？
你理解错了，equilibrium price for car hire has increased 在这里得意思是HOBART这个地方的租车价格增加了，因为they can't take their own cars for visiting interesting places.而只能在这里租车，所以对租车的需求增加了！...
