✔ 最佳答案

change in supply 是要有factor，如成本....,题目沒有提
change in quantity supply 是要有price 變(law of supply) or change in demand

你先在圖上draw 一個有supply and demand 的圖，next demand decrease(the demand curve shift to left)，再拉條直線往下，就可看到(Qe)的change，(change in Qe=change in Qd=change in Qs)

Sorry,這題目是與price 有關，題目指出(due to a fall in market demand)(line 4)，demand curve 往左移，題目沒有說price is fixed，因此price 會下跌，(Qe 也會下跌)，(Qe=Qd=Qs)(price and Qt will remain 均衡equilibrium)
