Which of the following, if it occurred, would constitute a disadvantage for Hotco of the plan described above?



(A) Another manufacturer’s introduction to the market of a similarly efficient burner

(B) The Clifton Asphalt plant’s need for more than onenew burner

(C) Very poor efficiency in the Clifton Asphalt plant’s old burner

(D)A decrease in the demand for asphalt

(E) A steady increase in the price of oilbeginning soon after the new burner is installed


这道题答案选择E明白，但是lawyer解释说D是支持（demand减少，用油就少啦，所以H赚得越多）这个选项始终没有看懂，希望牛牛帮我解答一下，谢谢
