Hotco oil burners, designed to be used in asphalt plants, are so efficient that hotco will sell one to the Clifton Asphalt plant for no payment other than the cost savings between the total amount asphalt plant actually paid for oil using its former burner during the last two years and the total amount it will pay for oil using the Hotco burner uring the next two years. On installation, the plant will make an estimated payments, which will be adjusted after two years to equal the actual cost savings. Which of the following, if it occurred, would constitute a disadvantage for Hotco of the plan described above?
a) Another manufactureer's introduction to the market of a similarly efficient burner
b)The clifton Aspharlt plant's need for more than one new 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 oil beginning soon after the new burner is installed 个人从字面理解，应该是挑如何才会使这家公司收入下降的选项，是weaken题。
OG给出的解释“If the price of oil goes up, then the plant will experience smaller savings than Hotco anticipated, despite the plant's using less oil than previously because of its new ,more efficient burners." 因此选E.
我的理解：Hotco的新型炉子收入=老的燃油消耗-新燃油消耗 换句话说，新炉子烧100吨油能产生老炉子烧200吨油的相同效果的话，新炉子收益=100吨节省的燃油。那么当然是油价越高，省的越多。为什么到了OG这里成了weaken的选项，实在想不明白。
我选D.因为市场对沥青的需求小了，自然生产的少；生产少代表燃油消耗小，也就对Hotco公司的依靠燃油节省收入构成了威胁
