关于more than引发歧义的问题

victoriaria

本题为OG18-SC772，原题为：
Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were last year.
(A)  Heating-oil prices are expected to be higher this year than last because refiners are paying about $5 a barrel more for crude oil than they were
(B)  Heating-oil prices are expected to rise higher this year over last because refiners pay about $5 a barrel for crude oil more than they did
(C)  Expectations are for heating-oil prices to be higher this year than last year’s because refiners are paying about $5 a barrel for crude oil more than they did
(D)  It is the expectation that heating-oil prices will be higher for this year over last because refiners are paying about $5 a barrel more for crude oil now than what they were
(E)  It is expected that heating-oil prices will rise higher this year than last year’s because refiners pay about $5 a barrel for crude oil more than they did

关于B选项的错误，除了显而易见的higher over之外，OA还提到，the comparative terms more than should immediately follow $5 a barrel，这是为什么？引发了什么歧义吗？并没有觉得有其他意思呀？请指教~
另外，关于more than容易引发的歧义，Manhattan上提到了一个是more+adj+n，如：We have even more efficient engines than before.这句话就是有歧义的，那么除了这种more than还出现过什么其他易错的点吗？如果有例子po上来更好啦，谢谢~

(A)   refiners are paying about $5 a barrel more for crude oil than they were 每barrel多5美元
(B)    refiners pay about $5 a barrel for crude oil more than they did  每barrel5美元
看出区别了吗？
A说今年比去年价格高5美元/barrel    比如去年25/barrel ,今年成了 30/barrel
B说今年 5美元/barrel ,这个价格比去年的高 ..意味着去年 低于 5/barrel
